dose you guys know who he is and which anime he in

Alexander Nikolaevich Hell from The Qwaser of Stigmata

no sorry but it kinda looks like Allen Walker form D. Grayman

D-gray man; main character

edit, I actually kind of take that back because they are not exact copies, but that character would be to be a fan-based exaggeration of said character

Sasha from Seikon no Qwaser ;p
