Eriol created Spinel Sun. He made him because Eriol knew when he needed Sakura's power to split the memories and power between him and the other incarnation of Clow Reed, Kero and Yue will get in the way. Well, Eriol made Suppi and Ruby Moon and well....um....er....He made them! Eriol is Clow Reed, in a way, but Sakura's father is the other half....
NakaruThis girl here, is actually Ruby Moon, but its not the real form, just like Yukito and Yue. Nakaru is a hyper girl who jumps on Touya every chance she gets! She calls Spinel Sun, Suppi because when she found out Keroberos had a nickname, she thought.....Ok maybe not, but I don't have to much to say.
