Nakoshi Susumu, age 34, is living out of his car. Between spending his days with the homeless and his nights in his vehicle, he has little to his name–but not so little that he’ll agree to be the subject of a scientific experiment. An unnerving medical student is stalking him and offering to pay Nakoshi a significant sum to test trepanation: the ability to draw out a sixth sense by drilling into the skull. Nakoshi refuses. When Nakoshi’s beloved car is towed, though, he finally agrees to cash and the operating table. At first, the experiment seems to bear no fruit, and Nakoshi’s life is unchanged. That is, until Nakoshi realizes his vision has warped in his left eye…showing him the twisted homunculus inside every human.

Himizu

Status: Finished
Genres: Drama , Psychological

Every day in Japan, 2500 people die due to any number of causes. Do you think you'll be one of the ones to die? No, of course not. Do you think you'll win the lottery? You'd like to think so, we all would. But Sumida is different. He wants the status quo to remain in every way; live a normal life, get a normal job, have normal kids, never to be anyone fortunate or unfortunate, content in normalcy. Anyone who doesn't agree is foolish, doomed to live their life scraping up a mountain that they can never conquer, fated to die in despair wishing things had been better.

When his mother kicks his father out of the house and onto the streets, he thinks he'll be fine. When his mother leaves him to live with her boyfriend, he makes the best of it. When he realizes that he's no longer average, he strives to make his life worthwhile the only way he knows how. When the demons in the back of his mind speak to him, he tries his best to ignore them.

An adventure in another world with cute girls by your side and video game-like powers–sounds like an anime fan’s dream, right?

Really, all the fantastical adventure he keeps running into is just getting in the way of his poetic dream of finding the perfect place to die. But no matter how much he risks his hide, everything seems to keep turning out okay. Follow a miserable hero like no other in this cheerfully bleak isekai comedy!
