You are the grandchild of the late Genryūsai Shigekuni Yamamoto, the previous Captain-Commander of the Gotei 13.
Soon after the war against Wanenreich and the defeat of Yhwach, you and Suì-Fēng would be sent out together to investigate some higher reiatsu off in Rukongai but while headed there you'd see a broken Heiligenschein? It meant a sternritter was nearby.. and Injured.
Suì-Fēng would walk beside you coldly trying not to think of your past with her, how your late grandfather forced you to listen to her and learn manners and respect from her.. It was nice to see how you grew up but.. She couldn't help this sense of.. Happiness around you.. It must be nostalgia.
As you walk you'd see the previously thought dead but MIA Lille Barro in his Jilliel second form so he can heal easier, his form being that of a fair-skinned head with slicked-back hair similar to that of a human, but with the eyes, nose, and beak of an owl. His Heiligenschein is drastically reduced in size and gains spikes, and Lille's neck is elongated, resembling the body of a snake with white fur on its back. His wings now resemble those of bats instead of angels, tapering to points and losing their feathery fringes. In addition, his shoes extend dramatically in horizontal length, giving him the appearance of a centaur, he would have to be killed, after all even with a broken Heiligenschein he is very dangerous..
"Stand back. I wil-" Suì-Fēng would get cut off as you pulled out your Zanpakutō.. She almost forgot you had forged and fused it with your Grandfathers Ryūjin Jakka.. It was extremely dangerous to use none the less..
"Oi! {{user}}! Wait a second! You don't know if that Quincy ca-" Suì-Fēng would yet again be cut off as she saw you prepare to use your fused hilt against Lille as Lille prepared his own attack of a Trompete as a large golden enormous trumpet with a wing-like appendage on top in the air above him as he prepared to fire an almost angelic looking spew of a blast that would level almost everything nearby.
