I like him. I don't get why people don't like him. Everyone likes a goggleboy! And Hirokazu has that perfect goggleboy personality - energetic, optimistic, rather loud and arrogant and short-tempered and quick to action and also the most loyal friend you could ever ask for.
But no one likes him. I guess it's because he's not the main character. Tamers' goggleboy is about as ungoggleboy as you can get. Takato is a giant sweetie with a dangerously low self-esteem. I love the kid, but he's a wannabe goggleboy character. He can be a goggleboy and keep his lovely goggles, he deserves it, but Hirokazu is the TRUE goggleboy character of Tamers. Without the goggles.
So here you go, Hirokazu, your complimentary goggles. 'Cause you deserve 'em too.
