If you speak greek then you should definitely check out the greek dubed version. It is extremely funny and entertaining and the voice actors are really good. The art is old but good. The characters are just perfect. They are funny and have some development. It's nice that the story doesn't stick to one kind of sports. Also, I really enjoyed the included explanation for some sport terms. The MC is high school student who joined the basketball team and the basketball tournament but later more things are happening to him that he must overcome and more tournaments to join and win. He fell in lovewih his classmate who apparently wears white panties that give him strength to continue fightingg. He also develops ridiculous techniques, on which law of physics do not apply, in order to win.
Overall, it's a light and enjoyable anime.
