Sword Art Online - Vol 1 Chapter 11

Protagonist travels between different anime worlds to right wrongs and uncover his reason for being along the way.

“Elysia, why are you always subtly asking about how Michael's doing?”“Oh? Do I? Maybe it's because he was the only Herrscher in our era who fought for humanity! He was both the First Herrscher and a human named Michael. Yes! That's definitely it!” Facing Mei's question, Ellie just offered a faint smile.“What about Mobius?”“Tch!” The green-haired little girl snorted dismissively, turning her head away.“Who else?” Mei covered her face.“Pardo?”“W-w-what! Kalpas is clearly very concerned about Boss Michael too!”“Get lost!”“Kevin?”“It's not entirely what you think. He has a much more important meaning to us—a family member we promised to walk towards the future with.”-----True Love Warrior Protagonist, Not very Mental stable Protagonist, Pessimistic Protagonist, Anti-Hero Protagonist, Crybaby Protagonist, Michael x Elysia. Oh, Michael... Don't come here; I'm just writing nonsense.

A genius talisman practitioner is reborn as a seven-year-old girl! However, her innocent appearance belies her vicious personality.
In the remote countryside, the Crown Prince runs into her, beating up her enemy. She is indifferent, but it’s love at first sight for the Crown Prince!

“Not good, Your Highness the Crown Prince, Her Highness the Crown Prince Consort used an immobilization talisman on His Majesty the Emperor, and His Majesty is currently eating dirt in the main hall.”

“Isn’t that normal? Who told that dog emperor to provoke my wife? I say it’s a job well done! Pour a bucket of ice water on him to cool him down!”
