After-school Vacation (放課後のバカンス Hōkago no bakansu?) is the fifteenth chapter of the spin-off Houkago Shounen Hanako-kun.
Summary[]
Hanako, Nene, and Kou go to the beach in the netherworld. When they get there, Kou asks Hanako why he would bring them to the beach. Hanako replies that they worked so hard, they deserve a break and that swimsuits look cute and sexy. He presents three mokke dressed up as Yako, Tsuchigomori, and Akane, telling them to pretend at them in spirit. He originally invited them to come with him, unfortunately, they all declined. After this explanation, they continued to do other activities throughout the trip.
During this, Natsuhiko is monologuing to himself on the beach about himself and how Sakura didn't come with them. It shortly gets interrupted by Mitsuba telling Natsuhiko that Tsukasa is swimming to Los Angeles, to which Natsuhiko quickly dives into the ocean to retrieve the troublemaker.
Later, Nene is seen holding a bat, blindfolded in front of a watermelon. As she is swinging the bat, Hanako yells in random directions. This gets Kou to question Hanako's quips, to which Hanako tells him that if Nene breaks the watermelon, they have to leave. Right after his sentence, Hanako gets a hit by a bat on top of his head from Nene. She gets excited thinking that she hit the watermelon as intended, only to see Hanako unconscious. They ended up leaving because of this.
