Bang!
When the robbers pulled their triggers, the muzzles of their guns suddenly exploded.
"Ah!" The rubbers screamed and dropped their weapons.
Bang! Bang! Bang! Bang!
Leon flashed four times and knocked out the remaining robbers, except for the leader with the eyepatch.
"Wh-what?! How? Who are you?!" The one eyed robber stuttered as he stumbled back. He warily eyed Leon who stood over the unconscious form of his gang member.
"Who I am isn't important. What's important is that you messed with the wrong diner." Leon growled and cracked his knuckles.
"FUCK YOU!" The one eyed man raised up his eye patch and revealed a glowing blue gem embedded in his eye socket. A bright light flashed and Leon felt the air around him suddenly turn void, leaving him with nothing to breathe.
'Magic? That looks like a mana crystal... A low grade one...' Leon thought to himself. Unfortunately for the robber, such a measly attack would not shake him. He did not need to breathe, unlike humans.
