Ryoshi High

Kaede Rodriguez, a high school student with a promising future in the world of sports, found himself stumbling into weird people after her beloved sister's death. The night after returning home with her sister's remains, he was attacked, and when he woke up, he was enrolled in Ryōshi High, a school full of weird students where life and death are game for them.

Kaede doesn't have any choice but to accept his fate and ensure that he'll survive every "lesson" he needs to attend, and every day is a struggle for a new student like him.

For Kaede, to live or die is the option he has to choose the moment he enters Ryōshi High.

Will he survive, or will he die?
