Yamashita is a first-year member of the photography club and has two upperclassmen named Tada and Ijuin. He's an attractive young man with long hair that he keeps clipped back, and he's tall and slender. Yamashita attended the same middle school as Tada, so they have had a lower/upperclassman relationship for some time now. Yamashita has a deep respect for Tada, almost like a loyal puppy. As a result, other club members have given him the nickname "Yamashita-Ken," which combines his last name with the character for dog. Despite this, Yamashita loves animals, but unfortunately, they don't seem to reciprocate that love. Additionally, Nyanko Big doesn't like him either.
