Reika's inner self has taken over and uses her corporate muscle to separate Shungo from Ryōko in an attempt to restore his memory. After reminiscing with Reika, he's drugged and held captive (plus nearly raped) in order to keep him from Mayu. Irori and Tasuku then combine forces with Shungo's other friends in an attempt to rescue him.
