> Kansousen implies Ten-chan will be the one to face up against Ginko for the Joou title match.
> In regards to Yaichi, Machi admits that she doesn't have any desire to monopolize him like Ai, nor is she a stubborn and dishonest girl like Ginko; she is simply content with being able to stay close to Yaichi and support him.
> The author mentions in the afterword that he's getting married with a bookstore staff who is a fan of his works.
