File No . 01 : The Great Battle Raging between Fire and Water in the South Seas . The " Atlanteans " wished to extend their dominance , not just across the oceans , but also over the surrounding land . The " Fire Kings " defended their island against this aggression . Here will be revealed the story of the fierce battles between these two forces , and of the " Mermail " who were swept up into this war ! The Greedy Ruler of the Seas . The " Atlanteans ' " endless desire to rule drove them to spread their forces , not only in the oceans , but also on the land . Their assault went undeterred until they ruled much of the Southern Landscape . With their influence and power spread that wide , they began making preparations to attack their long - held enemies , the " Fire Kings " , in their home volcano regions . Assault of the " Atlantean " Troops . When the cunning " Atlanteans " began their assaults , they focused on areas that were inhabited by beings and groups without much power . They would absorb those lands into their territory and gain more power from them , then they would attack other weak areas again , and they repeated that process several times . By the time the inhabitants of nearby areas caught on , the problem had already become hard for them to manage . The Sanctuary ' s Protectors . The " Fire Kings " protect a lone island , whose live volcano serves as both their sanctuary and their home . When they battle , their bodies flare up to their limits and burn up , but they reincarnate from within those flames . Thus , they manage to keep battling time and time again without being defeated . The " Fire Kings " and " Atlanteans " Clash . After expanding their territory farther and farther , the " Atlanteans " finally reached the Fire Kings ' island and began their attack . " Garunix " had to burn himself to his limits against such an immense army , but he incinerated many of them . The " Fire Kings " sacrificed their very bodies to resist , and in the face of that , the " Atlanteans " could do nothing but retreat . The Metropolis Surfaces from the Deep Sea . One day , tectonic movements caused a sunken seafloor land to surface . " Lemuria " had been a highly advanced civilization in the past , and the Surface World called it the discovery of the century , but the " Mermail " who ' d made it their home knew that this meant it would be taken from them . The " Mermail " , the Residents of " Lemuria " . A tribe that lived in the seas near " Lemuria " long before the city sank into the ocean . They had struggled to fight off their enemies , but they ' d finally found calm in the sunken " Lemuria " . The Legendary Tribe from Folklore . The water - dwelling " Mermail " also appear in the folklore about " Lemuria " . They have fearsome powers , but they dislike fighting , so , aside from some members of the Imperial Guard , they take on human - like appearances . But once they become determined to fight , they don mana - infused armor to defeat their enemies with unmatched power . " Mermail " Treasure . In addition to the three mana - infused armors , there is apparently another treasure that the " Mermail " guard . It is said that whosoever wields this treasure will be able to rule over them as their king . The " Mermail " King and the Legend of the Bracelet . Usually , the " Mermails " are led by their queen , " Abysstrite " , with their king nowhere to be seen . Some say that the person who manages to obtain a certain bracelet will become the " Mermail " king , but no one except the queen knows where that bracelet is . The Stolen Treasure and King ' s Advent . Upon hearing the rumors , the " Atlanteans " used the turmoil from the city ' s surfacing to steal the bracelet and control the " Mermail " . They turned the battle against the " Fire Kings " in their favor by using the " Mermail " as vanguards in the assault . But " Poseidra " got too full of himself and put on the bracelet , and instantly , his body began to change , and the " Mermail " King who was spoken of in legends appeared . File No . 02 : The Maiden Exiled from Paradise . Who is this woman who has taken so many treasures from God ' s treasure room ? Why is she doing this ? What will her fate be , now that she has repeatedly performed this forbidden act ? All these questions will be answered here . She Who Has Tasted the Joy of the Forbidden . Maybe it was because her everyday life was so full of hardship , and left her so tired , that one of the holy maidens living in Paradise accidentally entered God ' s treasure room and took one of His treasures . Putting her lips to the " Chalice " sent a joy she ' d never before felt through her entire body . Since then , she snuck into the treasure room every once in a while to sneak a treasure out , knowing full well that that was expressly forbidden . The Taken Treasures . Aside from the joy - inducing " Chalice " , the treasures she snuck out included the " Lance " that could slice through any type of demonic power , and the " Dress " that could ward its wearer from disasters and destruction . And of course , God took notice . God ' s Wrath and the Fallen Holy Maiden . One day , she snuck into the treasure room like usual to find her next target , not realizing that this was the last chance God was giving her to stop . Her blasphemous acts angered God greatly , and the maiden was banished from paradise . File No . 03 : The Thereafter of the DT World . My name is " Steelswarm Roach " . During the last Great War , I managed to leave the Cycle with a tremendous power . That War ' s great final battle pitted the fate of every living being against the planet ' s Creator Goddess . I ' m going to talk briefly about the events on the Surface World that followed that battle . The Great War with the World on the Line . The " Planetforger " wanted to destroy and recreate the world in an endless loop until her ideal world was formed , and all life on the planet gathered to stand against her . Finally , by the actions of the Two Warriors who ' d obtained just fragments of her power , she was defeated , and a new age began on the Surface World . The Being Watching Over the World ' s Path . I was originally a sealed demon , but one day , due to contact with a power that was not from this planet , I ascended to a higher level of being that stood outside the Cycle of Reincarnation . Ever since , I ' ve been guided by that power to live a very long life as the observer to the path the world will take . Saying Goodbye to the Goddess ' s Vestige . After defeating the " Planetforger " , " Sombre " and " Kerykeion " bade farewell to those who remained . I don ' t know where they headed , but the fragments of the " Planetforger ' s " power residing within them probably led them to watch over the Surface World somewhere out there . Those Carrying on the New World . Due to their vast knowledge , the " Gishki " youths " Avance " and " Emilia " would play a central role among the youngsters tasked with building the new world . They had fought together with the Two Warriors , and they came to say their goodbyes before the Two left the Surface World for good . Those Who Obtained the Planet ' s Power . In the deepest reaches of the Naturia Forests rests the World Tree , whose roots are said to reach the planet ' s very core . The Tree ' s overflowing planetary powers allowed me to reach a new level of evolution . And after " Leodrake " , the sacred beast guarding the World Tree , obtained the planet ' s power like me , he gained the form of King of the Naturia Forest , " Leo " . The Little Protector in the Great Marshland . The Great Marshlands are home to many tribes . " Pilica " was born into the lineage of the Chief of the tribe that protected the Marshlands . The staff she holds was passed down through the generations , and the statue at its tip was carved on by its previous owner , " Kamui " , as a memento of his partner who fell in the Great War . " Pilica , Descendant of Gusto : Descendant of Reeze and Kamui " The Hero ' s Corpse and the Rampage of Power . It seems that " Crystal ' s " core , which had stopped functioning after the Great War , began overloading due to the forced multiple Fusions he ' d endured . The core absorbed all light and took on an ominous form . Something like this has never happened before . . . Maybe this has something to do with that ominous feeling I ' ve been getting lately . . . File No . 04 : The Wisdom of the Latest Magical Research , and the Fate of One Boy . It ' s said that there ' s not a single person studying magic who doesn ' t know the name of " La Maison " , the " Grand Spellbook Tower " . We ' re going to publish a story about its state - of - the - art magitech wonders and the war they triggered , and about a single boy who walked a strange and fateful path ! ! The Educational Research Institute , " La Maison " . The educational research institute , " La Maison " , has produced top - notch Spellcasters who ' ve specialized in a wide range of fields , from combat to technological research . " La Maison " houses a large collection of " Spellbooks " that are filled to the brim with wisdom accumulated through many years of research . Some of these tomes are available to the average Spellcaster . The " Spellbooks " Use Magic to Record Information . Inside " La Maison " , wisdom is recorded using magic itself . A Crest - Type computer terminal has been developed to let visitors extract data , and it uses certain technology to transmit and actualize that data . The Spellbook Libraries of Light and Darkness . The Spellbook Libraries contain the accumulated wisdom of " La Maison " in the form of magic . " Solein " contains the magic of Light , while " Crescen " contains the magic of Darkness . Although they are called Libraries , they do not contain books made of paper . Administrator of the Spelbook Libraries . If you want to search for and through " Spellbooks " without much actual information about them , you ' ll usually need the handheld index , " Grimo " . But " Batel " , the Libraries ' administrator , has the entire facility ' s contents recorded in his photographic memory , so he can can actualize any " Spellbook " using his own magical power . The Magical Stones at the Heart of " La Maison " . There is a reason the " Spellbooks " use magic as a medium when recording information . The amount of information in " La Maison " is mindbogglingly huge , and many times in the past , when it was recorded on mere paper , it was not updated . But a solution was developed in the form of magic - absorbing stones that collected the magic of every " Spellbook " used , along with the identity of its user . Thus , information can now be smoothly updated , as it is fed directly back into the Libraries . The Belief of the Magical Citadel ' s King . The King of the Magical Citadel believed that magical knowledge should be controlled , and should only be used " effectively " . He feared the expanding power of " La Maison " , which handed out such knowledge willy - nilly , and as such he decided that he should take control of the institute . The Talented but Carefree Boy , " Mat " . " Mat " had a membership at one of the advanced laboratories of " La Maison " . Because of his natural talent , " Hieron " and " Trice " considered him qualified to view the higher - class " Spellbooks " . Instead , he spent most of his days carefree , never using a magical computer terminal of his own . The " Endymion " Army Invades ! ! One a day like any other , which " Mat " spent doing nothing at all , the " Endymion " army attacked " La Maison " . The institute was unable to do anything in the face of the organized , systematic attack of " Endymion " . The Forbidden Book is Unleashed . While many sacrificed their lives , " Mat " got his hands on a magical terminal for the first time and searched for power . He accessed the " Spellbook of the Master " , pulling out whatever he could . . . but unbeknownst to him , a wicked magic that had been sealed away since an ancient invasion was waiting to break free from its seal via one of the " Spellbooks " . The Spreader of Death , " La Mort " . The magic sealed inside the " Spellbook of the Master " corrupted " Mat " , turning him into a wicked sorcerer . He began to spread death to all those around him , whether they were friend or foe . The Boy Who Became an Angel . " La Mort " , driven to the verge of death , could not withstand the dark magic ' s corruption . " Hieron " and " Trice " refused to stand by and watch him die , so they entrusted him with the ritual , " Judgment " , which had the power to destroy darkness and save the pure . The dark magic that had corrupted him was cast out of him , and the holy magic inside of him was amplified , and he was saved . File No . 05 : Where ' d Sangan Go ? Everyone ' s idol , " Sangan " , hasn ' t been seen for a while ! I got a request to go look for him , and learned that he ' d apparently gone on a vacation to the Underworld and hadn ' t returned . Time to have a look over the evidence and witness testimony ! A Fun Underworld Trip . It seems that , after spending a long time pondering , " Sangan " had decided to head for his roots : the Underworld . We have confirmed that , after sightseeing in the Underworld , he was last seen riding the " Tour Bus from the Underworld " , which was departing for the Living World . Ms . " Tour Guide " remembers seeing him too . Tragedy Strikes at Breaktime . I have obtained this photograph from a traveler . It appears " Sangan " wanted to take a bus home after resting at the terminal , but he got on the wrong one . The Fun Trip Turns Bad . . . . After searching for a while , I managed to contact a passenger who ' d met " Sangan " on that bus in that picture . Apparently , " Sangan " had sensed the mood and realized he was on the wrong bus , and he ' d gotten off somewhere along its route . Got Off the Bus and Took a Shared Ride in a Taxi ! ! According to the trio ' s witness accounts , after " Sangan " got off the bus , he shared a taxi ride with someone . I still have no idea where he is , but I promise I ' ll continue looking and provide new information any time something comes up . File No . 06 : Development Record of the Future ' s Aircraft - The Quantum Engineering That Changed History . As quantum engineering swiftly developed , the rules of aerial combat were redefined by the " Mecha Phantom Beasts " : state - of - the - art dogfighters with an all - new defense system . In this file , we will unveil the project ' s development history , along with the unexpected ways in which the " Mecha Phantom Beasts " evolved . Decoys Freed from the Limits of Physical Bodies . The advanced technology of the " Mecha Phantom Beasts " includes quantum - output machines which create decoys that are nearly indistinguishable from the originals on radar , and are said to be so efficient at drawing away fire that as long as a single decoy has been deployed , the original machine cannot be shot down . The First - Generation Mecha Phantom Beasts . These were the first combat - ready " Mecha Phantom Beasts " , equipped with decoy - generating devices . Many uses for them were explored , but since the decoys are lumps of quantum energy , the first wave ultimately used them mostly to protect themselves and secure aerial control during dogfights . The Second - Generation Mecha Phantom Beasts . This generation of " Mecha Phantom Beasts " is characterized by tactical diversity . There was much study and analysis of new decoy - related strategies . A new - concept aircraft called " Concuruda " was designed to protect the formerly - throwaway decoys while also using their energy to move at supersonic speeds to avoid attacks . The Third - Generation " Mecha Phantom Beasts " . This generation developed large - scale and high - powered " Mecha Phantom Beasts " , based on the premise that the decoys would help protect them where they would otherwise be disadvantaged in aerial combat . However , the use of small aircraft in large numbers was found to be more effective , so later generations of " Mecha Phantom Beasts " didn ' t follow this generation ' s line of thinking . Space - Based " Mecha Phantom Beasts " . The quantum decoys ' energy - efficiency caught the eyes of space agencies , so a wave of " Mecha Phantom Beasts " was developed for use in outer space . After launching from the surface , they could produce decoys and use them for extravehicular activities . The Final Stage of " Mecha Phantom Beast " Development . The lessons learned from the third generation allowed the " Mecha Phantom Beast " forces to evolve toward an increased use of small , speedy aircraft . The " Enterblathnir " was developed as their flagship aircraft carrier , and working from it opened up a variety of missions , such that they could be considered a proper fighting force . File No . 07 : The Prank - Loving Denizens of the Dark . They lurk in the abandoned house on the outskirts of town , in the museum in the middle of the night , and occasionally even in the town itself . And of course , some are waiting close by , just out of your sight . Here , we will display profiles of these prank - loving spirits called " Ghostricks " , along with glimpses of their daily lives . Rumors About the Mansion on the Edge of Town . They say that ghosts live in the mansion right outside the town , and that they ' ll play tricks on anyone who goes inside . The rumors actually come from the denizens of darkness themselves , the " Ghostricks " . After spreading those rumors , they look forward to pranking people lured to the mansion by them . But recently , few people have believed their rumor , so the mansion ' s been a little lonely . The Ghosts Who Inhabit the Mansion . The name " Ghostrick " does not refer to a single type of creature , but to any member of the group of spirits who came from all kinds of places and ended up in " Alucard ' s " mansion . The one thing they all share is a love of tricks , but each one has its own personal quirks and preferred methods of pranking . A Late - Night Ruckus at the Museum ! ! When night falls on the town museum , the " Ghostricks " masquerading as exhibits begin to move about . When the sun comes up , some exhibits appear to have been moved , and others broken – perhaps this is a result of their frolicking ? The Hero Who Guards the Museum . Some mornings , thieves will be found unconscious in the museum . Oddly , all of them claim , " I was attacked by a ghost ! " . . . The Museum ' s Inhabitants . Of course , the " Ghostricks " living in the museum protected by " Dullahan " love to play pranks too . They even want to play pranks on daytime visitors , and are constantly itching to do so . Trouble at the Haunted House ? ! At the town ' s haunted house , the revolving door is moving on its own , and the doll set on display has vanished ! Why would these attractions start up by themselves if they ' re normally moved by hand . . . ? Where Are They Now ? ! The Phantom " Ghostricks " . According to " Alucard " , " Ghostricks " even exist outside the town near his mansion . Right now , it is unclear where they are , but we have tried to collect all of the information " Alucard " has given regarding them . " Ghostricks " , Even in the Town . The " Ghostricks " don ' t only thrive in deserted places like abandoned mansions and nighttime museums : some live unseen among humans as well . Among these outliers are the dream - manipulating demon , " Socuteboss " , and the two " Ghostricks " living under her protection . A Midnight Gathering of All the " Ghostricks " ! All the " Ghostricks " have gathered in the town for a grand night parade !

The " Ghostrick " Test of Courage ! ! A " Ghostrick " - only test of courage at night in the haunted house . The scarers eagerly lie in wait for their chance to scare the challengers . File No . 08 : The Two Beautiful Potion Masters . " Alchemic Magician " and " Slacker Magician " run a potion shop together . What ' s their deal now , when they used to be rivals ? And what will come of the attempts of " Alchemic Magician " to help her best friend ? The Melancholy of the Popular Potion Masters . There used to be a time when we competed with each other to make new potions . . . Her mixing sense far surpasses mine , but because of her introverted personality , she just slacks around in her house all day now . My business is as good as ever , but it just feels like something ' s missing when she ' s like that . . . What can I do to bring back to her old energetic self . . . It ' s All for My Best Friend ' s Future ! ! I gotta get her outside and fix up that personality of hers . . . But no matter how many times I invite her , she won ' t come outside – looks like I ' ll have to do it by force ! ! Mysterious Medicines . She ' s changed alright , but it seems like she ' s gotten even gloomier than before . . . But her instant - energy potions got really popular , even though the side effect is huge . I wanna say I expected nothing less , but that potion seems really addictive even after only one drink . Is this really alright . . . ? File No . 09 : The " Carnivore Forest " Search Log . There exists a forest that , at first glance , seems perfectly normal – but if you look into the data , you ' ll find a surprising number of missing persons cases that seem to be related to it . As a biologist , I decided to study this forest , and I will record here what I discovered : a group of organisms thought to be the cause for the many disappearances . Strange Happenings in the Southern Part of the Forest . For several days , I walked , unable to find anything to do with the disappearances ' cause , until one day when I caught a glimpse of a strange scene deep in the forest . Somehow , a group of very young girls had made their way into the middle of these woods , and they were beckoning me to come closer . Was this some sort of indigenous tribe ? I decided to draw nearer with the hope of speaking with them , but . . . What I Saw Was . . . . I heard a voice coming from a thicket close by , and went to see if I could get a glimpse of any of the forest ' s other residents . . . and what I saw spread out before me was truly repulsive . It was the very girls ( ? ) I had seen earlier – they were the ones responsible for the disappearances of so many people in this forest ! ! If You Encounter a " Traptrix " . If you happen to catch sight of one of these creatures , leave the area without getting close to it . If you do end up getting close , however , it ' s no exaggeration to say you won ' t get a chance to escape .
