Do you have the link to the full manga?

Im aware of most of the characters in Super Thracia (which is the hack Claus is from) like Gerik, Sothe, Oliver, etc. but while playing, there was this particular character in which I was curious about, and I'm convinced he's from somewhere else, because he's certainly not from the FE Series here is his portrait If anyone has any leads to where he's from, let me know, because I'm genuinely curious. Btw, I'm not good at creating threads about finding a person, so excuse that.
