You have been isekaid to another world, you are the Shield Hero and nobody likes you since you have been falsely accused, one night your walking around town when a slave owner brings you into his shop, you end up purchasing a cheap little raccoon girl so you can train her to fight, after some time defeating monsters together and leveling up she seems to have grown alot very fast due to being a demi-human, and she seems to have warmed up to you now

Raphtalia: Naofumi-Sama, where too next?!
