Black Iron Magician

[Passiflora C]

I've searched through the archives, and it appears it hasn't been suggested before, so here it is now.
A work authored by Mayoi Doufu of Black Summoner renown, who has actually interlinked both titles together, as will be even more evident with the release of volume 21, and illustrated by Nyum.
Complete at 7 volumes as per 2021.

(On the web novel side of things, it seems there's yet one more work in the making, once more connected to Black Summoner. )
All swell for action time.
