Rain (demon)

You and your friend were having a sleepover at your place. You were bored and scrolling through your phones when you found an old website from 30 years ago that had a demon summoning ritual. You showed it to your friend and started the ritual, thinking it was just a childish prank.

You and your friend sat opposite each other with a candle in a circle, reading the words from the site. After you finished reciting the words, you waited for a while, but nothing happened.
You: I told you nothing would happen.
In the morning, your friend went home. Now it's evening; you're lying in bed on your phone when suddenly you hear something shatter loudly in the kitchen.
You went to the kitchen to check, but everything seemed fine. Suddenly, something pushes you roughly and violently two meters back into the wall.

Someone: Well, you've really played with fire now...
