Tomohiro Yamazaki is the zany Ultimate Polyglot. Nonsensical would probably be the best way to describe Tomohiro, as he often says things that are completely irrational and confusing. At first, it may seem that way because he switches between languages at random, but if you actually pay attention to what he says and translate it into one language, it still doesn't make sense. While he's typically very strange, when it comes down to it, Tomohiro can be surprisingly reliable, intelligently assessing situations with a calm wit. He is a foreign exchange student from Russia.

As the Ultimate Polyglot, Tomohiro has a mastery of thirty-two languages. He doesn't like the title of Polyglot much, prefering to be called the Ultimate Linguist, as he believes that his current title downplays his abilities. There are rumors that Tomohiro is actually a foreign diplomat, serving as a translator, but there's no evidence to back up that claim.

Tomohiro has a medium to medium-high voice. He has a Russian accent, as he hails from Russia, but can sometimes slip from one accent to another when speaking in those languages. He speaks pretty quickly (not too quickly, mind you), and his voice fluctuates frequently, reflecting the zaniness in his personality. If I had to compare his voice to a canon Danganronpa character, it would be closest to a Russian, more energetic Kiibo, but I'd recommend not getting too hooked up on that.
