Kikuko Kobe

About

Hitoshi's paternal cousin who lives in Aomori; she refers to Hitoshi as onii-san ("big brother"). She is an excellent skier and helps her father to run a hot-springs resort. Growing up she was very much a tomboy and she and Hitoshi would play often such as "Doctors and Nurses," in which case she took on the Doctor role. She used to have a crush on Hitoshi since he wanted to marry her when they grew up—even having a sense of rivalry with Saati—but now sees Hitoshi and Saati as the resort's "honeymoon couple."

She is based on Ken Akamatsu's actual cousin, Kikuko.
