Kiran

Kiran is the Guardian Character of a young girl named Hinako Mizutani. She appears in episode 61. She wears a golden gown with diamond and star pattens, and has a golden tiara on her head. Her eyes and hair colors are both yellow. Kiran has a sparkling look and is a girl who always thinks positive. Whenever she sees someone troubled by something, she would go to help. Her personality represents the radiance that shines within her owner. Her egg drops on the road when her owner moves away. But thankfully, Amu and the others find it and take it into their care until she finally hatched. Together, the Guardian Characters go across the city while helping troubled people and finding her owner, Hinako.

It would seem that Kiran has similarities with Amu's Guardian Character, Dia, as they both represent the light that comes from within their owners. Source: shugochara.wikia.com
