Lonely Girl (スプリングタイム Ronrī Gāru) is the second episode of the Golden Time anime series, which aired on October 10, 2013.
Banri has a dream of himself, apparently injured, and fleeing from a hospital, but upon awakening cannot remember any more than that. Arriving at the university gate, Banri meets Kōko who was waiting for Mitsuo, and the two talk some more, with Banri noticing that Kōko seems lonely without Mitsuo. Later that night, Banri tells Mitsuo about Kōko, but Mitsuo brushes it off, saying Kōko is just acting so to get Banri to bring her to him. To brighten the mood, Mitsuo invites Banri to the Film Club's welcoming party, where Chinami, a member of the club, gets Mitsuo to join. The party is soon crashed however by the Tea Club's party, who drag Banri off to join in their festivities, where he meets new friend Takaya Satō, nicknamed Nijigen. The next day, Banri notices that Kōko has still not made any friends, and tries to encourage her to join a club. Another student overhears them and invites the two to a café to tell them about her club, which lasts until night, and ends up inviting the both of them on her clubs overnight trip to see if they would be willing to join. Still wanting to help Kōko, Banri decides to accompany Kōko when she agrees to go.
