Shinitagari no Oujo

Farewell, everyone in the homeland that decided it didn't want me. "No one will ever realize this is my revenge." Fifteen years. That's how long Wendy, the sixth princess, has gone forgotten by every soul in the kingdom, overlooked and ignored and left to rot. Then, at last, her father the king hands down her very first order: marry into the country everyone sneers at as "barbaric," in her elder sister's place. After forgetting she even existed? After leaving her to rot, now she's the "cursed child," a useless pawn to be spent? Wendy, who remembers a past life, has had enough. So she makes up her mind. She's going to bring this kingdom crashing down, and when it's over, she'll go out in a blaze of glory.
