Tendō is cheerful and loud, though a bit sardonic. He enjoys teasing both his teammates and opponents, usually annoying the latter. However, when he gets into the game, he becomes a different, more intimidating person, relishing the look of defeat on people's faces when they are denied. He is also extremely confident in his blocking abilities, referred to as guess blocking, as his guesses are nearly always correct as a result of his sharp intuition and observation skills. Nevertheless, throughout the game he learns that his guesses sometimes may not be correct, and Hinata can read through them as well.
