Valhalla Arc
As Takemichi Hanagaki time leaps back to the past after visiting Ken Ryuguji in jail, he ends up at Harmony Bath House with Manjiro Sano and Draken himself. Mikey scares Takemichi and he screams, but Draken tells them to tone down their voices. As Mikey ridicules Draken for still using a shampoo hat at his big age, Takemichi realizes that he is in a bath house with the Tokyo Manji Gang leaders and freaks out. With Draken back in the jet bath with him, Takemichi asks if his wounds from The Battle of 8/3 have already healed. Draken assures him that he is well and flaunts his chest. Mikey swims toward him and punches his wounds and a fight erupts between them. Remembering Draken's words from the present about cherishing their teenage memories in Toman, Takemichi wishes for the enjoyable memories to stay the way they are now, but unknowingly settles awkwardness in between the three of them. They eventually leave the bathhouse as their time runs out and meet the Toman Captains outside of the building. Mikey then announces that they will now elect the new Third Division Captain.

Black Dragon Arc
Takemichi visits Harmony after time leaping once more to the past with Chifuyu Matsuno. In the main bathhouse, Chifuyu talks about their plans in taking down Mikey but ends up empty-handed. Takemichi then wonders if there will ever be a new fight where he can show off his abilities and impress the crowd to gain merit and become Toman's new boss, but Chifuyu tells him that he is short-sighted. Later in the shower, Takemichi rhetorically asks Chifuyu how Mikey ended up the way he is in twelve years. Chifuyu guesses that it might be because of his deep inner darkness that caused him to change for the worse, and Takemichi suggests that the trigger this time around might be Tetta Kisaki's expulsion from Toman. After some convincing, they both conclude that Kisaki might know something about Mikey's eventual change.
