Allen's twin Alline?

The i makes an e sound not ehh but ee. I know by the pictures I've seen in 'mommy' and 'daddy's' room I have a sibling of the same age and with a similar curse. One day my best and only friend died and, while on her grave a big guy came and revived her. She cursed my right eye, I already had a (sorta) cursed right arm. I wanted to join the order so I began training under miss Socalo. I was trained in 3 years with a synchronization rate of 98%. I lost my cursed arm in the American branch and once I got it back, it was called Jokers Jewel. I understand my past and have never been to the Japan branch only the China branch. Now if only I could see this Allen that is my so called Twin?
A/N this is an idea I got in, seriously the middle of the night
