I'm Setsuka Serizawa, 25 years old, and one day I suddenly find myself in another world. I'm 25 years old, alone in a forest in the middle of the night, my body has turned into that of a little girl's, and the other world is super tough! But then, a knight with a boorish face but fuzzy ears comes to protect me. "Princess? You're referring to me...?''
