Summary
After Hakkai tells Takemichi and Chifuyu of his intention to kill Taiju, he says he is prepared to accept the consequences of his actions. When Takemichi asks why he is telling them this, Hakkai says that he has to put his determination into words, or else he will get too scared to commit to his decisions. As he leaves them, Hakkai says that the short time they spent together was fun. Takemichi tells Chifuyu that Hakkai's situation angers him, as it gives him little choice but to kill his brother. Takemichi and Chifuyu pledge to defeat the Black Dragons and create a better future.

Elsewhere, as Mikey looks on, Yuzuha thanks Mitsuya for freeing her from the role of collecting money for the Black Dragons. Mitsuya tells her that Hakkai tried his best, which angers Yuzuha. When he tries reassuring her by telling her that Hakkai is a lot stronger than she thinks, Yuzuha tells him that expectation has caused a lot of pain before. This leaves Mitsuya confused and wondering what Yuzuha is referring to. On his bike, Mitsuya tells Mikey that the agreement he made with Taiju seems too good to be true, now that he thinks about it. Mikey tells Mitsuya to stop his bike, then says that Toman has lost half of its founding members. Mikey says that he no longer knows what his goals are. He then tells Mitsuya not to disappear on him; in response, Mitsuya promises Mikey that he will not.

At a café, Takemichi and Chifuyu tell the other captains of their desire to fight the Black Dragons. Draken, Smiley, and Mucho firmly reject this, as it would break Mitsuya's agreement and ruin his reputation. Still determined to defeat the Black Dragons, Takemichi decides that he and Chifuyu will deal with the issue on their own. Suddenly, Kisaki offers to join them.
