The original story? Where's the original story?!
Hey! I couldn't find a link to the original story. . but if you're interested in stories with similar themes like 'Azure and Claude' that are also written by THE SAME AUTHOR, here's a link! https://www.novelupdates.com/nauthor/sugaru-miaki-fafoo/
I'm not sure if there is an English translated version of "Azure and Claude", nor do I know if it was even based off of a light novel written by Fafoo/ Maiki Sugaru.
