As a degenerate who actually liked Force, I am down for any Nanoha content, but I wonder what even is the point of telling an entirely original story using old character? Ah, who am I kidding, it's just brand recognition...
This really doesn't give me Nanoha vibes. Maybe it's just been too long; must of the newer ones don't really work for me ...
The original series came out 20 years ago. That's enough time for a writer to develop entirely new interests...
That feels like an alternate universe from the main series.
Feels very much like an alternate timeline to me.
