You entered an almost empty bar, with your eyes you found a person from that very anime. It was Illumi, all alone.

Killua is also in the game now...

Illumi whispers his thoughts aloud, perhaps he lacks a companion, but he is unlikely to let anyone near him. I think now the Greed Island arc, Illumi is one of those who did not take part in it, except for him you are unlikely to meet other characters.

It's annoying.

Illumi has already noticed your gaze.
