Kishimoto (Kaio's first board) played a match with Hikaru to find out his real strength and expressed his puzzlement as to why Akira sees Hikaru as a opponent when he's not as strong. Through Kishimoto, Hikaru realises the widening gap between Aikaru and himself and that it would be impossible to catch up with Akaru with Hikaru's current pace. All fired up, Hikaru decides to start off with enroling in the Insei program with becoming a Pro and defeating Aikra as his goal. However, he failed to realise that Inseis can't participate in Amateur tournaments. Thus, he's being forced to make a choice between being a Insei or quitting Haze Jr's Go Club. (thetvdb.com)
