Some of the Trinity (british angelic school) students are explicitly called angels and archangels, at one point we see an ID listing a Gehenna (demonic german school) girl's race as demon and Trinity even sells off bombs loaded with holy water advertised to hurt them more.
Trinity and Gehenna are some of the oldest and biggest schools, being matched only by Millenium, which is an upstart that rose solely on technological achievement.
We don't have any loredrops on the rest of the girls and their specific races. We do know the species of the students as a whole are
Forgotten Gods.
In a later point in the story, one of the antagonists that treats the world as a TTRPG heavily implies their world is in a constant cycle of remodeling. The current one being academic-themed and the Forgotten Gods incarnating as its students this time (he talks about how
the Codex has been updated, the actual vicious destructive gods being a vestige from the previous world and mentions a Celestial Realm they have descended from). Some players compared the lore to something from Touhou due to that.
One of the girls from Trinity (clearly a fox but explicitly called an archangel too) notes that ancient scriptures say they were banished from paradise due to a breach of contract. Some players took that as just her retelling the bible, others that it might have been specific to their angelic species, which could mean all of the students are offshoots of Angels/Fallen Angels.
There was a lot of discussion about that early on, but the main writer defected to try to make his own game, it crash and burned mid-development and we haven't had much lore since then.
What we do know aside from that told in interviews:
>Sensei/the Player is just a normal human unlike the students who came from outside Kivotos so bullets are fatal to him
This is the main reason to believe they are a different species in spite of using
human interchangeable. There was a distinction. Some of the girls don't have any non-human feature aside the halo.
>Law and religion are somewhat laxer in Kivotos regarding combat and romance
This is the interesting part because while murder is still treated as 100% serious as it could, robbery, terrorism and the destruction involved is an everyday occurrence. Their society also doesn't seem to mind Sensei romancing multiple girls. Although there *are* possessive and needy girls they also don't seem to mind much him fooling around with other girls at least in their own club or school (they tease him about it, flaunt to each other receiving messages or try to wingwoman during events to setup a vacation). Outside those circles it isn't uncommon for a rivalry to escalate though (showing off or shooting girls from other schools).
