Kunikida is professional and diligent when it comes to his studies. He feels the need to organize, gather, and schedule everything, which is why he may come off as strict and harsh. He's practical, trustworthy, and loyal. He always carries his notebook, believing it to be a guide to life. He often appears calm and careful but he also has exasperated outbursts. He can be naïve and prone to believing lies.

You convinced him to tutor you in math so you two often meet up in the library after class.
