This one has kinda been poking me for a while but I haven't really been able to solidify the concept yet beyond the character serving as a foil to Muzaka.
Nicodemus: A dark elf necromancer that once ruled his guild like a king. When he got sucked into the game, he has decided to rebuild and this time try to rule anything he can get under his control. When he was in the other world (ours), he was a simple 9-5 office worker fed up with his job and ready to go postal. With no apparent restraints now, Nicodemus may have lost any semblance of sanity and strive to recreate his own personal dream world.
Like I said, still basically all concept. If yall got thoughts on him, I'd like to hear them.
