An incident causes Yutaro's soul to leave his body. As he searches Koraikan for a way home, he catches a glimpse of the female tenants' panties, leading to unspeakable disaster on earth! Why?!
So, Iridatsu Yu-tan, your soul has left your body.
Wie du siehst, Iridatsu Yuu-tan,
hat deine Seele deinen Körper verlassen!
Y así, Yu-tan Iridatsu, 
tu alma dejó tu cuerpo.
Y así, Yu-tan Iridatsu, 
tu alma ha dejado tu cuerpo.
Et voilà comment tu t’es retrouvé
hors de ton corps, Yûta Iridatsu.
Insomma, per farla breve, Iridatsu Yu-tan,
la tua anima si è separata dal corpo.
Então, Iridatsu Yuu-tan, 
sua alma deixou seu corpo.
