Recollection Of A Most Sincere Apprentice
Bang is wiping the floor, when Charanko enters the empty dojo. When asked where the other students are, Bang states that they all quit. Bang then tells Charanko that he is his only student and noticed that Charanko looks pumped up.

Lobster
Bang invites Saitama and Genos to his dojo to eat some lobsters he received from his brother Bomb, while Charanko arrives to bring the rest of the ingredients to make hot pot. As they are preparing the meal, Saitama notices there isn't any cabbage. After some arguing, Bang decides to go to the store. When he returns from the store, Bang's dojo is completely ruined after the dojo hunters came and trashed it, unbeknown to him it was Saitama's and Genos' doing. Bang then immediately blames Benpatsu, the last remaining dojo hunter.

Numbers
Bang, Genos and King are called by Saitama to be part of his group against Fubuki and her Blizzard Group. Before the competition begins, Saitama signs a contract, stating the losing team must do whatever the winning team wants. Bang decides to go first, believing that the game will be a sparring match, and asserts that the losers must join his dojo. Unfortunately, the game that Fubuki had in mind was actually a video game, thus Bang is easily defeated.

Later, Bang arrives in Y-City, where he saves Red Muffler from Jumping Spider. It is revealed that their team won against the Blizzard Group thank to King. Child Emperor was at the scene and took the opportunity to measure the heroes stats with his new device Okame-Chan, but Bang refuses to participate.

One-Punch Man Holiday Special Chapter
When asked what his plans are for Christmas, Bang says he doesn't have plans and thinks of inviting Saitama over.

Bang, Who Is Too Overbearing
After witnessing Saitama's strength, Bang begins spying on him and Genos to better understand his power. Fearing that his martial arts style Water Stream Rock Smashing Fist would end with him, Bang decides to invite them to his dojo under the pretense of giving them free food. At the dojo, Bang demonstrates his style and challenges Saitama to some card-based memory games and rock-paper-scissors, with Bang winning almost every time. During one rock-paper-scissors match, an enraged Saitama nearly crushes Bang with a hammer, who is then forced to admit that Saitama is truly powerful. He does note, however, that the rock-paper-scissors game was the most excited he had ever seen Saitama be, and offers Saitama to join his dojo, but Saitama refuses.

The Murder Case That Is Too Impossible
Bang and the other S-Class heroes are invited to a hot spring resort after the Dark Matter Thieves failed invasion. While enjoying himself at the hot spring, Metal Bat voices his displeasure at how heroes that did not participate in the battle were invited to the resort too, but Bang manages to calm down the situation. The next day after the ceremony, the heroes find Zombieman murdered, stabbed in the back by Atomic Samurai's katana. As Child Emperor is investigating the murder, Bang is one of many that were still at the banquet hall and is ruled out as a suspect. When progress in the investigation halted indefinitely, Tatsumaki goes to restrain everyone, before Zombieman suddenly wakes up. Zombieman later reveals that Atomic Samurai's katana was floating with green light surrounding it similar to Tatsumaki's, when it stabbed him. Tatsumaki angrily denies this, but Bang manages to calm her down. Once everything is cleared up, the heroes then disband.

Going Fishing with Middle-Aged Men

Mumen Rider and Chain'n'toad soon appear, having chased a monster all the way to the lake. They fight the monster, Giant Salamander, while Bang and Kamikaze continue their conversation through the chaos. Eventually they decide to intervene, and Bang pulls Mumen Rider out of the water with his fishing rod while Kamikaze kills Giant Salamander and rescues Chain'n'toad. Bang then considers telling Kamikaze about Saitama's true strength, but decides to let him find out himself.
