An Oddette's Otherworld Odyssey

An Oddette's Otherworld Odyssey summary:

A heroine character that transmigrates with a favorability rating system is busy raising love flags. A villainess character transmigrates in and is busy preparing for her counterattack. Then what is the third random transmigratee, holding a divine sword in her left and a steamed bun in her right, doing? “Please marry me!” The girl says earnestly to the beautiful blond boy. Ming Xi: … Answer: She’s busy proposing. A hilarious story about an overpowered airhead in a world reminiscent of Coiling Dragon. This particular tale has an interesting mash of tropes (As you might see from the summary).
