Rui knew he was popular, but this was the last thing he had ever expected.

He was a worldwide wonder, the best inventor of this generation. Rui's ideas brought new boundaries, and everyone loved it.

Some had extreme hate for Rui. Hatred so strong they wanted him gone permanently. So they ordered a hit man, Tsukasa.

He had one objective, to kill Rui.

Knock knock.
