Lord Josef
"The appearance of that man spoiled our plans, but I hope we were useful." Otto bowed before Kyoya and spoke in Khloe's place. He was full of loyalty and pledged to serve Kyoya on his own.
Of course, Kyoya had never planned to use people, but these two were so useful for his concepts that he trapped them and fought on a daily basis.
This was exactly the reason why Otto had spoken like that, though.
It was just for a short time, but he and Kyoya fought together against lightning eagles. They weren't supporting each other, but Kyoya's presence was near. A lot of wonders happened then.
Otto's concept just oozed out smoothly. He could shift people's belief far easier and their techniques were as if waiting for his powers. The man knew that Kyoya was someone that could change his future!
Thus, he bowed and pledged.
