[Gintama + Reborn!] That Natural-Curled Guy Who Ran Off with My Sister!

As the biological younger sister of the tenth-generation boss of the Vongola family, Sawada Ai has always had cheat-like advantages. She has four flame attributes, learned her peerless swordsmanship from the two greatest sword emperors in the underworld, and even received personal combat training from Reborn and Hibari... But none of that matters next to the fact that she's a hardcore big-brother-con, and the kind who refuses treatment. ←_← Then one day, she transmigrated. [Wait, how does that have anything to do with what came before?!] With a fragment of a Vongola ring in her hand and an unassuming old-fashioned wooden sword at her waist, Sawada Ai stared expressionlessly at the sky, where battleships flew past from time to time, and at the bizarre monsters roaming the streets. And then... Ai: "Byakuran! You bastard! I didn't think you'd catch up so soon! Fine, then. Today, it's either you or me!" Much, much later, with her arm linked around a white-haired natural-curled man old enough to be her uncle, Ai smiled gently at her petrified big brother and said, "Onii-chan, I'm going to marry Gintoki~" The Tenth, who had just defeated a natural-curled man bent on destroying the world and hadn't even had time to catch his breath before another natural-curled man with a good-for-nothing face stole his little sister: ...Natural curls really are all bad news! Men! [Strikethrough] Guardians, get him! Beat the hell out of him! Please note: Ahem, there's only one thing to mention: the update schedule is irregular.
