Oliver Horn, the main character in Reign of the Seven Spellblades light novel, anime, and manga, also has the nickname "Noll". So maybe it's a thing in Japan?
Anyway, such an amazing series. I gushed about the entirety of this series in the manga's main page, so I won't say it here. Just about this last volume.
There's so much potential for stretching the story with Naru-Mai-Eugene love triangle and Mai's struggle to decides which one she actually loves as the last arc. But alas. It is touched very lightly here, at least. What a bittersweet first love for Mai. Actually, thinking about it, this last volume is pretty anti-climatic, with most reveal about Naru coming from Monk-san's galaxy brain move. But everything wraps up nicely except for Eugene's killer, so I can't complain much.
