Today’s Tsu Terakado concert is another lively success. But fan club president Shinpachi is angered because only four of the Tsu Terakado fan club members have come to the concert. He is further enraged to learn that many of the club members have left without permission and have joined the new Tsusentai fan club instead. To Shinpachi’s surprise, the Tsusentai leader is Hijikata, who thanks to the demonic sword’s curse has now become a charismatic otaku! Can Shinpachi protect his only(?) distinctive trait from Tosshi’s onslaught?!

The fierce battle begins over the title of the Official Tsu Terakado fan club. Tosshi, Hijikata’s loser otaku personality created from a demonic sword, was once thought to have been defeated by Hijikata’s strong will, but in reality the personality still survives within him. By reigning as the king of otaku, Hijikata plans to put Tosshi’s soul to rest. Tosshi’s road to the king of otaku versus Shinpachi’s love for Otsu-chan. Who shall be victorious?!

The preliminary round for the Official Tsu Terakado fan club title is a marathon race. With Takachin in critical condition and Kagura taking the wrong route, team Shinpachi’s chances of winning look slim. But thanks to Gintoki’s quick thinking, Takachin makes an instant (and improved?) recovery and emerges from the hospital to rejoin the race! As the race gradually turns into a battle of deception, Shinpachi runs furiously for the goal. Will he be able to beat the tactical general Tosshi?!

Tosshi finishes the preliminary race in first place by rounding up all the contestants to block Shinpachi’s team from making the goal. Despite Toshi’s scheming, team Otsu-chan fan club makes a surprising comeback to finish in second place! Hijikata points out that the team cheated by changing their member lineup, but with his own member suspected of using a taxi, the objection is dropped. Kondo and Kagura also finish the race after taking the wrong route and being dropped off by the police. Meanwhile, what happened to Shinpachi who’s still in the race? That being said and done, the main event finally takes place!

For the second round in the Official Tsu Terakado fan club championships, it is a battle of charms. Both teams must come up with a virtualized situation where the winner is decided by Otsu-chan saying “yes.” First up is the Tsusengumi’s story, taking place in a bar with a beautiful night view. But the romantic mood is ruined thanks to Okita the narrator and assistants Kondo and “Mohawk” Yamazaki going out of control. Hijikata begins to panic, but with Kondo and the others’ carefully crafted stage direction he succeeds in asking Otsu-chan out. Shinpachi’s team find themselves in a tight situation, but...?

The time to settle the battle for the official fan club title is finally here. The match between Shinpachi and Hijikata is a card battle using Otsu chip playing cards. Never knowing such a thing existed, Shinpachi rushes to the vendor for some cards. Hijikata on the other hand is fully prepared and delivers the ultra powerful card “Melancholy 5-minutes before start”! Hijikata’s range of powerful attacks forces Shinpachi to stay on the defensive. Can he possibly find a way to make a counterattack?

After an intense battle, Shinpachi and Hijikata both fall to the ground with zero life points. Despite being exhausted and battered, the two men rise up to resume their battle. They fight as if their lives—no, their very souls—were on the line and Otsu begs them to stop. But nobody can stop them now. For their battle is no longer just for the title of official fan club...
