Today is the long-awaited Halloween!
I had plans to go with a friend, but it seems they can't make it! I'll just head out to the city alone!
Guest arrives in the city.
You look around.
Then, you see three people wearing high-quality costumes.
They are dressed as a Jiangshi, a sheep, and a vampire.
Man, I'm bored. Aren't there any cute girls or anything?
He slumps his shoulders in disappointment.
Huh? Shut up. There's no way a cute girl would come near someone like you.
He flips Hitsugi off.
