• Zanpakuto
  also known as a soul cutter. The source of a shinigami's power, it is currently in its weakest state. Yet, with Aaron, this is not a large problem. His Zanpakuto takes the shape of an ornately decorated Nodachi, or field sword, A greatsword that was used as a cavalry weapon most of the tim, with a length of over 80 centimeters. With his spiritual energy, Aaron is able to use this sword quite effectively nonetheless.

Abilities:

• Basic Kido:
  Aaron knows some of the basic Kido of the Gotei 13, and his studies are decent. While he has memorized many, however, he can only use a few at the moment, with his poor control.
  Air walk- As a shinigami, Aaron can literally walk on and use the air as if he were on the ground. It's definitely not flight, and it's only at the same speed he gets walking. However, this ability is automatic, making it impossible for him to fall unless he wishes to.

• Shikai: Balance of Light and Darkness
  As a result of Aaron being able to hear them now, He can use his zanpakuto's shikai, or "initial release" causing his zanpakuto to assume it's true form, as a pair of dual blades, one black and one white, which he uses to strike down his opponents. he has not unlocked all of their abilities, however, and as a result, can only get a boost of strength and speed from releasing them at the moment.
  

Biography:

Aaron was a "plus" or soul of the dead, that came across a shinigami in one of his missions. Before that shinigami could perform Konso, a hollow attacked both of them. The shinigami fought, but was injured when he did so, and saw only one chance - the temporary transfer of power to the plus nearby. Aaron gladly did so, and defeated the hollow after a long fight. soon after, he developed shinigami abilities of his own. He began to find evidence that something was not right amongst the thirteen court guard companies, however, and he began to investigate himself.
However, he was interrupted by Aeon and his need for him in the war. Aaron put his own problems aside for now and worked to bring order in the world, following Aeon. However ,he does question the war, and it's necessity, which is a matter he is keeping both eyes open in.
An archangel, taking some interest into him as he passed near the world, noted his power and his wish for order and peace. using a spell to teleport him away, he was brought into Aeon's armies. He accepted the request to join Aeon with the condition to be brought back to where he left off at the end of his service.

Alright, since you asked so nicely, I'll go more into detail. Editing
