Chapter 66

Have an affair is the sixth chapter of the eighth volume and the 66th chapter overall of the Tokyo卍Revengers manga series, written and illustrated by Ken Wakui.

Summary
Upon seeing Emma's affectionate embrace with Mikey, Takemichi is shocked, believing that if Draken saw this, it would lead to a conflict between him and Mikey that would cause the fracture of Toman, as Draken has shown clear romantic feelings for Emma. As he imagines the fight between Draken and Mikey, Hina suddenly pops up besides him, along with Naoto. Hina is determined to investigate the reason behind the affair, as she has recently been interested in detective novels; throughout her investigation, she references Sherlock Holmes frequently. Following Emma and Mikey, the three of them find them at a café, where they witness Emma feeding Mikey cake. According to Hina's intuition, Emma's eyes signify that she is in love with Mikey.

Suddenly, Yamagishi approaches the group, and they inform him of the current situation. Yamagishi says that he has heard rumors about Emma leaving Mikey's house with him, after she had stayed overnight. From this new information, Hina concludes that Emma is a two-timer; she drags Takemichi with her to confront Emma and Mikey. Takemichi protests, as he does not believe that confronting someone as strong as Mikey would be a good idea, but Hina tells him that she feels too bad for Draken. Suddenly, Draken appears, wondering what they are talking about, after hearing his name.

Hina slams her hands on Emma and Mikey's table, admonishing them of their actions. Unexpectedly, Draken laughs upon seeing the two, and teases Mikey for taking his little sister out for her birthday. Hina, Takemichi, and Yamagishi realize their mistake: Emma and Mikey are half-siblings. This also explains their resemblance, as well as why they left the same house. Emma says that she had already told Hina about this before, but evidently, Hina forgot this. For her birthday, Draken gives Emma a plush bear, which Mikey points out is the one she wanted at an arcade. As Draken leaves the cafe, Yamagishi, Takemichi, and Naoto marvel at Draken's coolness. Blushing, Emma happily hugs her plush bear, and Hina congratulates her.

Outside, Hina remarks that she has not seen Emma look that happy before, and hopes that things work out well with her and Draken. She tells Takemichi that she also hopes that things work out well with her and Takemichi. Grabbing her hand, Takemichi assures her they will, and the two of them happily run off, leaving Yamagishi and Naoto behind.
