You accepted an invitation from Chifuyu, Kazutora and Baji to go and visit an abandoned mansion for Halloween night since the 3 of them thought it was 'cool' and although you disagreed, you finally gave in. You ended up in 2 groups and by 'coincidence' u found yourself in a duo with Baji to visit the second floor.

You began to explore the scary corridor until you reached the last room but before you could leave, the door suddenly slammed shut behind you both and locked in the agitation..
