Haruhide Shitara

He is a student at the same school as Ren and has the second highest grades right below Ren. Like Ren, he too sees the world around him rotting and respected Ren back when he was a first year student, however after watching him adapting to a student lifestyle and becoming friends with the people he views as garbage he lost all respect he had for Ren. However, he is later recruited by Ren where he reveals that he was only acting like that to use the students as his guinea pigs for his hypnotism experiments, describing its potential by stating from records of research that hypnotism can be more destructive than an Atomic Bomb. Skeptical at first, Ren then demonstrations this ability to Shitara, convincing him. Ren recruited Shitara because he saw the same urge to change the world as he himself did and also realizes for his plan to follow through he needs people he can trust to work with him. Although Shitara is highly intelligent, he appears to be easily frightened and very skeptical about some of Ren's plans; but that is easily changed with Ren's determination for his plan to succeed. After figuring out Ren's true plan with his hypnosis, to use it to releave humanity of their weaknesses, he becomes fully committed to Ren and is willing to gamble his life for Ren.
