Asataiyō (Njalm2)

The Asataiyō (朝太陽, Japanese for Morning Sun) is one of the seven Kyūtai forged by an unnamed Kidō master centuries ago. It used to be bonded to Amaya Kinaga, before it was later stolen by a bunch of thieves at the behest of a young nobleman two centuries ago, who sought to use its abilities for his own ends and meets.

Its currently bonded to, and jealously protected by Shigenaga Arma; the same man who ordered it stolen in the first place.

Powers
Growth: the Asataiyō's powers lie in the ability to influence and dominate the aspect of growth; whether it is organic or not - this allows its wielder to manipulate plant-life and limit or re-arrange the structure of spiritons and cells in order to physically change the appearance of the holder or anyone who the holder would desire to aid - it is capable of tremendous feats of power by direct extension; as a direct extension of these abilities it is capable of healing any creature in manners so complicated and expansive that even at this point the limits of its powers have never been found - its owner woefully believes it might be capable of truly god-like feats if used in the appropriate manner, or as she'd label it, inappropriate.

Immortality: The owner becomes immune to the ravages of time upon their body, making them un-aging from when they acquired the orb. This ability is shared among all the Kyūtai.

Shape Manipulation: The seven Kyūtai all share the ability to freely change their shape, whether it be a ring, belt or sheath covering.

Behind the Scenes
This is influenced greatly by the seven Ka'kari in the Night Angel Trilogy of novels.
