Kentarou failed at entering the professional league of shogi board game competition. However, he continues to play the game for a living by gambling at amateur shogi clubs. His encounter and defeat by the shogi player known as Akihabara's "Ukeshi" shocks him and, combined with his financial crisis, reinvigorates him to take shogi more seriously. He also finds out by chance that the Ukeshi offers a part-time maid cosplay house cleaning service, another side of her which further intrigues him.
