Takiyama apparently doesn't remember what his Ultimate Talent is. He doesn't really mind, he's certain he'll remember it sooner or later, but the specifics of his memory loss are unclear and somewhat suspicious, leading him to be a little unsure whether or not the others trust him... or if he can trust himself. All he does know is his first name and that he spent time at Hope’s Peak. He's a laid back and quiet kind of guy, he's funny and actually very friendly... but still seems a bit off.
