Okay so this is a bit of a strange idea. I need someone to play Sesshomaru. Essentially this is the idea: Sesshomarus mother gets angry with him and casts a spell turning Sesshomaru to a mortal dog. She asks her favorite concubine to escort him from the castle and instead he casts him from the West and erects a magical barrier that he cannot cross. Alone and dying he is found by a woman from the future who takes care of him as his dog form.
