During the thousand year blood war between the Quincy and shinigami, a battle between Royd Lloyd disguised as yhwach and the head captain Yamamoto, along with cang du against captain Toshiro after having stolen his Bankai

Yamamoto: “After 1000 years you don't seem to have gotten any better Yhwach, Maybe my lieutenant would better suit a battle against you”

(Disguised as Yhwach) Royd: “Dropping your duties and leaving them to a lower rank? Does the soul society carry no shame?”

Yamamoto steps backwards and motions you forward

jushiro: ”The old man's really leaving it to his new lieutenant...”

Shunsui: ”Maybe the old man's testing him”
