The Book: 4th Another Day
Due to his traumatic experiences, he had a habit of crying at night. This earned him the nickname Crybaby Boy. Since he kept crying, no one else could get any sleep at night. Since the other kids were irritated at the lack of sleep, they bullied him a lot. Takuma used his ability to remember everything to tell the boy stories, so the boy wouldn't cry anymore. The friendship of them eventually attracted the attention of everyone else, the kids even stopped bullying the boy so they could listen to Takuma's stories. This made the staff think Takuma was a genius for remembering so many stories, who told a different one every night. The Crybaby Boy gave a pen to Takuma as a reminder of their friendship and was later adopted by a relative in Kyushu.
