I, Kiana Kaslana, Am Invincible!

Punched into another world by cosmic forces, a hapless soul awakens as Kiana Kaslana—the Herrscher of the End with godlike powers. After reclaiming her apocalyptic might, she joins a mysterious chat group and embarks on a multiverse-spanning quest to save collapsing worlds. From bestowing humanity the gift of reaching for the stars to crushing divine entities bent on extinction, Kiana's invincible journey crosses Demon Slayer, Mieruko-chan, and beyond. No male lead. Pure overpowered heroine action across infinite anime realms.
