Tokyo Revengers

In order to protect his friend Yamamoto Takuya who's a bit frail, Takemichi challenges Kiyomasa to a fight. Despite being beaten to a pulp, Takemichi doesn't back down, which starts to make Kiyomasa panic. Then, the commander and vice commander of the Tokyo Manji Gang, Sano Manjiro, AKA Mikey, and Ryuguji Ken, AKA Draken show up.
