Kochō

was one of Kikyō's assistants; she was one of two shikigami in the form of a young girls. She and Asuka are mainly used as Kikyō's messengers after Kikyō was grievously wounded on Mount Hakurei by Naraku.

They are also attendants for Kikyō's other shikigami, Saint Hijiri, who is just a puppet and container for Kikyō's soul. Kochō and Asuka are also capable of erecting and maintaining powerful barriers.

The girls are slain by Kohaku when Kikyō sends them to divert Naraku's attention and stop the invading demonic rats. However, Kikyō later summons them again to protect Kohaku (who has become her traveling companion since Kagura's death).

Personality
Not much is known about their personality although they are extremely loyal to Kikyō and are obediently following her orders even putting themselves in danger as seen when their barrier that was protecting Kohaku was broken by Byakuya and used their last amount of spiritual powers to let Kohaku escape and to buy him more time but they were destroyed by Byakuya, telling them their effort was futile.

Physical description
Kochō has a ponytail at the back of her head, like Kikyō, wears a light yellow kimono.

Powers & Abilities
It appears that Kochō and Asuka both contain a vast amount of spiritual power as they lend it from Kikyō's powers, due to the fact that when Kikyō is distracted somewhere else (usually in difficult circumstances), they cover for her in her absence, though their powers seems to be connected to Kikyō's own powers, which leaves them almost powerless when Kikyō was defiled by Naraku's spiderwebs. Their spiritual powers manifests as a bright yellowish aura.
 * Flight: Both Kochō and Asuka are shown to have the ability to fly swiftly, so much so that they can keep up on a running horse.
 * Spiritual Barrier: Being Kikyō's shikigami, the two can defend themselves by erecting a powerful spiritual barrier which prevents any attacks from harming them. In various occasions, they are seen erecting a barrier to protect Kikyō during her recovery and while she was incapacitated. They are also seen erecting a barrier to protect Kohaku from Naraku when Kikyō was caught in Naraku's spiderwebs.
