山猫さん

The owner of the only restaurant in the Lost Forest, "Restaurant Solitude". Though he speaks gently and politely and has a seemingly calm personality, it doesn't feel genuine, but instead, feels cold and impersonal. He shows interest in Tiana, and when the opportunity arises, he tries to "eat" her, but Ookami-san interjects before Yamaneko-san can succeed. Ookami-san claims that something bothers him about Yamaneko-san's restaurant and Yamaneko-san's being in the forest, but cannot provide a reason.

According to his ending bonus "Secret Memo", Yamaneko-san's real name is Fredi, his favourite food is apple pie, favourite colour is yellow and his hobby is magical research.
