Yuma is an athletic girl and is out-going. She pretends to be always in conflict with Takaki and that he's always trying to beat her in everything. She thinks he is her rival. Takaki never bothers to ask her why she acts this way until the last episode. She blushes and stutters, giving the audience the impression that she may have feelings for him. Her best friend is Manaka Komaki.

Fujimaru's father works for the Public Security Intelligence Agency under its secret Third Division, aka Third-I, as its Vice Director. He was framed for the murder of Director Okita, and was on the run for some time as he sought to unravel the mysteries of "Bloody Monday." He is eventually found innocent, though he suffers several injuries during the series. In the second season, Ryūnosuke has gone undercover in a cult group he had infiltrated eight years ago in order to prevent a terrorist attack which has the potential to dwarf the "Bloody Monday" threat. He dies in Season 2 while trying to slow down the terrorists. He was a double agent and was known as 'Beast' among the terrorists led by Alexei (the shooter of the magic bullet). (Source: Wikipedia)
