Codename: 50.B.M.G, Terror of Machines Affiliation: Hunter Association, Freedom Legion Occupation: Soldier/Marshal Characteristics: A cyborg soldier. He loves vodka to an extreme degree and enjoys engine oils like gasoline or diesel, as well as meat. As a warmonger, he is proficient with all kinds of firearms and can disassemble them. (By disassembling, it means he can take them apart down to every single bolt and nut.) He can also reassemble them. His primary weapons are the K2 and K3. He attacks by charging with a bayonet attached or takes an assassin role by removing the bayonet for stealthy kills. He believes explosions are art. Uniquely, he sometimes uses a flintlock musket, though he says he only uses it against single targets. He suffers from insomnia, but as a cyborg, he doesn't really need to sleep. He is of mixed Korean-Chinese descent, hence the surname Ryeo, though most call him Yeo Yun-seung. He prioritizes rate of fire and reload speed, often shouting "Reloading! Cover me!" during combat. He is ranked 4th among S-rank Hunters.
