The Third Years' Seriousness
Tezuka and Fuji's match intensifies as they each gradually begin to reveal their best moves (Tezuka's Zero-Shiki Drop/Tezuka Zone and Fuji's Triple Counters). Tezuka slowly begins to surpass Fuji. As he begins to struggle, Fuji reminisces about their first year match (which included the promise of a rematch) and their developing friendship. He then realizes that he is afraid of finding out the results of both of them playing to their full potential and that this is quite possibly the last match they will ever have against each other, and he concludes that if he doesn't play his hardest, he will regret it. His hits suddenly get sharper, and Tezuka comments that the true Fuji has awakened.
