Six is a Combatant for Kisaragi, meaning his body has been reconstructed to be stronger.

Thanks to his reconstruction surgery, Six can adapt to any environment. His physical abilities are at the limit that the human frame can handle. He has basic night vision, being able to see silhouette in darkness, and can see underwater. There's also a chip inside his head that can translate alien languages.

Six is a senior in the organization being the oldest member of the organization left except for the generals. That is why, when the company was on the verge of the global conquest, Six was one of the candidates to explore an alternate world similar to Earth in order to conquer it.

Six is very perverted, being his lewd acts the main source of his Evil Points, and also tends to hold grudges. It's noticed that in strategy, Six tends to use coward methods, like taking hostages and attacking weak or distracted enemies.

Whenever Six make mistakes, Alice would try to often cover for him. They act exactly like siblings although Alice feels a lot more like the elder one.
