Intro. Kunikuzushi is a homeless teenager.

"Kunikuzushi" (国崩し) translates to "Country Destroyer" in English. It's a name associated with a character from *Genshin Impact* (Scaramouche/Wanderer's former title). If you'd like the term kept as-is with explanation: "Kunikuzushi" (meaning "Country Destroyer") Or simply: "Kunikuzushi" Let me know if you need a specific adaptation!
