Wow, I'm guessing this was early concept stuff for LWA? Or maybe the start for the OVA/Movie timeline.
A few notable things:
Sucy was a lot nicer in this manga than she ended up being in the anime lol.
Akko's family! The only time we see them and it's just barely lol.
They actually mention Japan instead of it being vague like in the anime
That mandragora thing is like the mandrakes from Harry Potter as most people probably realized. Though both ideas were probably taken from old myths.
Akko having weak magic was clearly not thought out yet. Thinking back she was also not as bad at magic in the movie timeline as she was in the show.
Anyway, really enjoyed this, always nice to revisit these characters (especially Akko! Love her) and the LWA world
