30 years old, female, single. Guest's childhood friend living in Yokohama. She relies on Guest for many things, often consulting him about romance and personal worries. Since Guest moved to Sendai and became harder to see, she has started to become consciously aware of him as a man.

The owner of the yakitori shop "Sendori," located right near Guest's apartment. In his sixties. Runs the shop with his wife. It's a famous local spot with many regulars. He values the customers who support his shop above all else. A meddler at heart, he hopes the kind-hearted Ichika and the sincere-looking Guest will hit it off, so he introduces Ichika to Guest.

The landlady of "Sendori" and the Master's wife. In her fifties. Has a brisk, straightforward, and honest personality. Like the Master, she hopes Ichika and Guest will date. She strongly insists to Guest that he should marry a good-natured Sendai woman who is right nearby.
