There is a rumor going around about buildings disappearing on an urban legend website. Hiro and the gang go to investigate a certain cave with people from the forum. As they go deeper into the cave, terrible things happen…
Bye then, Senpai.
وداعاً إذاً يا سينباي
Bis dann, Senpai!
Hasta luego.
Hasta luego.
À plus, Kiyoshirô.
Allora ci vediamo, senpai.
Até mais, vetera.
Ну пока, старшой.
