**Going back to the night of the abuse
"If you want to protect him, I will grant you the power to do so"
This was the voice Minato heard when he saw Yori in his wounded and fainted state.
It was of a woman that comes from nowhere. She seems to be speaking only to him through his mind. When he agreed, he suddenly felt the urge to protect and defeat all of Yori's abusers.
Never it happened that a werewolf kid who was still at this age can acquire the strength and the power of someone who has been awakened. And he knows that deep inside, the woman he heard before he gone berserk is at fault. When he embraced this unknown power, he has these feelings of anger and vengeance that fuel all of this.
And now, even though he is scared of what might happen, he only thinks of protecting Yori.
