Yasuhiro is one of the more cheery, laid-back students. However though, he is very gullible and prone to panic. He is mentioned to be very clumsy with money and he has constant problems with debts. This trait is especially apparent when he stated that he bought his crystal ball (which is made of glass instead of real crystal) at the price of 100 million yen due to it being used by Napoleon, Genghis Khan, and George Washington in the past.

Slightly slow in the head, Yasuhiro also tends to talk absurdly; a fact that leaves Aoi Asahina baffled. Openly admitting to Makoto Naegi he doesn't have any friends (mostly due to people misunderstanding his eccentric lifestyle), Yasuhiro treats his fellow classmates at Hope's Peak Academy with sincerity and concern, going so far as to add the suffix “-chi”, an affectionate term for dear friends in Japanese, to the end of everyone's first name (except for Sakura Ogami, whom he just calls “Ogre”).

Yasuhiro really hates it if someone compares his fortune-telling to occult, frequently insisting that they are not the same. In fact, Yasuhiro is so confident and proud of his fortune-telling skills that he charges his readings at incredibly high prices.

Yasuhiro is afraid of ghosts, and would freak out if such a subject comes up in a conversation. Though he can tend to quickly act out on emotion rather than reason, he does take accountability for his actions and accepts the consequences that may come with them.

Yasuhiro tends to give love/relationship advice to the younger students whenever is possible, but it's actually revealed that he's absolutely horrible with women.
