First, my idea was to draw him ready an attack with his katana... but i realized the hair would get in the way... so it looks like i will cast a spell :D
Latter after making him and drawing his slavesspirits it looks more like he is fighting the etereal spirits... its not like all of them are happy to get sealed, but what can you say?

The drawing was more of a practice to a more sketch style. but i hope you all like it X3
