The anime is based on a manga which I had read two years back and remember loving it, didn't remember the details so thought it was perfect time to watch the anime version. It's as good as the manga and totally faithful to it even the unique art is carried to the anime. The animation artwork is different from other shows in being more paint type, it's more cartoonist and at the same time very stylish, some may feel its low budget artwork but it's like that to add its one charm and pulls it off nicely. The artwork is beautiful and has intensity especially when the ping pong games are showcased. The use of pop up boxes and split screen adds to the charm.
The story seems simple but is in fact very deep, covers the adolescence age of the main characters, how different they are and how they cope with the world around them. There are lots of buried emotions which come pouring out as the series progress. Loved the way they drew parallels of stories between the supporting trainer characters and the main ones.
The sound and music is probably the best of its kind I have come across in an anime, the use of music for showing intensity or concentration, the intro music for Kong (the Chinese) it were all perfect, in fact they were able to make the noise of playing ping pong captivating.
The anime also has a bit humor along with the drama to keep things light. It teaches one life lesson, the importance and difference between talent, hard work & enjoyment at work. Would recommend it to any mature anime fans.
