GAKU MARUKO VERSUS COMPULSORY HETEROSEXUALITY: THE MOVIE: THE GAME by aaronwrites
Fandoms: The Hundred Line -Last Defense Academy- (Video Game)
15 Apr 2026

Summary
Gaku Maruko is an ordinary teenage boy living in the Tokyo Residential Complex who has been left directionless with the start of summer vacation. With nothing to do except figure out how to grow into a somewhat self-respecting young man, he steals away the most popular guy he knows, Takumi Sumino, for a day full of assorted antics. In the midst of wasting away their lives, Gaku realizes something important about how he sees Takumi— and wishes he could put that realization right back where he found it.
In another life, that would've been it.
Gaku Maruko is a teenage soldier stationed at Last Defense Academy who just woke up from an invader-induced daydream having heavily repressed something important about how he sees Takumi. He has no way to put that realization back where he found it no matter how much force he crams it into the back of his head with. But war does not need tenderness, nor does it consider youth as more than a valuable asset. First he needs to fight, and then, uh, he'll unpack all that.
Probably.
Shit.

Summary
Shared psychotic disorder (folie à deux) is a rare disorder characterized by sharing a specific delusion among two or more people in a close relationship. The inducer (primary), who has a psychotic disorder with delusions, influences another individual or more (induced, secondary) based on a delusional belief.
* * *
Either one of them could’ve been the one to think it out loud, but as soon as it’s out there Takumi jolts awake -
[Eito tries to push and pull the feeling all at once, torn between genuine nausea and the most anchoring thing he’s felt in a while. And what a sick joke that is.]
- breathing heavily like he just woke up from a bad dream he wishes he couldn’t recall.
If only it were just a bad dream.

Summary
Eito's cognitive disorder always fascinated me, he's not just a one sided i am evil character but rather his condition leads him to believe humanity is evil, viewing people as disgusting vile monster, to such an extent he believes himself to be self righteous.
So I've decided to explore his condition im naming the Misanthropic Cognitive Disorder. I am also adding characters with similar issues in his support group, everyone will have different reactions to the condition.
Anyway I've been really passionate about this so I hope you guys enjoy it

Summary
Eito’s challenge to Takumi goes horribly right, leaving him all alone in Takumi’s body. But try as he might to make the most of it, he finds himself feeling hollow despite his victory. When the chance comes to go back and do it again, he takes it, ready to claim a less decisive victory against Takumi.
Takumi’s confused when, on the eve of day 2, he sees and hears the presence of Eito Aotsuki in his head, but he’s not stupid. Karua made him read enough romance novels to know what this is. Eito is his soulmate, and his presence in his head is there to guide them to bliss together.
