|Character voice(CV)||Shinsuke Sugawara|
Kei Kuramoto is the eldest son of the Kuramoto family.
The older brother of Chinatsu Kuramoto.
He is a cousin of the same age as Makoto Kohata.
He is acquainted with Akane when he was young.
He speaks Tsugaru dialect, but he is not as accented as his father and is rather close to the standard language, so he often interprets as Makoto and Akane.
Kei is generally calm at his own pace and has a calm personality.
He is a good cook, and is often pointed out by his surroundings that he has high female power.
Akane is making fun of him by saying, "You'll be a good bride."
He likes movies and reading, but he is a fierce man who keeps textbooks and school-related items on his desk.
His weak point is the ghost.
Since he is the son of a farmer, he also has some interest in agriculture and may receive guidance from his father.
However, parents are said to be able to decide his future career.
