Synopsis
A meteorite fell near my city. At the suggestion of my classmate Wal (Wal because he does bad things), I decided to leave the house at midnight and go see it. Wal also invites Shiino, who doesn't come to school very often in a wheelchair, and is ready to go. A night picnic into the woods where meteorites have fallen. At this time, I was a little nervous because it was like an adventure that is common in manga. Without knowing that such a mysterious and scary event awaits in the woods. Suddenly, I remembered the strange secret word that was prevalent in the city and hummed. Meo Seo. Meo Seo.
