I Contracted Myself - Chapter 19 – Powerful canopy

In the Central 46 Compound, the Captain-Commander of the Gotei 13 and the notorious scourge of the Female Shinigami Association, Masatsuki Aozaki, stood before the Sages and Judges.“You have improper relationships with numerous members, Seated Officers, and Captains of the Seireitei?”“As Captain-Commander, maintaining close relationships with them helps facilitate my work.”“...”The Judge narrowed his eyes. “Then how do you explain modifying the female Shinigami's Shihakushō into miniskirts?”“To transform the Seireitei into a perfect paradise.”“Tsk tsk… A paradise for all Shinigami? That’s not entirely unreasonable…”“No, a personal paradise.”“A private—wait! Captain-Commander Masatsuki, that kind of thinking is clearly wrong!”“Do you want to die?”“...”“Forget it, Captain-Commander Masatsuki. We’ll set this matter aside for now. Let’s discuss some of the outrageous statements you’ve made in the past. Those were jokes, right?”“No, I was completely serious.”Masatsuki calmly ran his hand along the hilt of his Zanpakutō and spoke with conviction. “I have a great relationship with my subordinates, I get along well with Hueco Mundo, and I’m even friends with all of your wives and girlfriends. But rest assured, I’m a good Shinigami. You can safely leave the world in my hands!”Genryūsai Shigekuni Yamamoto: That damn brat! Shunsui, Jūshirō, don’t stop me—I need to teach him a lesson!Thus begins the tale of the most incorrigible Shinigami!

He became a teacher at the best magic academy in the empire.
….For being mistaken for someone else.

Saying 5000 year-old-dragon has an impressive ring to it, yet that dragon was an extremely harmless, herbivorous being. However, because of his uselessly giant figure and scary appearance, he was mistaken for the Demon King’s executive and provided by the nearby village with a sacrificial maiden.

Fundamentally cowardly and timid dragon tried to send her away, but the extremely enthusiastic sacrifice didn’t want to give up. Inevitably, he lied: “Okay, I just ate a small portion of your soul, so you can go back already”, but the maiden with outrageous assumptions has misunderstood that she became the dragon’s kin.

Then, out of all things, she began to manifest strange power on the basis of her wrong assumptions – in turn, the helpless dragon, by some mistake started a rebellion against the Demon King.

Rebellion or whatnot, he wasn’t even his subordinate in the first place.
