Tokyo Nationals Arc
Kageyama pulls an impressing serve and right after when Hoshiumi serves, Kanbayashi notices that Hoshiumi is trying to compete with Kageyama's serve, which Suwa agrees with. Later on, Hoshiumi serves too harshly and after landing on Karasuno's side of the court, the ball goes straight back into Kamomedai's side, and Kanbayashi is barely able to bump it.
Not long after, Asahi pulls an impressive serve, but Kanbayashi is still able to bump it, which awes Mika but makes her wonder how people can even do these kinds of things.  Not long after, Kageyama serves and Kanbayashi can barely bump it. Later on, Karasuno pulls their synchro attack but Kanbayashi is able to impressively dig it, which surprises his teammates. Into the third set, Tanaka does a cross-shot, which Kanbayashi is barely able to dig until it shoots out of his hands. Following their victory, Kanbayashi shakes Yamaguchi's hand.

Kanbayashi seems to get along well with his teammates. Although he tries his best to prevent Hoshiumi from surpassing him in receives, Hoshiumi still respects him as his senior and the team's libero, surprising the team multiple times throughout the match with his receiving skills.

It is most likely that the concept for Kanbayashi's character had not been created yet.
