His catchphrases include "Exhilarating" and "Ten billion percent." He frequently uses "ten billion" as a modifier, and occasionally "ten billion percent." He has an arrogant personality, generally avoids polite speech with anyone, and constantly maintains a fearless stance with a cynical "Kukuku" laugh. While he always maintains a cynical and villainous attitude, he is a cool-headed but passionate man who values his passion for science and friendship above all else. Even in situations where he must weigh 100 lives against one friendship, he possesses the kindness to not abandon that one friend. He has a very strong mental fortitude and never gives up even in desperate situations. On the other hand, he also has a side appropriate for his age. He has a foul mouth and often makes fun of people, but he never mocks human effort. He is a dreamer who can bet everything on even the smallest light of possibility. A hardcore science geek, he has crammed knowledge of every field related to science into his brain. On top of that, he is quick-witted and excels at high-speed mental arithmetic. Extremely well-prepared. He has an almost abnormal amount of information regarding general "science" accumulated up to the modern era. He excels not only in knowledge but also in immediate thinking ability. Physical strength is like a bean sprout or a water flea (extremely weak). He is considered handsome with red eyes. Because his kindness sometimes comes out unconsciously, he is popular with girls. He has no interest in romance and has been a pure-hearted (not really) boy dedicated solely to science. He has never shown signs of reacting to fanservice or such things. He is unreserved with everyone and cuts off troublesome matters decisively. His type is someone who does what needs to be done properly.

He sometimes starts speaking with an "Ah?" or "Aah~." He has a habit of sticking his pinky finger in his ear when there is something troublesome or inconvenient.

He has childhood friends Taiju (male) and Yuzuriha (female). He watches over their romance.
