I should structure the text as a continuation. Let's outline Chapter 20, highlighting the protagonist's struggle with the guilds, the climax of being disgraced, and then the transition to Takoku. For Chapter 21, focus on the slow life, potential character development, and hints at future conflicts or redemption.

In the next chapter, Kazuki’s efforts to forge a new identity clash with the world’s refusal to forget his past. While teaching a group of village children to bond with insects, a sudden goblin raid forces him to reveal his strength—but this time, not for war. Will the guilds notice his growing influence, or can a tamer find peace in the quiet corners of Takoku? Meanwhile, rumors of a rogue guild hunting “disgraced tamers” reach the mountains… and Yurei’s eyes flash with determination.

Make sure the text flows smoothly from chapter 20 to the preview of 21. Use appropriate chapter headers and maybe italicize certain terms for emphasis, though since it's a text to be created, formatting should follow standard practices without markdown. Check for grammar and clarity. Alright, time to put it all together.

The chapter opens with the protagonist, Kazuki, standing alone in the capital’s guild hall, his hands bound as the Royal Guild of Taming formally strips him of his rank and title. Once hailed as the nation’s strongest tamer, he’s now a pariah, accused of betraying the kingdom’s interests during a high-stakes territorial war against the rival Ember Kingdom. The council’s verdict is swift: his aggressive tactics, which saved countless lives, were deemed "a threat to diplomatic stability." The guilds, fearing his growing power, have turned their backs on him.

As Kazuki exits the hall, the streets are silent—former allies and townsfolk avoid his gaze. In a climactic flashback, readers witness the final battle where Kazuki’s tamed dragons decimated Ember forces but inadvertently scorched neutral villages, costing him political favor. The guilds spin the tragedy as his failure, leaving Kazuki with nothing but his tamed partner, a scarred wyvern named Yurei, who whispers, "We were fools to trust their guilds."

The chapter ends with Kazuki wandering into the remote mountain town of , a place forgotten by the kingdom. The villagers, wary at first, are swayed by Kazuki healing a child bitten by a poison fangbat. Here, he vows to live a humble life, tending to creatures that others fear—a turtle-beast with diamond scales, a shy crystal stag, and a mischievous slime. Yet, Yurei glowers at a distant shadow of a guild enforcer, hinting that the past won’t stay buried. Preview: Chapter 21 – "The Slow Life… Begins?"

Avoid any spoilers beyond the user's request. Since the user is looking to "read next chapter 21," the summary should end with a teaser for Chapter 21, prompting the reader to continue. Also, include some thematic elements like finding peace after conflict or redemption.
