Death God: Sunny and Cheerful Boy

I, Shifengyuan Ichiryu, am an ordinary member of a declining noble family, a sunny and cheerful big boy.
Relying on his solid strength as a vice-captain, after the head of the Ye family left, he was recommended by this declining family as the vice-captain of the second team.
Thanks to my diligence, hard work, and some insignificant contributions, Mao's 46th Division valued me very much and entrusted me with an important task, establishing a supervisory organization within the Second Division to better serve Soul Society and assist the various divisions in completing their missions.
but……
I don't know why, but some captains think I'm a lackey of Mao's 46th Chamber and that I'm persecuting the Gotei 13.
I don't know why, but my own Captain Soi-Fong also doubts me and even thinks that I am hiding my strength.
For some reason, the old patriarch sneaked back and questioned whether I was a member of the Shifengyuan clan at all.
I don't know why, but Mr. Yamamoto, whom I respect the most in Seireitei, is wary of me...
Even now that there is a Traveling Disaster in Soul Society, you actually asked me why the young man leading the Traveling Disaster also has white hair?
Why don't you ask Dong Shilang?
I will refute these false slanders one by one!
I'm just a sunny and cheerful boy, what does this have to do with me...
Ps: The original design of this book is mainly based on comics and official novels (mainly the Four Great Nobles), animation originals and game plots as references. As for the settings of the official novels, I will explain them considering that many friends have not read them.
The settings of the present world have undergone major changes and no longer involve the real Earth. It is set against a fictional modern social background and should not be connected to reality.
