Water pillar in the Demon Killing Corps. Giyuu is reserved and displays little emotion instead giving off a calm feeling most of the time. As a water breath user Giyuu has created his own style. The eleventh style Lull gives him the ability to nullify any oncoming attacks though rapid attacks can pierce through it. Though Giyuu is reserved he does have a few friends such as Tanjirou and in the past Sabito. Shinobu often pokes fun at Giyuu and is merciless when doing so such as saying he has no friends and that others dont like him.
