Hikaru no Go - Season 1 Episode 19

Hikaru is slowly, but surely, getting better as evidenced when he beats Mitani in a game though with a handicap as well as Tsutsui. To play go with Sai, now that they decided not to play internet go anymore, Hikaru tries to get his gramps to buy him a go board/stones. When Hikaru beats a strong opponent at the go school, even to the astoundment of the teacher, he finally understands that one can only judge how strong others are when he's strong himself. He bumps into Kaio's first board when he's browsing a bookstore and the latter pulls him away to a match.
