He has blonde hair, and wears a red suit when he is on TV.

He looks flashy, but people say "he has "Uunique creativity", "Ahe has a consistent personality",

The later quotes can't take "has" but putting "has" outside the quotes implies the "has" belongs to all the quotes. So instead I moved the "has" into the quotes.

This kind of quoting of phrases is only used when you're describing other people's thoughts or descriptions, so it's more natural to say "people say", which is a bit like という in Japanese.

"His knowledge and a vocabulary are in a different league", "Reading amount is really great as wellHe's very well read".

So, he is really smart and is called a “intellectual comedian" in Japan.

He is thea quiz shows host and as commentator on TV, he breaks the ice with ahis calm aurapresence, and he's smart without being sarcastic.

"he is the quiz shows" is like saying the quiz show and the presenter are the same thing.

"aura" is not used that much in English.

And he says clearly that if he doesn’t know something, he just clearly says “I don’t know.”

It sounds better to eliminate the repetition of "he says"

So, I love the Japanese comedian Kazlaser.
