About 9-10 years ago, I read a Prince of Tennis volume(Chinese translation) at my cousin's room in China. It had Tezuka vs Atobe game.
Many years later I was searching movies at asiatorrents. There I saw Prince of tennis live action & downloaded it. The movie wasn't actually good but I liked Tezuka Zone & Zero-shiki drop shot. Later I checked out the anime & liked it. And then read the manga. I didn't read PoT manga thoroughly. I skipped a lot of pages. Then read NPoT manga & watched the anime.
I started to watch the anime just to see some cool techniques and slowly got addicted to it. What I like about it is the way Konomi-sensei develop techniques & install it to characters.
This video probably got my interested at some point as well
I meet PoT watch on channel of anime Animax!!!!!
