Yuri is more shy and reserved than the rest of the club, though that doesn't mean she has a purpose in the club, she is 15 years old,  second place with Natsuki as the third youngest club member, pretty surprising, eh?

Yuri is the brains/strategist of the group, most often coming up with inventions, and commonly leading the club out of a situation alongside Monika

Though she is soft-spoken, so people far away can't hear her, and she does have issues with people thinking she is an adult and trying to hook up with her,

Also, when she has a knife, she essentially changes into a completely different, more crazy, person, though take away the knife, and she returns to normal,

either way, she is still a very helpful friend who's willing to help her club no matter what.

Her voice should be, akin to Monika, not too high pitch, not too low pitch, though give her a more softer voice, fitting the fact that she's soft-spoken, minus when she has a knife and goes into her crazy state, where you can just go nuts
