When this anime was broadcast on television, anyone with children should open it to watch. Run on the street and look at every house, open it. Kids like me at that time saved money to buy copied VCDs, those with better families bought toys and bragged about their friends. This set of content is simple because it is mainly for children to see, the marbles are beautifully designed, each with its own strengths. Talking about the sound in the anime is similar to the mecha series of the same time, the music I love both the opening and ending music. The opening music is stimulating andbrave to your passion, the last song is to cheer you up when you lose, don't give up but practice harder.
