Soraton (Matsudai Koya) is tormented by remorse after the incident with Hoshiai (Shimizu Naoya), when Nagumo (Tokito) appears before him and the pair head for Tenba's (Yusho) bar, Meteor. Nagumo, who has been conducting his own investigation, makes a proposal to Soraton, Tenba and Kanakaze (Kadoshita Shutaro) in order to uncover the truth behind the game. Meanwhile, Kagetsu (Toman) is pushing forward to realise her own dream, despite being bashed by the public. Then Azami (Kyoko Hinami) appears before Soraton again. Soraton is confused and conflicted by Azami's words. The fourth round was held in the midst of all this. Amou and Kanakaze challenge the overwhelmingly strong Hinata (Reiji). The curtain is cut on a gruelling battle.
