Takuma Karashi

Takuma Karashi is the YPDA's chief investigator in Broken Minds and Broken Egg.

It is revealed, in Broken Egg, and by talking to him in Uzumaki's office that he owns dogs. He also never removes his shoes, even indoors.

Personality
Takuma is known for his insensitive manner and rude behavior. He and Ume are like two peas in a pod, snickering and making fun of others, though Takuma leans more on the outright mean side, calling Noa a "moron", and he generally has an arrogant attitude."Oh boy! I love receiving criticism! Please, tell me what I'm doing wrong!""— Takuma Karashi"

Skills
Takuma claims to specialize in "trick mysteries". By talking to him, you can learn his method of "mental violence"."I like smashing my way through crime. Mental violence. It's like a war in my brain right now. If only you could watch...""— Takuma Karashi"What exactly this means is unclear, but he is pretty articulate and generally logical, always one step ahead of Noa.

BROKEN MINDS
Takuma features heavily in the story and is the primary antagonist to Noa. Whereas Ume is a bit more sympathetic to Noa's plight, Takuma lambasts her at every opportunity.

BROKEN EGG
Takuma leads the investigation again in Broken Egg, eventually confronting the murderer all by himself without back-up, reinforcing his disregard for safety and others.
