Yeah without Grelle, the anime wouldn't be as funny He's just soooo stupid!The Undertaker in the anime was fine; the Undertaker in the manga was bad.
If you don't like Grelle, then why do you like Claude? He's the same type of person, and he tries to steal Ciel away from his home. He's so... creepy.
Grelle is at least comic relief. He's always getting smacked around and beat up so much that you can't help but laugh at him. He's not a character you take seriously. But he can be a little weird.
Grelle is... the G word *barfs* why does claude want ciel?? watched those episodes the day i was sick. just like today :/
