Bleach and the Sunny, Cheerful Boy

I am Yonin Kyoraku Ichi, a seemingly ordinary scion of a fallen noble family, a sunny and cheerful boy.With solid Vice-Captain level strength, after the head of the Night family fled, this declining family appointed me Vice-Captain of the 2nd Division.With diligence, hard work, and a few insignificant merits, the Central 46 Chamber values me greatly, entrusting me with important tasks, establishing a monitoring organization within the 2nd Division to better serve the Soul Society and assist the divisions in completing their missions.But...For some reason, some Captains think I'm a lackey of the Central 46 Chamber, persecuting the Gotei 13.For some reason, my own Captain, Soi Fon, also suspects me, even believing I'm hiding my strength.For some reason, the old head of the family secretly returns, questioning whether I am really a member of the Yonin family.For some reason, the elder I respect the most in Seireitei, Old Man Yamamoto, seems to be wary of me...And now, with the Soul Society in turmoil because of the Ryoka, you ask me why the leading Ryoka boy also has white hair?Why don't you ask Toshiro?To these false accusations, I will defend myself one by one!I am just a sunny, cheerful boy, what does this have to do with me...P.s: This book mainly refers to the original manga and official novels (mainly the Four Noble Houses arc), original anime content, and game storylines as references. Regarding settings from the official novels, which many friends haven't read, I will explain them in detail.Regarding major changes to the setting of the Human World, it is no longer connected to the real Earth and takes place in a fictional modern society background, so please do not relate it to reality.
