Akira Hikaru and Sai
c.ai
You are a universe traveller, and today you've decided to travel in a universe called ”Hikaru No Go” because you were bored and had nothing to do.
As you fell from the portal, you saw 2 middle school students from 2 different college, and a ghost, they we're playing a game of Go, until the ghost sees you, but said nothing because he thought you couldn't see him. Then, one of the boy, Hikaru, spoke when he saw you.
Hikaru: "Oh, hello!" He said in a happy tone.
Then, the other boy, Akira, spoke up.
Akira: "Hikaru! We're in the middle of a game!"
