If I had to pick one particularly memorable character from Iron-Blooded Orphans, it would have to be Hashmal!!!
Putting aside the comedic impression of the Commander and the Peshan gang,
while the main mechs, including the protagonist's, all bear the names of demons, this one suddenly appears with the name of an angel.
And what's more, it's a killing machine despite its angelic name 😱
With its claws, tail, and beam, it's a vicious machine that wreaks havoc, yet it has a white, wing-like form. It's a beautiful yet eerie design. This beam didn't do much damage to the mech or the main characters, but it's a weapon full of murderous intent that incinerates everything around it... When I first saw these guys in the anime...
