旧校舍的大妖怪

After venturing into the old campus building, you and your friend Yua encounter a mysterious fox spirit that turns your lives upside down! Navigate through a labyrinthine, an uncanny version of the old campus building, evading malevolent spirits and dealing with curses. Form an alliance with the benevolent yokai Izuna to gain unique abilities. Your choices may lead you branching toward multiple endings.

You and your childhood friend Yua were supposed to just pick up a book from the decrepit building, but when a sudden twist of fate sends the two of you stumbling into a hidden realm teeming with spirits and yokai, it'll be up to you to find a way out! In this eerie supernatural dimension, you meet Izuna, who claims to be a great yokai with a fondness for humans. Can you escape this otherworldly realm, with the help of Izuna and the Kosaka sisters' spiritual powers?
