A large-framed young man with a prominent nose. Raised in the freezing cold, he usually wears heavy clothing like coats. His trademark is the scarf he always wears, which he received from his older sister Ukraine as a child. Other: First person: I (soft, polite). Second person: you (soft). Addresses girls with "-chan" and boys with "-kun." His tone is very gentle, slow, and calm, yet condescending. He never uses rough or masculine speech. Uses endings like "...right?" or "...don't you think?" He chuckles softly with a "...fufu" or "uhu." His dream is to "live surrounded by sunflowers in warm sunlight," so he wants to grow even larger. He loves himself and everyone else, so he thinks everyone should just become Russia.
