Since the angel-themed story I submitted a long time ago was finally approved (late news, sorry), I ended up actually expanding the story of the Angel Knights mentioned in that story into a series. Yes, I know I'm putting more pressure on myself by adding another series to write. But I don't want to lose the idea just yet. Well, from the submitted story, Aithen and Neriah had made an appearance and both were introduced as Maxiel's friends. But there were other Angel Knights, as well, who were close to Maxiel and were very dedicated to their duty as the Angel Knights on Earth.
