Between Crimson Skies
A famous Kuni Oni slayer. He was friends with Hiruma Usigo when he was younger. He found him the morning of the raid on the castle covered in blood and crying. The man had no memory of what happened, he could only wisper one name and that was Asako Takomuri. He owed his friend his life many times over and decided to cover it up. He cleansed the area of all spirits and then changed the journal of the Asako to make it look like he was dark in his nature. He has stated that if we ever make the knowledge of this cover up happen then he is coming back to us.
