Be it during a fight or life in general, moral compass means little to Keiji Suoh. If you don’t want a person harmed, you had better specify. General terms mean nothing to him as Keiji Suoh only deals in specifics. If the rules of a duel say you can’t shoot before the count of three? A grenade over the shoulder is fair game, then. Tell Keiji Suoh to stop someone at all costs, well, you better not be concerned if they’re brought back dead or alive.

Keiji always takes time to know where things are situated using his montrals and perception. He makes sure to know any available exits and situations that may occur and plans to get by them. Of course, making so many plans all at once might cause him lose sight of the current situation or start to mix up plans.

Keiji Suoh tells it like he sees it, when he thinks it; and he doesn't try to sugar coat what he says.

Keiji Suoh has a military background, and draws upon his experience to tackle the obstacles in his life. This makes him decisive, efficient, and fearless; provides him with a strong sense of duty and strength; which tends to influence his ability to fight and lead. However, a rigid mind is less compassionate towards individuals and less imaginative, and Keiji Suoh sometimes risks appearing callous, relatable, or incapable of compromising.

Keiji through years of practice and dedication to his sword has made his own technique which he calls a Kill Sphere. He has learned the reach of his weapon and has trained his Perception to work with his Montrals to create an effective sphere of awareness. If anything steps into that sphere, Keiji can attempt an attack with the knowledge that he won't over extend his reach. Although effective, the technique limits his movement speed to only slight shuffles and he refuses to strike outside his range, as it may upset his balance. Opponents outside of his Kill Sphere’s range have a decided advantage against this strategy.

Keiji knows how to take a hit. Growing up he was always getting punched, stabbed or shot at. He's learned to push past pain and dish it out. He wears armor for a reason and will often place himself in harms way to defend those he is loyal to. Everyone has a limit to how much pain they can take though, and Keiji pushes his to the extremes.
