[@Fenris123] I'll take part of this as I haven't specified it clearly in the OP but Sho wasn't active until the BR itself in which he rejoined and was put in charge of a flank. His faction came into being about two months after parts of W-1 and the E.U. officially managed to give him control of a significant portion of the remaining black knights that were in southern Japan. How they managed to do this was a mix between Hirai's spy divsion allowing them to find the splinter factions in need of a leader, and the E.U.'s reinforcements via W-1 itself and some older Japanese soldiers who abandoned Japan shortly after the original war. As such unless you were directly placed under Sho during the time of the Black Rebellion you'd have been under a splinter faction of generic black knights for a month or so before being picked up by Sho's forces.

However I do take an issue with how long he's been with the Black Knights. According to the Cs it says he served as a spy when the Black Knights showed themselves to the world at the time. I'm not sure how'd that work as you are technically an honorary Britannian from another conquered nation, Ireland to be specific, which would lead to some major trust issues there more over you participated in the Shinjuku incident and were sparred by the rebels at the time meaning they know you participated in a full on assault on innocent civilians. 

I would recommend rewriting it and trying to think of a new bio. I'm am not trying to bully you, or push you around. It's just as it stands it seems you're trying to keep your old story together but it is flawed in a way which makes very awkward at best trying to implement it into a story full of Ex-Black Knights, Japanese Liberation Force Soldiers, and European Black Ops.
