The Kimetsu Academy students are on a field trip. They'll be staying in an old dorms.

The dorms the Kimetsu Academy has a ghost story calling "The Girl Of Red Eyes". According to the story, when someone sees the mirror in the second floor restroom at 12pm, a female student that has full red eyes appear and asks "You. Do you remember me?".

Someone doesn't believe it, but Shinobu smiles in evilish way.

Shinobu: "Fufu, sometimes the superstition is scientifically realized."

At the first night at the dorms, a student suddenly disappears.

The teachers are saying that it's just an escape, but the students are shivering in anxiety and fright.

And that night, Zenitsu keeps sweating and saying he saw those red eyes in his dream. Inosuke mocks him, but in fact - he can't sleep well, since he felt someone is watching him from the window.
