The Birth of the Cardfight Club?!

After Aichi tells his friends at Card Capital about how his school's student council is causing problems for the Cardfight Club, he repeatedly requests for Misaki to join as the fifth member. However, she still turns him down, having mixed feelings on the matter and being insulted by Kourin for not being serious on becoming a member. Then, to quickly shut down of the Cardfight Club, the student council creates a deadline for all potential clubs with at least five members to report to the council, or else they will not be officially recognized by the school. At the last second, Misaki declares herself as the Cardfight Club's fifth member after resolving her feelings of earnestly wanting to join the club. As an initiation test and to prove herself to Kourin, Misaki cardfights Aichi.
