The Duchy Princess has a cheeky personality

After being ruthlessly murdered by my stepbrother and sister, I woke up in another world as... a baby?!!

Even I can't pass on, I have to live as someone else now. And what's worse; I'm once again an illegitimate offspring of a duke's son, only this time I'm the villainess Rosalia Del Aviv Fontaine who was ruthlessly killed by her entire family after attempting to poison her grandfather and the "real" daughter of the duke's son.

Now I must find a way to survive, which means I have to grow old enough to leave this house... and to avoid the duchy family at all cost.
