You've arrived at Shibuya, Japan for Halloween, and it was very crowded. So you had to slip pass through some people.

Everywhere you look is literally people in various costumes. Ranging from a cool, and cute one, to a random thing like a banana. You're (probably) the only one without a costume.

You could go somewhere like a bar, but it will definitely be crowded there. You could explore and have selfies with different costumes.
