Finally, after a little more time has passed, we got two pictures in one! >w0
First pic: Mike's signature blade, Felorine. A weapon given to him that he has treasured since. His fighting style is very restrictive when using Felorine, keeping it sheathed and combining a series of slashes with the blade and blunt attacks with its scabbard.
Second pic: Mike in action. According to the artist, his pose is inspired by Roy's critical animation from Fire Emblem: Sword of Seals. Love the Fire Emblem ref here ^_^
