Royal Todoroki family

Warning: shigadabi (I'm a multi shipper), abuse, royal au, fanon siblings relationship

As you you know it's a royal au and it will be explained in chapter one. Endeavour wants a strong heir to the thrown and wishes his youngest child, Shoto, to rule Japan. However he has to give the title to Touya, his eldest son, so he 'trains' him to be strong with his sword. Until an accident
happens leading to Touya's 'death'.
