Though he does not remember any of this (yet), Caine was guardian to Sailor MuCephei. His family had been protecting hers for centuries and when he was assigned the task of mentoring the young daughter, he took it seriously. Their relationship wasn't always on friendly terms. The daughter considered him to be old fashioned, boring and strict. He didn't understand her obsession with 'dark' things such as the occult and tried to steer her away from that direction. Though she wouldn't understand it, he had worried about her obsession with things he considered darker in nature and he was only seeking to protect her.
To say he simply loved her would be an understatement. He was in love with her. She could frustrate him like no other but even during those moments, he wanted to reach out and hold her. Shelter her, protect her from the dark elements of the universe. He knew their relationship could never be.. right? It was unheard of for a guardian cat and a senshi to become more than adviser/pupil, so he tried to keep his feelings to himself whenever possible. What would their friends and family think if they knew what he thought? What he felt?
He considered it a blessing to be at her side. To be able to watch her grow into the amazing Senshi he knew she would become.
When their previous life was at an end, he vowed the he would find her in the next life, once they were reincarnated and he would once again protect her and see that she went towards the right path. During his years waiting for her to seek maturity, he spent his time studying the occult. It kept the loneliness away as it reminded him of her and gave him a better understanding of it as well. It was only a matter of time before his clothes became darker and accented with skulls and chains, slowly adapting himself to her interests. Nothing would make him happier than to bring a smile to her face and perhaps this time, he could be less old-fashioned. This was a new world after all. A new beginning. One that perhaps would end on a brighter note.
Of course, that was before the Negaverse got a hold of him. It was nearing the time for Sailor MuCephei's awakening. He looked forward to spending his time once more with Ume, instead of being the cat that followed her to school and back. He wasn't content enough with her petting him and yearned to be able to speak with her once more. To be more than just.. a cat.
The Negaverse was strong. General-King Charonite was a worthy adversary and as stubborn as Caine was, he could not resist the darkness for long. His memory is damaged, his heart is shadowed and he seeks nothing more than to follow his lord's wishes. But deep down there's an emptiness, a reminder that something greater, something really important to him.. is missing.
