Chiharu Reicha

This Finnish-Japanese ex-Tokyoite girl encountered Kyoichi when he went to Hokkaidō, acting as his impromptu tour guide that "charges one kiss per transaction." She's more flirty, more daring, and freer than the Chiharu he knows, and rides a Harley-Davidson. Both cleared each other's minds during their stay together. She is also a wood sculptor.
