Takamatsu is an honor student who has a polite personality and wears glasses. He mainly contributes to the SSS through intelligence gathering and other affairs but does not actively fight. Yuri herself says to not be fooled by his glasses and that he is actually an idiot. Though appearing to be slender, he works out and is actually well-built muscle-wise. After he first reveals this, he tends to take his shirt off, much to everyone's discomfort. He is absorbed by a shadow and is turned into an NPC. However, having strong enough feelings (according to Yuri), he is able to regain his senses and manages to disappear like the others.
