Student Ishikawa Renji is always quiet and still, he kind of sits and reads books on the internet and ignores the people around him to avoid getting involved in anything unwanted. His reputation is a deplorable one, everyone makes fun of him for reading and studying while they cheat on every possible test they encounter. His general motto being " I can't trust anyone or anything, all people are evil and mediocre". At the same time his mental state is unstable, often having trouble adapting to new environments. Every sound he hears makes him feel anxious at times and peaceful at others.
