However, he is only the acting Lord until Kayneth's younger niece, Reines El-Melloi Archisorte, comes of age to take his place and must constantly deal with the Clock Tower's internal politics. One day, Waver's apprentice, Gray, adopts a stray cat, much to his frustration. However, the cat is run over by a car and Waver is unable to find a way to save it. As they bury the cat, Gray hears its cry, in which Waver takes notice that his shadow has transformed into a shadow of a cat and realizes that the cat was sacrificed to put a lethal curse on him. Waver recruits two of his students, Flat Escardos and Svin Glascheit, and manages to track down and apprehend the Mage who cursed him. Unfortunately, all Waver can discover is that some unknown party wants him killed. After a discussion with Gray about what it means to save someone, Waver receives a call and heads out with Gray to handle another matter. |||

Waver explains that after the War, he traveled to Babylon in Iraq to follow Iskandar's footsteps, but was kidnapped by a rogue Mage named Barzan. Waver is then reunited with Melvin Weins, a classmate who also ended up as one of Barzan's victims. Together, they escape their cell and discover that Barzan is attempting to dig up Iskander's tomb. Enraged, Waver disrupts the magical leyline underneath the tomb, causing numerous evil spirits to attack and kill Barzan. Upon returning to London, Waver is troubled by his lingering guilt over his involvement in Kayneth's death which caused the El-Melloi family to fall onto hard times and convinces Melvin to help him buy the El-Melloi Class. Reines is intrigued by Waver's motivations and has him agree to three conditions in return for his life: assume the El-Melloi family's massive debt, find a way to repair the El-Melloi family's damaged magic crest, and succeed Kayneth as Lord El-Melloi to represent Reines at the Clock Tower until she comes of age. Waver's only condition is that he be referred to as "Lord El-Melloi II", since he feels he is not worthy to be compared to Kayneth.

The suspicion is that Ernest's body is being used for some sort of Magecraft ritual, but nobody has been able to figure it out. Upon observing the mansion's residents, Waver deduces all four of them had motive to kill Ernest; Mary stands to inherit his fortune, Alec owed massive debts to him, Fernando may be trying to steal his research and Claire was being physically abused by him. However, Alec is suddenly killed under mysterious circumstances, leading Waver to figure out what happened. He tells the others Ernest sacrificed himself in an experimental Magecraft ritual to bind his soul to the mansion, making him effectively immortal, but the ritual failed, making his spirit incomplete. Ernest's spirit attacks them, but he is destroyed by Gray, who possesses a scythe specialized in destroying the undead. With the case closed, Waver and Gray prepare to return home when Waver voices his suspicion that Mary allowed Ernest to go through with the ritual knowing it would fail.

| Waver decides to investigate why his favorite tearoom has closed down, since it has been affecting his ability to teach his class. He discovers that a magical creature has damaged their electrical system and has been siphoning electricity. He follows the trail of the creature into the city sewers where he is attacked. Meanwhile, Gray becomes concerned when Waver does not return, and asks Flat and Svin to help search for him. They head down to the sewers where they found a wounded Waver and he warns them about the beast. Svin takes Waver back to his home to treated while Gray and Flat track the creature, reflecting on how Waver's class managed to collect all of the Clock Tower's misfits who couldn't find a place anywhere else. They manage to destroy the creature and uncover the workshop of Gurdoa Davenant, who is stealing electricity for his own experiments. Waver and Svin then return, with Waver pointing out that Gurdoa violated the Mage Association's rule to keep Magecraft secret, since his siphoning of electricity has been logged by the power company and people killed in his experiments have been reported missing by the media. He then presents a decree from the Mage Association stripping Gurdoa of his position. Shocked, Gurdoa surrenders without a fight. Later, Waver admits to his students that he was partly bluffing in that he would not have been able to face Davenant in a direct battle, but recounts how "some fool" taught him that showing confidence can yield favorable results. With the tearoom reopened, Waver has lunch with Gray, Reines, and Luviagelita Edelfelt, where Luvia tells Waver the two Mage Association positions for the upcoming 5th Holy Grail War have already been filled. |||

| Kairi Shishigou reanimates a skull, stating he wants to talk with it. At the Clock Tower, Waver accepts a job from a lecturer of Spiritual Evocation, Wills Pelham Codrington, who explains how his father created the Marburry Workshop out of wasteland, but the leylines became warped, resulting in freak lightning that has killed multiple Magus, including his father, and a dozen bystanders. With Sir Trevor dead, the resulting inheritance conflict between the branches to his house would hurt Bram Sophia-Ri, the next head of Spiritual Evocation, who Waver has agreed to do a favor for. Later at a cafe, Bram and Reines speak about Waver's obsession with the Holy Grail War and how he is willing to bow down to Bram, who is supposedly trying to arrange for Waver to participate. Waver, Wills, Gray, and Reines head to Marburry. On the way there, Wills admits the main Codrington family filed a complaint about the workshop to the policies department, who claim it will breach the rule of keeping magecraft a secret and needs to be handled by them. Policies member Hishiri Adashino arrests Wills on their arrival, stating he caused the leyline disruption and death of his father. A Codrington of the main family, Waletta, claims Trevor's traces within his remains have been erased, so he can't be resurrected to answer questions, something only a necromancer like Wills can do. Since this is circumstantial evidence and a vicious storm outside prevents anyone from leaving, Waver gets permission to investigate in the meantime. While in Trevor's study, Wills shows Waver a human-sized fairy who gives a silent warning before vanishing. He says she started appearing when the workshop was completed and every time she came to "warn him," someone died. Waver wonders if The Wild Hunt, an order of fairy knights, is involved. Reines finds a hidden corridor and takes Gray to investigate. They find an underground graveyard that force Reines's Mystic Eyes to activate. Kairi, a necromancer and friend of Wills, appears when their presence attracts spirits who mistaken them for tomb robbers. He chases the spirits away and takes them back. Waletta and Adashino privately chat, revealing they are conspiring to find Wills guilty so Marburry stays out of Bram's hands and returns to the main family. In the post-credit scene, Gray wakes Waver to tell him Waletta was killed by lightning, much to his shock. |||

| With Waletta's death, Adashino is further convinced Wills is the suspect, but Waver reminds her that his investigation is not yet complete. As Gray and Kairi gather research materials, they are attacked by a Black Dog fairy, which Gray destroys. Suspicious of why a Black Dog would target Gray in particular, Kairi confronts Waver about her true nature. Waver reveals Gray is connected to King Arthur and wields King Arthur's spear Rhongomyniad, which is disguised as a scythe to protect Gray's identity. Remembering King Arthur's connection to fairies, Waver solves the case and uses a ritual to summon Faye, the fairy woman Wills can see. Waver reveals that Trevor had been using the Marburry Workshop in conjunction with Wills' Fairy Eyes to secretly murder people and turn them into artificial Black Dogs so that he can open a portal to the fairy realm. Faye confirms Waver's theory and admits she killed Trevor to put a stop to his experiments and protect Wills. However, Waver's ritual inadvertently awakens Trevor's Black Dogs, in which they begin to attack the mansion. Gray rescinds the 2nd level restraint to activate her scythe's true form, the spear Rhongomyniad, and destroy the Black Dogs in one blow, but cannot close the fairy portal. Wills knows the only way to close the portal is to go through it himself and take his Fairy Eyes to the other side, so he crosses over with Faye. In the aftermath, Adashino reveals Wills was not born with his Fairy Eyes, and they were in fact obtained by Trevor through Rail Zeppelin, an underground group that specializes in trading Mystic Eyes on the black market. Policies' true motive was to obtain Trevor's records of Rail Zeppelin of which she provides a copy to Waver. Meanwhile, Kairi advises Gray to keep an eye on Waver, since his obsession with the Holy Grail War could lead him into trouble. |||

| Seeing that Waver is clearly troubled about the upcoming Holy Grail War, Gray meets with Reines to ask her about what happened to Waver in the previous War. Reines agrees to tell Gray, but only if she goes out shopping with her. They head out to London's largest department store, Carnac, where they meet Luvia, who has become Carnac's new owner. The three girls spend the day shopping at the store until they stop to take a break. Reines then tells Gray about the nature of the Holy Grail War, as well as the fact that Waver's Servant was Iskandar. However, she does not know the full details of what Waver did during the War. Suddenly, the three girls find themselves trapped inside a bounded field, keeping them confined in an alternate version of the store. Both Reines and Luvia believe that somebody is targeting them, but Gray points out that Luvia's enchantments on the building meant to encourage customers to purchase items may have malfunctioned. Luvia leads them to the basement where the core of her enchantment, a gem encrusted Egyptian statue, is stored. Luvia single-handedly fights her way through the building's automated security system and destroys the statue, freeing them from the spell. Gray returns to Waver, intending to give him a gift, but Waver reveals that his greatest treasure, the piece of Iskandar's cloak he used to summon Iskandar, has been stolen by Rail Zeppelin. He shows a letter from Rail Zeppelin inviting him to their train that acts as their headquarters and asks Gray to accompany him. |||

| Waver, Gray, and Caules Forvedge head to the meeting point for Rail Zeppelin, where they encounter Adashino and Olga-Marie Arsimilat Animusphere, the daughter of the Lord of Astromancy. Olga-Marie warns Waver not to interfere with Astromancy's plans for the Mystic Eyes auction. Waver also notes the presence of many notable figures in the magic world, such as Karabo Frampton from the Holy Church. One of Waver's students, Yvette L. Lehrman, is also present due to her family connections. Meanwhile, Reines assigns both Kairi and Luvia to investigate who stole Iskandar's mantle from Waver. Gray meets with Yvette, who notes that she has trouble reading Gray's emotions with her Mystic Eye. Olga-Marie meets with Waver, telling him that she believes the highest class of Mystic Eyes, Rainbow Mystic Eyes, will be sold the auction and asks for his assistance in obtaining them, to which he agrees. Adashino is seen meeting with Fernando. Gray starts to feel motion sick and is helped by Karabo, who through his Mystic Eyes finds out about her connection to King Arthur. Gray confides in him that she is unsure if she's any use to Waver, but Karabo reassures her that she is necessary to him. Waver then confides in Gray that he knows if he brings back Iskandar, it is likely he will have no memory of him. No matter the result, he is determined to try and find out. Suddenly, they discover that Olga-Marie's assistant, Trisha Fellows, has been murdered and decapitated. |||

| Both Waver and Karabo examine Trisha's body, concluding she was decapitated so that her Mystic Eyes, which can see the future, could be harvested. When suspicion falls upon Karabo, he reveals he was invited to Rail Zeppelin so he could sell his own Mystic Eyes, which can see the past and proven troublesome for him. Waver figures that the murderer has some way of concealing themselves from time, as neither Trisha nor Karabo's Mystic Eyes could see the person in the future or past. Waver then confronts Adashino about her presence on the train, and she reveals she is investigating the mysterious patron behind Gueldoa and Trevor's unsanctioned experiments. Waver and Gray then head out to meet the thief, only to be encountered by a Servant, Hephaestion. She reveals herself as Iskandar's confidante and is insulted at the thought that Waver was associated with Iskandar. She attacks the two with Iskandar's Noble Phantasm, Gordius Wheel. They are able to narrowly escape, but Waver ends up being wounded. Meanwhile, Luvia and Kairi continue their investigation, surmising that the thief is someone within the Modern Magecraft Theory Department. Melvin is upset that Waver went to Rail Zeppelin without him and reveals to Reines that he used his family finances to obtain his own invitation. Back on the train, Gray and Caules do their best to heal Waver and Olga-Marie provides a special panacea to help them. Caules tells Gray about his older sister, who inexplicably renounced her position as a Mage and handed it over to Caules. Gray is confident that Caules will surpass his sister, since Waver was able to see his potential. She then prays for Waver's survival. |||

| The next morning, Waver is healed but still unconscious. Gray tells Olga-Marie about Hephaestion and Olga-Marie surmises that whoever stole Iskandar's Mantle used it as a catalyst to summon her, and that her master may be on the train. Suddenly, the train is forcibly diverted and stranded in the Child of Einnashe, a snowy forest that was once the reality marble of a Dead Apostle, making it hostile to humans. Olga-Marie decides to barricade herself in her own room, still not fully trusting Gray and Caules. Meanwhile, Kairi meets with his old friend Jean-Mario Supinerra, who has knowledge about the Clock Tower's inner workings. Kairi and Luvia ask him about a seven serial murders in London involving the beheading of people bearing Mystic Eyes, and he tells them both the Clock Tower and Holy Church investigated the case but covered up the findings. He also mentions Trisha had previously asked him about the murders as well. Back on Rail Zeppelin, Melvin arrives by helicopter and is shocked to see Waver's state. Karabo and Yvette then ask them for assistance in finding a way out of the Child of Einnashe, with the other Mages deciding to barricade themselves in their rooms. Gray and Melvin agree to help. As they venture out, Gray is caught up battling Hephaestion while the rest of the group restore the leyline and returns to the train. Meanwhile, Olga-Marie discovers a pocket space hidden in her room where Trisha's head has been. Adashino then breaks into Olga-Marie's room, thanking her for finding Trisha's head. Outside, Gray and Hephaestion continue to battle, despite risking being left behind by the train. |||

| While unconscious, Waver encounters Kayneth in a dream, who asks him what his true desire is. Meanwhile, Hephaestion temporarily suspends her battle with Gray so they can take shelter from a snowstorm, telling her that a warrior should only die on a battlefield. Hephaestion then reflects that she and Gray are similar, as they both have deep loyalty to their masters. She warns Gray that Waver will die should he enter the Fifth Holy Grail War, but Gray is determined to carry out Waver's wishes. When the snowstorm subsides, Hephaestion part ways with Gray. Luvia and Kairi visit Mary, who was a friend of Trisha. Mary tells them that Lord Animusphere abandoned Olga-Marie, and his decision was connected with the Holy Grail War and the serial murderers, which was why Trisha decided to investigate. The only clue Mary can provide is that "a man without a heart" assisted in Lord Animusphere's investigations. From the clue, Luvia realizes Adashino is somehow involved. Back at Rail Zeppelin, Gray is able to catch up with train. Adashino then gathers all of the guests and accuses Karabo of killing Trisha, explaining that Trisha took measures to preserve her head so Olga-Marie could recover it and her last words uttered Karabo's name before expiring. A recovered Waver then intervenes and contests Adashino's theory, but Rail Zeppelin supports her by stating that Karabo's Mystic Eyes would have the power to murder Trisha and removes Karabo's eyes for the auction per their agreement. After talking with Karabo and Gray, Waver is certain that Trisha's murderer and the thief are the same person and becomes determined to solve the case. |||

| Waver meets with Olga-Marie and convinces her to help him after he tells her Trisha's killer is still on the loose. Meanwhile, Kairi recruits the help of Flat and Svin as Waver secures Luvia's assistance after promising to provide personal lectures to her. He then studies a leyline map provided by Olga-Marie and, upon finding a connecting leyline between Britain and Japan, discovers Hephaestion is a fake. He also inspects a charm Trisha had been carrying when she died and realizes with the existence of the charm, Adashino's theory is impossible. The auction for Karabo's Mystic Eyes begins; Waver, Adashino, Melvin and Yvette aggressively bid for them. Waver keeps bidding despite not having enough funds in an effort to lure out the perpetrator. Once the bid reaches $500 million, Waver halts the auction to contest Adashino's theory of Trisha's death. First, he points out a critical assumption everyone on the train had made about the serial murders: they assumed the victims died since they were beheaded. In fact, a skilled Mage can easily keep a head alive. This lets them freely use the Mystic Eyes without having to rely on Rail Zeppelin to remove it. He then presents Trisha's charm, which would have protected her from Karabo's Mystic Eyes under normal circumstances, proving that a third party had manipulated Karabo into killing Trisha and performing the serial murders. As he points out that there is only one possible person with the skill and motive to carry out a plot this complex, a binding spell surrounds Caules and Trisha's head. |||

| Waver and Adashino bind Caules, who is revealed to be an imposter when the real Caules and Reines arrive thanks to a special "Touko Travel" spell cast by Flat, Svin, Luvia and Kairi. Waver then reveals that he and Adashino had been working together all along to lure him out. Caught in the act, the impostor reveals himself as Dr. Heartless, the previous head of Modern Magecraft. Waver deduces Heartless and Lord Animusphere had been working together to control information about the Holy Grail War by using the Mystic Eyes they gained from the serial murders. He further reveals that Heartless was working to create his own version of the Holy Grail: by sponsoring the Marburry workshop, including Waver in his plans due to his status as a former Master and by summoning the Child of Einnashe while linking the current leylines to Japan. Admitting his guilt, Heartless summons Hephaestion to protect him. Waver then reveals Hephastion is a "Faker" class servant, the nameless twin sister of the real Hephaestion and a body double for Iskandar meant to absorb any curses aimed at him. They retreat to the roof of the train and Heartless returns Iskandar's relic to Waver as they try to leave. Despite having it back, Waver taunts Faker with the fact that she didn't appear in Iskandar's Ionian Hetaroi, revealing her harbored hatred against Iskandar and infuriating her into attacking. Karabo, having regained his eyes, joins Gray in battling Faker. Heartless summons the Child of Einnashe to protect him, but the other Mages and Rail Zeppelin work together to defeat it. With Waver's help, Gray is able to score a critical hit on Faker, forcing her to use her Hecatic Wheel as a last resort. Gray, resolving to become someone who can protect Waver and others, removes the 3rd level restraint and uses the Rhongomyniad, firing it at Faker. |||

| In the aftermath of the battle, Heartless and Faker are able to escape and Karabo is believed to have died from the injuries he suffered. Waver and Gray recover from the battle and meet with Adashino. Waver acknowledges they still don't know Heartless' full motive for creating a new Grail and Adashino admits she is pursuing Heartless as well, since he is her older half-brother. Reines meets with Olga-Marie and they agree to form a friendship/alliance. The holiday season begins in London. While buying groceries, Gray runs into Melvin who tells her that he is holding Waver's Magic Crest as collateral against the El-Melloi family's debt and warns her that Waver will likely die if he joins the Fifth Grail War. Later, a ceremony is held at the Clock Tower to celebrate Svin achieving the rank of Pride, the third-highest rank in the Clock Tower. Svin and the other students reflect on how much they learned from Waver's instruction. Waver privately laments to Gray about his inadequacy in comparison to Kayneth, but reveals he has decided not to participate in the Fifth Grail War. He realized that his desire to reunite with Iskandar is a selfish wish to fulfill his own desires and should instead focus on stopping Doctor Heartless. He assures Gray that he will need her strength for their eventual confrontation. Gray finally gives him the present she bought from Carnac, which Waver gratefully accepts. That night, Waver encounters Iskandar in a dream. When Iskandar asks if Waver will take his place at his side, Waver politely refuses; instead intending to forge his own path in the world of the living first. Iskandar then asks Waver if he's having fun with his current life and Waver confirms that he is. The next day, Waver continues to teach his class as normal. |||

| Waver receives an invitation from Olga-Marie, so he brings Gray to meet her, unexpectedly reuniting with two of his classmates, Amleth and Camus. Both of them are experts on projection magic, and are working on technology that will allow them to create a perfect copy of the world. Camus asks to take a picture with Waver, to which he agrees. The next day, Waver wakes up to find his body has reverted to his high school age. Despite appealing for help from his friends, students, and Clock Tower faculty, nobody is able to figure the cause of his condition or how to reverse it. All he knows is that he has been afflicted by a very powerful spell affecting his and everybody's perception of him, with the risk his younger existence will completely overwrite his old one. After receiving some information from Adashino and meeting Camus again, Waver begins to suspect Camus' involvement. On Christmas, Waver attends his class reunion despite his current condition, and is surprised to discover the majority of his classmates have had little success in their careers with the exception of himself, Amleth, and Camus. Amleth then reveals his project, using Shell Projection to revert his classmates back to their younger forms. However, Waver reveals he has figured out that Amleth and Camus used him as the core of the Shell Projection, constructing everybody's younger forms from his own memories. Amleth was deep in debt, and Camus manipulated him into perfecting her research as revenge for an incident he caused that damaged her magical circuit. Camus reveals that her motive is no longer revenge before using the Shell Projection to create an entire artificial reality based on Waver's memories as a student in the Clock Tower. However, Waver predicted this and prepared protective talismans for himself and Reines to avoid being brainwashed by the Shell Projection, as well as having his students teleport Gray into the Shell Projection so she can track down its core. Gray destroys the core of the spell while Waver confronts Camus directly, telling her he realized too late how fondly she viewed him, and he assures her that he will still keep her in his memories. Moved by Waver's sincerity, Camus deactivates the Shell Projection. Afterwards, Amleth is pinned with the blame of the Shell Projection and forced to default on his debts, while Camus' status as a Mage is revoked due to the complete destruction of her magic circuit. Waver and Camus part ways amicably, and he and Gray spend Christmas together with his students and Olga-Marie watching a movie. |||
