Hiroki is one of the main characters in Pet. He possesses memory operation skills having an "image" of goldfish. He has long spiked orange-tinged colored hair that is lighter atop his head in comparison to the strands. His caramel colored eyes can appear yellow depending on the light. Often expressing emotion, he tends to do it in extremes. Whether it is merrily spraying water to gain someone's attention, regardless that he himself becomes drenched, to angrily speaking his mind, then tearful displays when he feeling upset, Hiroki is outwardly expressive.
Pet
There are people who can get into people's mind and control their memories. This power is used to eradicate mysteries and cases or worse, to assassinate. The potential of the said power is strong enough that it is able to destroy people's mind, however, can backfire and eat up their own heart. To counter it, chains are used to lock and protect each other's weak and dangerous heart. From one's growing fear and disdain, they're consequently called as a "Pet."
