Paradise Lost (パラダイスロストParadaisu Rosuto) is the twenty-second episode of the Golden Time anime series, which aired on March 13, 2014.
Stunned by Koko's words, Banri awaits Koko at the same spot he was rejected by her, hoping Koko would come back for him. Hours passed and Banri meets Koko's father, who drives Banri home. Along the way, Banri deduces that Koko may already had knowledge of Banri taking anti-anxiety medications and is asking her father of the diagnosis that leads to its prescription. Being dropped off, Banri encounters Nana, who Banri confides with for his recent dilemma. The next day, encouraged by Nana's words the other night, Banri plans to confront Koko. Afterwards, Banri is met by Koko, seemingly acting the same whenever the two interact. However, after meeting up with their friends, Koko nonchalantly declares that she and Banri had broken up, much to the shock and bewilderment of Banri and the others. After Koko lashes out on them, Chinami tells Banri that Koko may had seen the clip of Banri in his anxiety attack at his apartment from Chinami's camera the other night. Staying optimistic, Banri later informs Linda and the president of the Festival club of his breakup with Koko and is followed with Banri and Linda having a serious argument, in which Banri reveals to Mitsuo his past relationship with Linda and apologizes for not telling him. Koko then appears as she hands down a letter of resignation from the club to its president until Banri cuts her off, causing her to leave with Banri calling out to Koko.
