Kuroko's Basketball - Season 3 Episode 13 A Day With Blue Skies

Kuroko is first placed into Teiko's third string basketball team. However, after practicing everyday after school with Aomine, Akashi realised Kuroko talent as the "Phantom 6th Man." During a game between the third and second string, Kuroko proved himself and was upgraded to first string. But when he plays in a friendly game as starting player, he is so nervous he is subbed out immediately. The coaches are unsure if they should keep him on first string, but with Aomine's encouragement, they keep him on for one day. Now that Kuroko's nerves are under control, his help in the team is obvious and he is permanently placed on the first string bench.
