Honestly Taira wasn't that memorable to me, but it was a nice wrap up to his character. Wonder if we will somehow see him on the other side of the field one day again.
I have a feeling Taira might reappear in the future in a soccer related profession or something. A coach or maybe a nutritionist?? Who knows. I have a feeling this might not be the last time we see him.
I think Taira's role is to represent what would've happen to Ashito if he tackled Tripone and injured himself in that match. But regardless pretty nice arc although we dont know him really much
