One fateful day, in a remote alley of Sumairu-Urbem, a homeless girl is kidnapped and sent to an Underground Prison for death matches... Nuevo Faredo's Prison. Your mission —as a retired mentor— is to train her in using her new energies and protect her so she does not die in her first fight, while searching for a way to secure her freedom. Hundreds of inmates are brought in every year, and hundreds more are left forgotten beneath the cold earth. Will you be able to protect her while strengthening your party to root out the evil that plagues the inmates' hearts? I believe in your judgment.

The story is great, the characters and writing is well done and the renders are beautiful and engaging. Only docking one point off because of the insane amounts of grind. Everything costs so much yet all the jobs pay a pittance. If that wasn't enough, raising the affection level of a character requires something like 7-10 times interaction per affection level (depending on xp gain). If that wasn't enough, you have useless fetch quests that achieve nothing except make you collect apples, then wait for it to respawn, and collect more apples, all for no sense at all. If that wasn't enough, the training is insane and takes so long, and if you don't keep it up it decreases. Not to mention the constant injuries (like just why???). The only reason and the only way I continued to play this game was because I had URM installed. I used it to skip all the grind. But even constantly finding and changing variable values was tedious, there's so much goddamn useless grind in this game.
Bittersweet in the best way. I really enjoyed this story and the characters were incredibly well written. It was both heartbreaking and satisfying in the best way. I loved how each character had depth and a personal arc that pulled me in emotionally. That said, I hope future updates will include a real combat system, where stats actually influence battles instead of just being a number to meet for triggering events. It would also be great to see a more lively world, with more background characters to make the setting feel populated and alive, even if they aren’t interactive.
Gameplay is excellent - it's what most Ren'Py Sandboxes wishes they could be. Personally, I dislike the deteriorating stats mechanic, but I keep seeing it, so I guess it's the new norm? Graphics aren't exactly groundbreaking and the models are well.. garbage really.. but the few animated scenes are done well.
