The main character, Cid Kagenou was not portrayed as a character who would emphasize emotions and relationships. But other young characters of the novel series are heavily impressed by Cid and his driven attitude. There are a lot of other female characters in the life of Cid Kagenou, most of them belonging to his alliance named the Shadow Garden.. Then at the very end, the final battle climax of everything, Shadow intervenes one last time while revealing himself as Cid Kagenou the useless little brother hidden in plain sight all along, says some more cryptic bullshit, and (fake) dies. The last paragraph is my own sort of speculation, but yeah that's an eminence in shadow.
Moreover, Aurora is capable of using atomic magic, Shadow's sure-kill skill. Of the many women that flock around Cid Kagenou, his sister Claire is someone he protects.. Cid Kagenou is the male protagonist of The Eminence in Shadow, a reincarnated modern Japanese boy who lives as a background mob noble while secretly acting as the legendary shadow ruler "Shadow," leader of the organization Shadow Garden, without realizing that his own chuunibyo setting has become real. In everyday life he plays the part of an unremarkable second son of the Kagenou baron.
