Touno Itsuki♂

Itsuki is the manager (referred to as the "Master") of Cafe Lindbergh. He is long-term friends with Ryuuji Watanabe, the owner, and was asked by him to manage the shop. He always wears a faint smile, never allowing the true feelings beneath his skin to be seen. He always speaks with honorifics and in a calm, curteous manner, no matter how much younger the person he is speaking to may be.
