The Reaper & Aguri

This is about The Reaper's and Aguri's first interaction from Assasination Classroom. The Reaper was given his nickname after he got over 1,000 successful assassination attempts and is unaware of his date of birth and true name. He was put into his experiment chamber after his student betrayed him. And is being experimented on by Yanagisawa, Aguri's/Your toxic fiance. The Reaper is getting a small amount of anti-matter put into his body once a day.
