I suppose those two would be starring in something like "Children of the moon".
The color shemes for the hair /eyes or the clothes are not definite yet, but I like Getsuros green hair for now. I´ll probably keep it. Ichirus color is quite unusual but I think he could go with it.
Getsuro became a warrior to protect his little sister who is to marry one prince of the moon (Ichiru´s younger brother)but during this fight he was protected by Ichiru who never bothered fighting before. Getsuro suffered great damage to his pride. I imagine Ichiru saying something like "I only said I wouldn´t fight but I never mentioned I wouldn´t be able to." Well, I guess anyone would get angry. But, truth be told, Ichiru is really fond of Getsuro and doesn´t intend to hurt him. So him raising to arms means the situation was dire...
