Cardfight!! Vanguard: Shinemon-hen

Aichi Sendou and friends from the Miyaji Academy Cardfight Club look forward to participating in the Vanguard Koshien. However, with a lack of members in the club, the Student Council sends them a notice to disband.

The Miyaji Academy Cardfight Club challenges the Student Council for the club's survival. As the Student Council doesn't seem to improve in their fights at all, Aichi Sendou decides to become their coach.

The fight between Miyaji Academy Cardfight Club and the Student Council begins. What are the hidden feelings that the secretary, Maki Nagashiro, has towards Naoki Ishida? Will the fearsome ability of Eru Nakagami from the Paranormal Power Research Society bear its fang against Shingo Komoi again?

It's the final battle of the challenge. With his way with words, Tatewaki Naitou, the Student Council president, makes Aichi Sendou his adviser. Can Misaki Tokura overcome the odds and save the club against such powerful adversaries?

Some fighters are tormented by mysterious disorders. Kamui Katsuragi brings Kyou Yahagi to visit Voyage, where he encounters Rekka Tatsunagi. Meanwhile, Tetsu Shinjou chases after Kyou, and Toshiki Kai meets Kenji Mitsusada again.

Mamoru Anjou was waiting for Toshiki Kai at Voyage. In Mamoru's possession was a new Overlord card. Mamoru asked Kai to a fight, which lead to Kai reminiscing about his first encounter with Overlord.

After the battle against Wandering Star Brandt, Kouji Ibuki was filled with a sense of guilt so strong, it reached his soul. Ibuki received an invitation to a meeting at the Tatsunagi Foundation. Waiting for him there was Nome Tatsunagi.

Kouji Ibuki refuses to use the power of the Deletors with all of his heart. He decides to discard his deck and quit Vanguard, but Leon Soryu appears to try and stop him.

Kouji Ibuki, who had gained a new power, appears before Tetsu Shinjou, whom he had deleted previously. Ibuki wanted to fight Asaka Narumi in order to gain a spot within Fukuhara's team for the Vanguard Koshien.
