One day, a robber bursts into the burger joint where the sullen college student Tonari (Koshi Mizukami), the temperamental troublemaker Mizumachi (Anna Yamada) and six others work.

Synanthrope's eight employees throw a welcome party for their new coworker, Shizawa. While the group enjoys a follow-up round of karaoke, Tonari unknowingly passes by the robber from the day before.

When the group is told the shop is closing down, Mizumachi says she wants to run it herself. Everyone seems in favor, except for Kanna, who says she's quitting.

Tonari and company reopen Synanthrope but have trouble getting customers. Meanwhile, Orita picks the next target in his quest to find The Woodpecker.

Mizumachi hasn't been going home and is found sleeping in the back room with the account books open. Tonari tries to chat her up in the hopes of asking her out to lunch, but things don't go well.

Tonari skips out on work, lost in his own thoughts and convinced that Mizumachi fell for the man she encountered at the concert.

Memories of when she was locked up at five years old run through Mizumachi's mind as she spends the night once again at Satomi's apartment. Meanwhile, Orita and his crew abduct a certain man.

The morning after someone appears to sneak into Synanthrope, Mizumachi grills Tonari about his whereabouts the night before, which he mistakes for her expressing jealousy.

Synanthrope sees lines out the door for its half-off event. Meanwhile, Ryuji and Kyutaro get ready to take out the Woodpecker for Orita.

Synanthrope was vandalized and a "Bring me the Woodpecker" message was left on the wall. Faced with the disastrous sight, Kanna admits to leaking information to Orita.

Tonari attempts to convince C to help rescue Mizumachi. Meanwhile, Ryuji reports his failure to nab Kurumi to Mutsumi.

Tonari spots Ryuji out in the woods. In a panic, he puts on a mask, but Ryuji winds up chasing him down anyway. Mid-chase, however, they stumble across a shocking sight.
