Ea Yuki/Synopsis

## Plot

### Yurina Appears

   On a typical morning, Ea comes to her childhood friend Daigo Seko's house to have breakfast with him and his sister, Nonoka Seko. Later, as Ea and Daigo walk to school, she asks him to play a smart phone game called Encircled Grimzelia that she herself has been playing. However, Daigo strongly refuses and ends up hurting Ea's feelings, causing her to run off in tears.Sometime later, Ea is possessed by the monster Mad Golem, which comes to life from Encircled Grimzelia. When Daigo comes over to her house, the possessed Ea pulls him inside and attempts to seduce him before the Mad Golem emerges from her mouth, leaving her body comatose. Daigo and Yurina battle the Mad Golem and ultimately defeat it, freeing Ea from its control. Ea remains temporarily unconscious, but otherwise unharmed from the experience and has no memory of her possession.

### Ea Joins

Ea eventually discovers Yurina's existence after barging in on her when she attempts to use the bathroom. After an awkward exchange, Daigo and Yurina explain the situation to her and Ea is immediately captivated and curious about Daigo's phone and Yurina herself. During their conversation, Ea reveals she is at a much higher level than Daigo and agrees to help raise Yurina's level however she can. After Daigo leaves for work, Ea and Yurina follow him and Ea gets the idea to add Yurina as a friend support for her own copy of Grimzelia. The experiment ends disastrously as Yurina ends up destroying a portion of the store. Later, Daigo pries Ea about her memory loss and she explains that the last thing she remembered was performing a draw in Grimzelia. She demonstrates by performing an actual draw, which results in another monster coming to life; the Poison Nepenthes. Ea is immediat

   ely grabbed by the monster as it tries to possess her, but is rescued by Yurina. As a result though, Yurina herself is grabbed and swallowed by the monster. In order to rescue Yurina, Ea gets the idea for Daigo to summon her own Yurina as a friend support. Daigo does so, but, surprisingly, rather than another Yurina appearing, Ea herself is transformed, donning S Rare gear. Ea is flustered by the turn of events, but quickly proves she is capable of battling the Poison Nepenthes. However, Ea's lack of battle experience is evident as she ends up damaging the store further and the Nepenthes manages to grab her. Ea allows the monster to swallow her and, after grabbing hold of Yurina, delivers a powerful strike with her sword, destroying the Poison Nepenthes and freeing them both. Afterwards, the three clean up the store and Ea reveals that, although she has dozens of S Rare weapons, she has never once spent money on the game, apparently accumulating them through sheer luck.

### Eternal Wind Joins

Having joined Daigo and Yurina in their quest to defeat Grimzelia monsters, Ea goes out with them one evening and summons another monster from her phone; this time a ghost monster. After Yurina fails to attack the monster, Ea points out that she is at a disadvantage due to her weapon type. Ea then tells Daigo to summon her as a friend support and she equips the Ludra's Staff. However, she immediately trips and is caught by the monster and has to be rescued by Yurina. Afterwards, Ea and the others discuss the possibility of recruiting more Grimzelia players to help them, particularly the high-ranked player Eternal Wind, whom Ea agrees to contact. At school the next day, Ea tells Daigo she still has not heard back from Eternal Wind, upon which her and Daigo's phones are apprehended by Haruka Nanao, the strict, but revered class president.

    A few days later, Ea and Daigo have still been unable to recruit a friend due to Haruka continuing to take their phones away. Later that evening, Ea goes out with Daigo and Yurina to fight more Grimzelia monsters. The trio summon the monster Absorber and fight it while, unbeknownst to them, Haruka observes them. Ea is grabbed by the Absorber, which begins to drain her HP, but Ea takes advantage of her close proximity to destroy the monster with one swing of her sword. The group are then approached by a girl in a one-piece swimsuit who turns out to be possessed by a Grimzelia monster; the Mecha Scorpio. Daigo tries to summon Ea as a friend support again, but she explains that he can only summon her once per day. As the monster attacks Yurina, Ea and Daigo try everything they can think of to power her up, but are seemingly left with no options, with Ea lamenting that Daigo does not have another friend to summon. Just then, Daigo receives a friend request from Eternal Wind and, after Ea persuades him to do so, he summons her. Eternal Wind suddenly appears and Ea, not recognizing her as Haruka, is thrilled to see her in person. After Eternal Wind quickly defeats the monster, Ea vehemently expresses her admiration for her and is completely starstruck. However, after Ea points out that she will be able to see her real face soon, Eternal Wind (actually Haruka and not wanting to reveal her true identity) takes her leave of them. The next day at school, Ea meets with Daigo to discuss the situation with Eternal Wind and Grimzelia. However, they are interrupted by Rikoha, which ultimately results in an awkward exchange with Haruka.

### Yurina's Despair and Daigo's Transformation

At Yurina's insistence, Ea agrees to have an unscheduled meetup with her and Daigo to train Yurina some more. They summon a new relatively weak monster called Muscargot, but, although Yurina tries to defeat it, the monster blocks her attack with its shells. The monster then sprays Ea with digestive acids, paralyzing and dissolving. The monster then climbs on top of Ea as it apparently attempts to devour her. Ea is saved, however, when Daigo summons Eternal Wind, who quickly defeats the monster. Ea gets back on her feet, but feels strange as her stomach feels heavy. However, she and the others dismiss it as her just needing rest as they head back home.

Early the next morning, Ea becomes possessed by the Muscargot, which turns out to be a slug, which is using its Parasite skill to leech off her HP. The possessed Ea breaks into Daigo's home and the slug detaches from her, seeking to drain Eternal Wind's HP instead. Ea falls unconscious and is tended to by Daigo. She soon awakens and, seeing that Yurina and Eternal Wind are struggling against the slug (which has multiplied into several slugs), tells Daigo to use his second smart phone. After Daigo uses the smart phone to friend summon himself (turning into a girl in the process), Ea expresses her adoration for his new form and also explains to Yurina how he was able to achieve an incredibly rare Grimzelia gear by constantly reinstalling the game. After Daigo and Yurina defeat the slugs and Yurina apologizes to Ea for putting her through so much trouble, Ea happily declares her intent to continue to fight alongside them. The group then share an awkward moment as Daigo partially changes back, becoming male again, but still in female clothing.

During a Skype meeting with Daigo and Eternal Wind, Ea suggests that they inform the creators of Grimzelia about the monsters that are coming to life. However, Eternal Wind disagrees, as the creators of Grimzelia may be the ones behind it. Ea and Daigo then overhear Eternal's cat and learn that its name is Storm, which impresses Ea. Ea also remarks that she is glad Eternal Wind really is a girl, considering what happened with Daigo.

### The Snow Girl

A short time later, Ea informs Eternal Wind that she, Daigo, and Yurina plan to go on a weekend trip and assumes that Eternal will not want to go to keep her identity secret. Later, at Daigo's house, Yurina tries on a strawberry-themed S Rare outfit, which Ea finds adorable. A flashback shows that Ea had informed Daigo about a special Grimzelia bonus that quadrupled the S Rare gear drop rates (though he still he ended up having to draw 19 times). Ea confirms that Eternal Wind declined her invitation to attend and the trio head off. They first go to a game center, where Ea wishes to win a giant stuffed Yurina doll from a claw crane machine. After an hour of trying, Ea still has not won the Yurina doll, but Yurina herself wins it on the first try. After claiming their prize, the group go to a Zakka store and then an ice cream parlor, which is running a promotion for "hot guys". Ea volunteers Daigo for the promotion and he is led into the backroom.

Soon, Ea and Yurina go into the back and see that Daigo has been frozen solid and Haruka is facing down a group of Snow-Men. Seeing Daigo's phone, Ea and Yurina decide to call Eternal Wind for backup (prompting Haruka to hide as she transforms). The three battle and defeat the Snow-Men, but Yuki-Onna appears and Freezes Yurina. Ea and Haruka try to escape, but Yuki-Onna catches and freezes Ea as well. Ea is left incapacitated for the rest of the fight and is nearly killed by two Snow-Men, but she is saved by Eternal Wind and Daigo who was thawed out. Afterwards, Ea and the others, still unaware that Haruka is Eternal Wind, meet up with her and explain that they are heroes due to the Grimzelia game. After Haruka inquires about it, they also explain that they went to the mall without Eternal Wind because they wanted to buy some surprise gifts for her.

### A Trip to the Beach

With summer upon them, Ea tells Daigo and Haruka that they should all go on a trip to the beach. However, Daigo and Haruka are exhausted from staying up late and more preoccupied with the Grimzelia monsters. Ea explains that going to the beach would actually be a good way to track down the monsters since the girls they possess always wear one piece school swimsuits. Daigo and Haruka agree to her plan and Ami and Rikoha decide to tag along as well.

At the beach, Ea and the others begin to have fun, but quickly run into trouble when Haruka faints. Ea and the others attempt to revive and Daigo accuses Ami of being a monster due to her swimsuit and her drawing a picture of the suffering Haruka. However, Ea and the others explains to Daigo that Ami has always tended to wear her school swimsuit and she simply has a fetish for suffering girls. Ea, Daigo, and Yurina then begin to look for Grimzelia and eventually discover three small girls in school swimsuits. After the girls dive into the water, Yurina tries to rescue them, but is dragged down with Daigo going after her. Once Daigo reemerges, he explains to Ea that the girls were, indeed, monsters, but he too is dragged down into the ocean. By using friend support on Daigo's sub-account phone, Ea is able to save Daigo, summoning him to her side and also transforming him into his female form. Daigo dives back under the water to rescue Yurina and Ea chases after him, but is stopped by Eternal Wind, who warns her that the monsters are very strong. The two then devise a plan to get Daigo's phones to him and equip a variety of weapons to fight the monsters. As the two dive into the ocean, they find that Daigo is locked in combat with the three monsters. However, two of the monster break away and one of them, a ghost type monster, attacks Ea. Although Ea assures Eternal Wind she can handle it, she is quickly overwhelmed. The monster, Clicone, suck's Ea's brain, greatly reducing her intellect. Having lost her senses, Ea uses her Gyoppi Staff's "Wild Goldfish" skill to cast the "Berserk" status on the Clicone, causing it to savagely attack Eternal Wind. However, Eternal Wind manages to defeat the monster and brings Ea safely back to the surface.

After Yurina and Daigo defeat the remaining monster, Daigo shows Ea that the phone she gave him was destroyed, but she forgives him. They then discuss the events of the battle, particularly Daigo's attempt to revive Yurina with a kiss.

### The Festival

    After their adventure at the beach, Ea takes everyone to her vacation home and she and other girls (minus Haruka) take a bath together. When the girls start to discus Dago's relationship with Yurina, Rikoha asks Ea how she feels, believing that she has romantic feelings Daigo. Ea denies it, claiming that sees Daigo as more of a brother. After the girls get dressed, Ea puts on a yukata, giving Rikoha the idea for all of them to wear yukata to the festival. This prompts Daigo to give Yurina surprise S Rare that will allow Yurina to wear a yukata, but the attention Daigo gives to Yurina causes Ea to feel despondent, though she is unsure why.

At the festival, a jealous Ea tries to join in on a goldfish-catching game that Daigo and Yurina are playing, but Daigo stops Ea, saying she is too clumsy. After Rikoha, Haruka, Ami, and Nonoka take their leave, Ea wins first prize at a lottery stand, but is still downhearted as she finds Daigo is still paying more attention to Yurina. Ea then tries a rifle-shooting game, but when she is unable to hit the target, Daigo appears and gets the prize on the first shot. He gives the prize to Ea and explains that, while it would be a waste for her to try the shooting game, it's fine if he does it himself since he can get it on the first shot and, thus, it is not a waste of money. He also tells Ea she can count on him, which pleases her.

Meanwhile, a dejected Yurina is unwittingly abducted by the Chief from Grizel Cafe, who turns out to be a Venomous Moon Jelly. The monster poisons her and, when Daigo sees Yurina's poison status, he and Ea rush to her aid. However, Daigo is unable to do anything as he has used up his friend summons for the day. The Venomous Moon Jelly attempts to finish off Yurina, but, using her luck of the draw, Ea blocks the attack by summoning another monster from her phone. However, this results in Ea summoning several other monsters to block the attacks of the other monster, and the group is soon surrounded. Yurina begins to argue bitterly with Ea, saying she has made the situation worse and Ea retorts in kind. Ultimately, Yurina is able to win the battle by having Daigo draw four more Villager's Swords and create the Corona Blade, though the Venomous Moon Jelly gets away. With the battle over, Ea and Yurina begin to praise each other, but quickly become bitter again as they remember their feud.

### Ea's Abduction

With the festival over, Ea returns home with Daigo, Yurina, and Nonoka, though she is still bitter towards Yurina. While Yurina expresses her gratitude to Daigo, Ea aggressively belittles and demeans her. Their hostility towards each other results in a minor altercation, after they which they take a bath together and have a heart-to-heart talk. Yurina demands to know why Ea is so upset and asks if she is in love with Daigo. Ea denies it and asks Yurina the same, though she too denies it. Once their bath is over, Ea takes her leave, stating that she will be at the meeting with Ami.

Later that night, Ea joins Daigo and Yurina as they walk to the Grizel Cafe to meet with Ami, but they are stopped by a woman in a business suit who asks for Ea. Ea identifies herself and the woman reveals herself to be Lamia, a Grimzelia monster. Ea is grabbed by Lamia and promptly swallowed whole by the monster, who then attempts to leave with her in tow. Inside Lamia's stomach, Ea quickly falls unconscious and her clothes. She is unknowingly joined by Yurina who is also swallowed in an attempt to free Ea, although this plan fails. Yurina is soon freed by Eternal Wind, but Ea remains trapped. Despite their best efforts, Daigo, Yurina, and Eternal Wind fail to defeat Lamia and Ea is taken away.

Ea is later released from Lamia's body at her hideout and is taken under custody by Rebecca. She awakens inside a cage, dressed in a swimsuit, but uses her natural luck to undo the lock. She eats some nearby rice crackers, not knowing they were meant for Lamia, causing Rebecca much distress when she returns. Despite her situation, Ea apologizes, but Rebecca wheels in a large array of smart phones, ordering her to summon Grimzelia monsters. Ea performs draws, but is only able to draw gear, much to her and Rebecca's confusion. Ea also performs a draw on Rebecca's phone and draws the SS Rare Dainsleif. Over the course of their conversation, Ea and Rebecca begin to form a friendly relationship. Ea suggests Rebecca team up with her and her friends to stop Lamia, but Rebecca refuses, saying she could never team up with a human.

### Rescuing Ea

Ea continues to bond with Rebecca, playing video games with her and exploring the parameters of her luck. Though Ea still wonders why she summoned monsters when she was with Yurina and Daigo.

As Daigo and Yurina's group invade Lamia's base, Ea is taken by Lamia and strapped to a chair where she is forced to perform gacha draws. Surprisingly, this time her draws result in her summoning monsters, much to Ea and Rebecca's confusion. Regardless, Ea defies Lamia and assures her that Daigo and the others will save her.

Later, Marimo, one of Daigo and Yurina's allies, finds and attempts to rescue Ea, but she is quickly overpowered by the monsters that are guarding Ea, and is turned to stone. However, Ea manages to discreetly grab hold of Marimo's smart phone, which she had secretly given to her earlier.

Ea continues to draw monsters for Lamia, but also discreetly uses Marimo's smart phone. She sees that Marimos has been petrified, but there is no known cure for it. Venomous Moon Jelly then arrives and poisons Ea, putting her into a deep sleep that she will not awaken from unless she is given an antidote. Fortunately, Daigo and Yurina's group soon arrive and defeat Venomou Moon Jelly. They administer the antidote and Ea is finally freed.

Now reunited with her friends, Ea thanks everyone who came to her rescue and has a heartfelt reunion with Daigo. Although, after some coaxing from Ami, she clarifies that Daigo is only her friend. Ea also finally makes peace with Yurina. Ea then joins group so they can defeat Lamia once and for all.

They battle Medusa who has already petrified Marimo, Honoka, RIn Mei, and Karasu. Yurina defeats Medusa, but they are then attacked by a woman in grim reaper garb. The grim reaper woman then injects a fluid into Medusa, turning her into a mindless monster that petrifies Saori and Haruka. The woman is then revealed to be human; the Grimzelia designer Yamada Rinko. After the Medusa monster petrifies Ami and Riho, Mayu and several other monster girls appear and reveal that Daigo is the Second Demon King. Mayu also explains that this is also the reason Ea only summoned monsters when Daigo was around, because they were attracted to him. The monsters then use Ea and Yurina to arouse Daigo and awaken his Demon King powers, after which he defeats Yamada.

### The Final Battle

Afterwards, Daigo and Medusa are both reverted to their normal forms and Ea uses a special drop item to depetrify everyone. Lamia then appears alongside the other monster girls and they make clear their intention to mate with Daigo to create a new generation of monsters. Although Ea and the others do all they can to fight off the monsters, Daigo is ultimately caught and, to everyone's surprise, devoured by Lamia.

Lamia transforms and injects eggs into the bodies of the Rankers to start up a new generation of monsters. She attempts to inject Ea, Yurina, and Haruka with eggs, but Daigo's will prevents her from doing so. The Rankers then rescue Daigo by invading Lamia's body, but they themselves remain trapped inside. Also, since Daigo's will is no longer affecting Lamia, Ea, Yurina, and Haruka are injected with her eggs. Neverthless, Ea and the others continue to fight Lamia and are able to recruit Rebecca to fight with them. Ea and Haruka are nearly swallowed by Lamia during the battle, but are saved by Rebecca. Unfortunately, Rebecca herself is devoured by Lamia who then changes into an even stronger form. Ea and the others are immediately overwhelmed by Lamia's new power. However, after using a special ticket provided by one of Lamia's former comrades, Haruka reobtains the Brionac, finally revealing her identity to Ea and the others as Eternal Wind. Ea and the others are overjoyed that Eternal Wind is still alive and Haruka quickly enacts an ingenious ploy to stop Lamia from swallowing anyone else. Yurina then equips the Ultra Rare Chaos Caliber and finally destroys Lamia.

 Afterwards, everyone Lamia absorbed is released and all the monster girls return to the world of Grimzelia. Consequently, Yurina also apparently returns to Grimzelia, her mission having been completed, and she bids a tearful farewell to Ea and the others before disappearing.
Three days later, Ea, Daigo, and Haruka discover Yurina hiding in Daigo's closet. Apparently, since Yurina considers Daigo's house to be her "home" now, she is free to live in the human world.
