I Wish to See You, Ikuto
It's Tonkatsu's birthday and Suzu is preparing tofu. Later she and Ayane discover a photo which they believe is Ikuto's "lover" from his world. When Ikuto is discovered staring out at sea Ayane and the others all dress up to charm him. Suzu discovers that he has planned to leave the island and goes after Ikuto. He then tells her that it is his sister's birthday and that he was going to send a letter to her. Ikuto then helps Suzu with the tofu and everyone came to help celebrate Tonkatsu's birthday. During the end credits, a song by Tonkatsu replaces the usual ending theme, consisting only of "Pu"s. After the credits, Suzu helps Ikuto send off the letter in a bottle by encouraging him to throw it past the whirpools. Upon success, their relationship becomes noticeably stronger.

Nagasarete Airanto
After a terrible argument with his father, Ikuto makes a hasty, fateful decision to run away from home. Going from runaway to stowaway, Ikuto’s luck lands him on a ship heading right into the path of a huge storm! When it rains, it pours — or in Ikuto’s case, it pours so badly that he washes overboard and wakes up on a deserted island. Well, an almost deserted island. The island is populated by nothing but beautiful girls, all of whom want Ikuto to choose them as his bride.
