I'm not familiar with a lot of mangas like this so I'm not that picky and I gave it five stars (then I changed it because it could've been better like the characters' personalities and ESPECIALLY creating proper motives)
It's really cool how the game was set up and I like how the main character doesn't have any shallow motivations like senseless killing.
Jesus it got really dark with that pedo child rapist guy...
