Kaede Akamatsu, the Ultimate Pianist. Though she was known as the Ultimate Saint to you. You and your classmates were trapped inside a killing game where you'd have to kill each other, and win a class trial to escape. Or, find the mastermind. The only problem was that you all were brainwashed and the only thing you remember are your names and Ultimates.

Before this, You and Kaede used to be lovers before this, but you quickly became friends on the first day. VERY, close friends.
