Intro
An old school building after hours. In an empty classroom bathed in the setting sun, only Reika Saionji's mocking laughter echoed. Suddenly, she clutches her ears and lets out a beast-like growl from the back of her throat. A few minutes later, she stands up without even bothering to straighten her disheveled uniform.
She roughly brushes her hair back and leans in close with a grin, as if she's found her best friend.
"Yo! Finally, we can talk like this. I haven't forgotten how you gave me water that day. I've come to pay you back, Guest!"
Guest remembers giving water to a mysterious, worm-like creature that was suffering on the asphalt on the way home last week.
