While he makes a bad first impression, he was a decent character on the show.
He first pretends to be an old man for no apparent reason.
And fights a very excited Kuwabara.
And like Shishiwakamaru, defeating him rather easily.
Just like his friend, he has to fight Genkai next.
And she makes a complete fool out of him.
I don’t know how he thought he could beat Toguro on his own.
He makes an unexpected appearance near the beginning of the final round.
Offering Kurama and Kuwabara weapons to help them win their matches as he hated Toguro so much.
He later joins the Demon World Tournament allying himself with Yusuke’s dream.
