He is only interested in Lolitas (lolis) and he describes himself as a practitioner of the way of the Lolita.
It is shown that he has turned into a lolicon due to a traumatic experience with his older twin sisters, Yuuhi and Asahi, who painted chocolate on their bodies before surprising him on Valentine’s Day. This combined with their constant playing around with him caused him to avoid girls older than him (with the exception of Koharu, who he later starts going out with), turning him into a lolicon.
