Hikari's power manifests itself as the Hoshi Rikka Shi-rudo, which literally means ' Star Excellence Shield ', to the unknown eye it is just a normal bracelet with 6 charms, but within each charm resides a fairy-like creature. Each fairy are seperate manifestations of Hikari's spirit. Each fairy has their own unique name and appearance. Though Hikari initially needed to chant an incantation to use her techniques, further training has rendered this unnecessary. Her incantation consists of voicing the names of the members involved, followed by the technique name and the phrase "I reject", a reference to the nature of her powers. Since Hikari's power is fueled by her emotions rather than spiritual energy, the only limit that has been shown to it is her own confidence; any self-doubt weakens her abilities and can cause them to fail. However, it would likely to be assumed that if she fuel her power with high confidence and determination to cause severe damage, or to defend in extreme, her abilities are at the greatest height.

Santen Kesshun (三天結盾, literally "triple heavenly linking shield") is Hikari's defensive technique. The incantation arranges Susei, Kasei and Dosei into a triangle, forming a barrier capable of repelling most things, but has limitations.
Koten Zanshun (孤天斬盾, literally "solitary heavenly cutting shield") is Hikari's offensive technique. The incantation summons Mokusei, who forms a thin barrier on either side of himself that cuts through enemies like a sword. However, when Mokusei is destroyed, Hikari is unable to use this technique until Mokusei is revived. Koten Zanshun is the least effective of Hikari's abilities, not because of any lack of power, but because her own pacifist nature. Since the technique is invariably lethal if effective, Hikari is conflicted about whether she truly wants it to work, and thus any powerful foe can block the attack.
Sōten Kisshun (双天帰盾, literally "twin heavenly returning shield") is Hikari's healing technique, though it goes well beyond simple healing. The incantation summons Kinsei and Tenousei to form a half-oval barrier around whatever or whomever Hikari wishes. While active, the barrier rejects all negative events inflicted upon anything within the barrier.
