Through strict discipline and daily regiments, a body naturally acquires a level of Reiryoku in order to sustain their spiritual presence and potency. There are few with a well of Spiritual Energy of such a depth as Akimoto, and even fewer who've surpassed it. As a result, he tends to infuse his body with Reiryoku for the smallest of tasks so he can maintain a level of energy without it spilling out against his will.
When not in a state of release, Akimoto can train for 12 hours with occasional 5-minute breaks. However, his released forms require much energy. Still, he's capable of employing two Meiji simultaneous for thirty minutes. Past this point, the releases immediately disengage without his will.
Releases that prey on the mental capacities of their opponent have a rather difficult time affecting Akimoto. He has the ability to meditate for up to eight hours without growing restless (though this is largely due to his naturally active personality and tendencies). There are few things he's never been able to see through, and none that have ever been witnessed.
Legendary Reiatsu
Rusted copper and brilliant sunsets are the manifestations of Akimoto's Reiryoku. It's just as warm as it looks but tends to have the taste of metal and the ash of a campfire. It feels light, however, but is rather opaque.
At its lightest, it can feel calming. This is when petals of a pale orange seem to bloom and fly from his body as if taken by the wind. At its heaviest, it can burn to ash all in its vicinity almost immediately, though this requires almost all of his Reiryoku to sustain for a duration of about 10 seconds. This is when he is engulfed in an impossible bonfire of a deep orange and rust.
Akimoto is known to exert a constant stream of Reiryoku that, due to its naturally calming nature, is notable. It's so insignificant to the amount of Reiryoku he stores that it doesn't deplete his Reiryoku to any evident degree. In fact, he's able to sustain this level of Reiryoku without consequence. It's also not uncommon for him to use his Reitsu's abilities to: start fires, when needed; to play a little jest (though this is a very rare occurrence); or to deescalate situations where appropriate.
Legendary Resilience
All his training has translated into lifestyle choices that reinforce an almost exclusively vegan diet, meditation to focus and still the mind. This creates a fortitude of body and mind that is almost impossible to taint or influence.
Any hand-to-hand martial artist can employ any weapon as if the extension of one's own hand. However, with so much focus on his own body and his form as well as the utter lack of physically employable Meiji, Akimoto has utterly forgotten any skill associated with armed combat. With so much skill and utility of his physical being, there is no real reason to arm himself with anything other than his own body.
No Talent in Kenjutsu
Any weapon is employed like a blunt instrument and without any kind of finesse or tact. Any kind of parry against him will likely disarm him of whatever weapon he, for any reason, would be using a weapon.
Angles and leverage are lost to him. A weapon is a foreign concept that is handled with the awkwardness of a child. Though his grip can withstand great force, it would be unlikely that he'd be able to block any kind of attack with a weapon of any kind.
No Resonance
Without a Zanpakuto, there is nothing with which to resonate. Though he once had a very high resonance with his Zanpakuto, that Resonance was lost when he unlocked his abilities for Shinkaku. Any resonance he once held was turned into a focus on his Alignment and Hakuda abilities.
One such as he needs no explanation as to his talent for anything Hakuda. He spent almost all of his time within the Gotei sustaining the branch of Hakuda he developed long before entering the Gotei. Kori no Tate is his go-to for any combat situation and he would be hard-pressed to fall out of this technique.
Taijutsu Legend
Despite his despise for anything offensive, his centuries of perfecting his defensive skills has translated to his astounding level of understanding any offensive techniques. He understands that sometimes an offensive technique must be applied in the place of traditional defense. Regardless, there is little strategy or tact.
There is virtually no attack or strike against which he cannot defend. After millenia of study, practice, and training, his ability to react to strikes, whether obvious or slighted, is nearly perfect. Though he is intimately knowledgeable about deflecting and redirection, he will usually block or meet the attack with some kind of counter. He's often referred to as an "immovable object" that has yet to see an "unstoppable force."
Legendary Strength
Dedicating oneself to everything defense might make one assume physical strength is not a priority. Akimoto makes this assumption a fallacy. He must be impossibly strong to withstand blunt attacks without deflecting or redirecting them. This has translated quite well into his ability to disintegrate a foe when need be.
His time in the Shinigami Academy was spent continuing to improve his Hakuda while also acquiring skills in Zanpakuto, however slowly. He would have been expelled from the academy if he didn't learn at least the simplest of Kido spells, which he did so reluctantly. After barely graduating the Academy, he forsook any further practice of the art. Regardless, he respects Kido immensely and holds an appropriate level of reverence toward it.
No Stability
Regardless of the fact he has notable skill in Kido, any spell he would cast wouldn't be able to hold the power of his Reiryoku without outside assistance.
Transcending Alignment
The discipline of a Martial Artist is renown in any culture and on any plane. Akimoto is one of the highest examples of this. His existence has been that of training to protect, protecting those he respects, and fighting those who wish to take from him or those he respects. He holds himself to a very high level, higher than most ever even consider. His training regiment is ludicrous to all and insane to some, to the point to being considered utterly excessive and obsessive.
This passion to pursue the perfection of one's physical and mental body has helped him to understand everything about himself. He understands what he lacks and why. He understands what he's best in and what he can improve over time. He understands what he doesn't understand and he is constantly seeking knowledge of what he has the most knowledge about. He has revived Hakuda from a state of complacency and comatose, to one of the most underappreciated and powerful skills one can attain.
If not for the his own training, he wouldn't be as skillful in Hohō as much as he is. Most of his skill in Shunpō comes from the strength in his legs and body. If he exerted any more Reiryoku to further power his Shunpō, it would be far too easy to track his movements as a trail would be left behind that could both be easily seen and felt. Because of this, his own technique of Karada no Kabe is often employed, which is largely the reason for his reputation as an "immovable object."
Legendary Mobility
Someone with so much power is likely to lack flexibility, adaptability, and overall agility. Akimoto has surpassed these perceived bodily limitations as well.
Legendary Perception
With such an intimate level of one's own body and physical ability and capability, Akimoto can quickly gauge others' movements, direction, and intent. He can skillfully spar with any individual (up to ten) while blindfolded and come out victorious. His keen senses enables him to miss almost nothing.
