Kuu is a Sun Peacock which is a support-type Box Weapon that clothes its feathers in dazzling glowing Sun Flames. Incidentally, there are times when the Peacock's cry is heard as a shrilling "iya~n". It was first seen when used to heal a group of Varia soldiers.
It is possible to provide medical treatment to injured individuals though the Sun Activation Flames exposed from its feathers. Because the area-of-exposure of its Flames is much greater than that of other Sun Box Weapons, it demonstrates a splendid conspicuous service when there are many casualties.
- Healing Panel: Kuu's healing technique, despite its great efficiency the Activation of the Sun Flames also cause a rapid growth of nails and body hair. It seems that such drawback can be avoided by lowering the power output and, consequentially, the healing speed.
