The old man Kuwabara felt "something" as he passed by Hikaru. He must of felt Sai's spirit. He even goes on to say that Hikaru is someone to remember. Ogata meets up with him before their match and he speaks about a new wave of players entering the world of Go. Then he says he wants to greet them as a titleholder, so he's going after Kuwabara with fangs bared.
Akira won the young lions tournament and he was promoted a rank. And now we got some new character at the end who plans to take the pro test. I wonder what role he'll have in the story.
