The characters of Kira☆Kira and their associated tropes.

- Attractive Bent-Gender / Even the Guys Want Him: As Shikako. His attractiveness is repeatedly lampshaded.
- Brilliant, but Lazy: Implied. He simply doesn't care about most things enough to try rather than actually lacking the ability. Several other characters such as his mother and sister appear to notice it as well.
