|Японское имя:||豊穣 礼佑|
SpoilerAccompanied by some drawings, his "Super Vision" diary is a coloring book that gives a small summary of the activities he will perform for the day. However, not only is there a large time gap between the entries, the diary only shows three of them per day: morning, noon and night. It does have a certain advantage of giving Reisuke all three entries at the same time, which allows him ample time to carefully plot his next move.
Reisuke comes from an unhappy background where his parents neglected him and his family was gradually falling apart. He is highly intelligent for his age, yet still possesses both a child's innocence as well as a child's cruelty. Often, his actions make it difficult to tell which of the two traits is the more dominant. During his time at the Amano household, Reisuke grows fond of Yukiteru and especially Yuno; calling them brother and sister. Due to his size, Reisuke improvises with non-visual weaponry such as poison syringe and cyanide gas.
