This is an anime that looks like it's from the early 2000 to 2010. The plot is about kids using small cars like insects to fight; they throw the cars on the ground and the fight starts.
I remember the main character wearing a red jacket and having a brunette and blonde hair. His best friend had purple/blue hair and had a blue car, and he had a heart problem. His other friend was kinda poor and worked in a restaurant with his family. He was also a little bit fat and blonde. The only female character I remember used to cover her face with a mask; her hair was blonde, but I think it was a wig. She was super poor, and can only feed her little brother and sister instant noodles.
The main character's car was a bug beetle; maybe it was a long-horned beetle, I don't remember. But I do remember it was red and had a name like Tonkat. And his special move was something like the golden burning blow.
Help me find this anime.
