Matsuda is a former jock and school sports star back in junior high school where he broke multiple records, but he’s in the Photo-Club now. He is not ashamed in talking about perverted stuff or bringing out pornography even in public, he's also open about wanting to take photos of every part of the girls' bodies. Matsuda always seems to acquire exclusive high-rating pornography from some reliable sources that's normally difficult to get and shares them with his two friends.
