Punch Line

High school student Yūta Iridatsu finds his spirit separated from his body in a phenomenon called "astral projection." He awakens in a mansion called Koraikan, where a cat spirit named Chiranosuke informs him, "To return to your body, you must locate the Sacred Tome of Koraikan." As Yūta explores the mansion's halls, he accidentally runs into the underwear of its female residents-an act that, well, might just cause major problems for Earth itself.
