Bunri Wild 『分離 ワイルド』

In the not so far off future the amount of rebellious teenagers and trouble making delinquents are rising. To deal with this the Japanese government decided to round up all the high school students who had multiple run ins with the police and/or had major expulsions from school, and put them all in a giant high school, the size of a town, for the rest of there high school lives. Our main character, Tadakoro Daichi, one day wakes up in what seems to be a school assembly hall with a bunch of other shady looking characters. They are all told that they have been enrolled into Bunri High, the high school designed for delinquents. Without the option of escaping, there only choice is to get Wild.
