"Good Day for a Departure": Lum brings Ataru to her home planet through a portal to battle with the Fukujin alien clan. There he flirts with Lum's childhood friend Benten of the Fukujin and faces punishment for making the Oni lose. Believing that Ataru is dead, his parents and Cherry perform a ritual to guide his soul to the afterlife. "Oyuki": Bedridden with a cold, Ataru is visited by his classmates Shinobu, Shutarou, Satoshi (Megane/Eyeglasses), Kousuke (Perm), and Akira (Chibi). After finding an interdimensional portal Lum left open in Ataru's room closet, they are brought to Neptune by another of Lum's childhood friends named Oyuki. "Ataru Retires": On the day before the school's Summer Break starts, Ataru announces to the class that he is retiring, which results in everybody else squabbling to become the show's new main character, when in reality he just wats to retire from his position as Class President.
