Not just a soldier, Riku is also a well-trained battlefield commander in his own right. Well versed in ground tactics, he puts his own experience into play when coordinating offensive and defensive manoeuvres. Unable to sit back and let his men do all the work he is usually the first one to enact his own plans. Rukia refuses to sit idly by as his men carry out his plans, preferring instead to lead from the front, much as he expects all of his men to do.

As an assault trooper, he is not beyond assigning the toughest parts of the missions to himself, not for the glory but for the chance to prove himself to those around him.

Riku wasn’t born, he was created. A soldier bred for one purpose and in some ways bred to simply know one thing; war. A descendent of the ARC Commando created for the Republic years ago and the Empires SCARs, his skills transcend that of a common soldier but it comes at a price. Bound until death to the Keibatsu family his entire purpose is to serve and die in their name.

Though granted the honour near equal standing amongst the family in recent times he still struggles with the concept of free speech, ideas and will. Loyalty binds him and in conflicts of interest between Clan and Family, he will always put his family first.

Unwilling to bow, except to the family, Riku believes the sacrifice of one is worth the saving of millions. This belief has no limits going as far as the ideology that full genocide of a planet would be better than the loss of a system. This dark outlook serves him well as a commander, enabling him to go that extra mile needed to secure the victory. He is, however, unwilling to simply sacrifice his own men and fellow Nihilgenia, causing some confusion amongst allies and potentially souring relationships with them as he is seen favouring his own.

Given he believes in the superiority of the Nihilgenia and Keibatsu over that of other beings this makes complete sense to the Commander. After all, if the best fall who would ensure victory was secured?

Having been grown for for the Keibatsu family, Riku has always wondered does he truly exist as a person. A clone of someone he will never meet, a child born without a father but with dozens of brothers who all claim to be him. The mental scars that have been left as he developed his own sense of self and personality have left trenches of self-doubt and worth. He often wonders if he is worthy of ever holding the Keibatsu name on top of wondering wherever he is worthy of holding the simple title of human.

Unwilling to give up he pushes forward every day. However, as he emerges from the background into the forefront of a Clan he feels the crushing presence of self-doubt begin to emerge once more and old scars begin to open and bleed.

As a Clone, Riku was trained from inception to not value his own life, to follow orders even if it meant his own demise. He was a part of a brotherhood, a minor part of a greater whole, and sacrifices were often necessary.

Unafraid of death almost to the point where he seems to enjoy the adrenaline rush that comes from the near misses, Riku pushes past his own limitations, throwing himself into harm's way. This daredevil attitude has been personified in his aerial combat, utilising jetpacks and high explosives even in the midst of heated combat.

Personal flight. The endorphins and adrenaline released from having a jetpack strapped to his back during combat. Trained to fight from the air Riku has all but mastered the use of the personal propulsion system. Utilising rockets, grenades, his trusty Westar M-5 and brilliant positioning he adapts to his surroundings to gain the upper hand. He sets up the battlefield to his advantage and turning it into a death trap for anyone bound to the ground. This expertise also aids him in drop assaults from transports.

Rukia's manipulation of the chaos of battle to his advantage takes time, and while he is well studied in modifying plans due to changing circumstances, sometimes abandoning the plan is inevitable. This causes Rukia some discomfort, causing him to angrily resort to other tactics.
