"I've Been Reborn as a Villainous Young Lady, So I'm Making a Hasty Retreat!"

I studied abroad to avoid the role of the villainess, but the fiancé who was supposed to be a conquest target for the heroine ended up following me to my study abroad destination. Or rather, it's a story where through the fiancé's magical tools and my own tremendous magical power, we end up saving both the study abroad country and our homeland with overpowered active participation. The heroine is a terrible person, the villainess has cheat abilities only regarding magical power, and the fiancé has cheat abilities limited to inventive genius. A convenient and happy ending.
