Hikari is a black kitty, who lives with her younger sister, Naokomi. Hikari is calm and civil, and sometimes, shes really aggressive. Hikari is sometimes mean to her younger sister, but she'll love her sister, no matter at what cost. If anyone hurts her younger sister, she would give them a first warning. But how about the second warning? She will scratch their skin. And the third warning? She'll end their life. Even thought shes aggressive-looking, she's calm and civil.
