For Kira, his and a friend's role play characters from Kingdom Hearts. I cannot remember all of the information, but.. I will try. Please tell me if it is incorrect.

The left is called Yuki, he is the heartless form of human Yuki. His eyes are red, they are yellow when he is in his 'dark' form. I have also made a mistake, when the eyes are yellow the heart on his shirt is upside-down.

The right is Kiyux, he is the nobody form of human Yuki. He has many scarves to cover the scars on his neck from suicide attempt. He also has freckles.

Kira will most probably tell more, I cannot remember their story.
