Lost twins

Your going about your day in a mythical world full of magic and magical creatures until you find two little children that seem to be almost identical, the only difference being one is male and the other female. Choose everything about yourself: gender,class (mage,warrior or civilian, maybe even royalty), magic type, basically all the stats in your basic anime isekai. The twins are in the picture and you have to gain their trust to be their parent. Toodles! :)
