You were Isekai'd from your old world via falling off a balcony and then your vision went black.
You had woken up as an Isekai to Twisted Wonderland, and slowly started to adapt to this world of magic and worship of the 'Great Seven', aka Disney villains that you knew back in your world, like; the Queen of Hearts, the King of Beasts, the Sea Witch, the Sorcerer of the Sands, the Fairest Queen, the King of the Underworld, and the Thorn Fairy. The Queen of Hearts was literally the only one who kept her original 'name', despite Disney not exactly giving her one.
Now, that didn’t exactly matter, what mattered was that you're now an empress of your own large, powerful content. As an Isekai, like any anome, you were luckily bestowed powers, powers that made you surpass everyone in Twisted Wonderland. Your powers also scared the other seven continents, which is what leads you to the situation you're in right now. You had been told that the parents of Seven Princes from each region are being sent to you as a way to keep an alliance with you, and your favor. If the princes simply lose favor with you, then they will be disowned.
Your self-made country had buildings based on China and Japan, a mix of the Ming Dynasty and a few others. You had basically copied what you remembered from this world and copied it into this one, but not exactly all of it, some of the stuff in that dynasty was old school. Which now leads to the present day, where you were sitting on your thrones with your royal advisors as they talked to you, until a eunuch came in, bowing in apology before announcing that the Seven Princes of each region have come and are here to be your consorts. Though, you already knew and were prepared with seven pavilions for them, since their parents sent you each a letter in advance, that doesn't mean you can't be shocked. It's not like you didn't know they were coming, their parents sent you letters in advance, and you just thought they were joking about giving their heirs off to you.
Your closest friend and advisor, Rakū, had luckily set up pavilions for each of the Seven Princes in advance, naming them; The Heart Pavilion, The Clawed Pavilion, The Coral Pavilion, The Sun Pavilion, The Poison Pavilion, The Phantom Pavilion, and lastly—The Dragon Pavilion. Before you can even say anything, your gyards had already opened the doors to show the very first of the Seven Princes come through the door, Riddle Roseheart, sole heir to the Roseheart name and the Queendom of Roses kingdom. Riddle has two, closest lords-in-waiting who are Trey Clover—his childhood friend, and Cater Diamond, with two servants below them named Ace Trappola and Deuce Spade.
The other princes soon follow after with their lords-in-waiting and servants, all dressed in their own color-coded outfits based on male kimono for royalty called, 'Kuromontsuki Haori Hakama', though the outfit is usually colored black, you decided to have them color-coded. Each of the other princes is mostly heir to their kingdoms, minus Leona, who is the second prince to Sunset Savanna.
The other Six Princes are Leona Kingscholar, second prince of Sunset Savanna, and twenty years old lion beastman with his lord-in-waiting, Ruggie Bucci, and bodyguard, Jack Howl. Azul Ashengrotto, sole heir to the Coral Sea and a seventeen-year-old octopus merman with two lords-in-waiting/bodyguards, Jade and Floyd Leech, twins moray eel merman. Kalim Al-Asim, sole heir to the Scalding Sands and age seventeen with his lord-in-waiting, bodyguard, and personal cook, Jamil Viper. Vil Schoenheit, sole heir of the Land of Pyroxene and eighteen-years-old with his two lords-in-waiting, Rook Hunt—who is also an acting bodyguard—and Epel Felmier. Idia Shroud, sole heir to the Island of Woe, and eighteen-years-old with his little brother, Ortho. And finally, Malleus Draconia, future king of Briar Valley—who had come to your kingdom on his own freewill—and age one-hundred-seventy-eight-year-old dragon fae with his lords-in-waiting and acting bodyguards, Lilia Vanrouge, Silver Vanrouge, and Sebek Zigvolt.
