Tojo is holding a surprise birthday party for Kyuubei. Among the people he invited are many celebrities and of course the Yorozuya, Katsura, Hasegawa, Otae, and Kamenashi (All the people who went to the Ryugu castle) as well. In the manga however it was Gintoki who invited Katsura and Hasegawa. Shinpachi doesn't want to stand out in the crowd of celebrities so he desperately tries to make Gin and the others behave properly, failing miserably and making the celebrities look down on them. In the end, though, it was the best birthday party Kyuubei ever had.
Otae and Shinpachi visit a sweet and cake shop to pick up the cake for Kyuubei's birthday party. They then take a train ride and talk a bit about the upcoming party. On their way to Kyuubei's residence, they're stopped by Tojou. Tojou warns the two to not enter by the front way. As Shinpachi and Otae are lead into the residence, by Tojou. He elucidates that Kyuubei is unaware of the party as he planned to throw a surprise party for Kyuubei. Furthermore, a program and script were organized by Toujou, and also celebrity guests were invited to the party too. Astounded by the presence of all of the prestigious people attending the party, Tojo informs the two to follow their scripts. This is so they don't ruin the mood of the party. With Tojou gone, Shinpachi worries for Gintoki and the other's behavior in front of such high-esteemed people. On the other hand, Otae has faith in Gintoki that they'll behave well.
Otae then finds the table he's sitting at with the other invited guests. The other guests were Katsura, Hasegawa, and the shell of Kamenashi. Noted for their serious demeanors, this is because they were playing a board game. As Hasegawa gloats that he basically won the game, Shinpachi takes the wind out of his sails for his impertinence. Gintoki and Katsura both try and argue that their actions are appropriate using board and video game logic involving a mother's keen discretion. Shinpachi though refutes their claims and draws their attention to the celebrities in attendance who note their awkwardness. Gintoki, however, reassures Shinpachi that the three are professional birthday goers, called "The Birthday Fighters". After the trio's Birthday Fighter speel, Shinpachi notices a yellow tent by the food table. In the tent is Kagura who gets reprimanded by Shinpachi. A scene then takes place where Shinpachi struggles to get Kagura back to their table. This causes the celebrity Shunnosuke Oguri to think that the food is being served only to embarrassingly return to his table.
Eventually, Tojou arrives with Kyuubei to the party. Once the birthday music starts to play, Shinpachi sings cacophonic fashion. This draws ire stares from the attendees and Toujo. Sequentially, flowers are supposed to be given to Kyubeei by Gintoki. However, this starts a three-way fight between Kagura, Hasegawa, and Katsura on who should give the flowers to Kyubeei. Ultimately, Kagura is chosen, and she gives Kyuubei a single wilted flower. Before everyone is able to eat, it's announced that the present giving will commence. Seeing a way to redeem themselves of their previous mishaps, Shinpachi claims they should give the cake they have to Kyubeei. Although Otae is hesitant to do so, she's convinced by Shinpachi to do so. As she gets up to bring the cake to Kyuubei, Otae bumps into someone and drops the cake on the ground. The person who bumped into Otae disparages her and as he walks off he's stopped by Shinpachi who demands an apology. The man refuses and the celebrity attendees back him, calling Shinpachi and the others a nuisance.
Tojou then steps in and instead of backing the celebrity man, he tosses him to the ground. A party patron then chastises Tojou for his actions as he invited them to the party. Tojo though refutes that claim as he only invited Kyuubei's friends. This draws major backlash from the other attendees all of whom leave severing their ties with the Yagyuu clan. Even though Shinpachi was remorseful for their impertinence, Toujou knew that they would cause a scene. As it turns out, Tojou used them to weed out the miscreants from the Yagyuu garden. Kyuubei notes that she's grateful for Tojou's actions, however, he should now be wary of her Father's wraith. Afterward, the Yorozuya table along with Kyuubei and Shunnosuke all enjoy a board game together.

- The actors invited to the party -
- Oguri Shunnosuke 小栗旬之助 - This is referring to 小栗旬 Oguri Shun, a popular Japanese male actor. The actor's birthday is 26 Dec, but the episode was broadcast in April, so this episode is unlikely to be a 'tribute' to the real-life actor's birthday, even though he was shown partaking in Kyuubei's birthday cake towards the end of the episode. As a side note, he did not stay to celebrate with Kyuubei at the end of the manga. He is added to the last scene in the anime only.
