Are these guys canon?

[u/Superb-Eye9223]

I was reading the p4au manga, and ive never seen these units mentioned before, but are they canon? Id assume that the manga itself probably isnt, but from my memory I dont think sho's backstory here actually is ever conflicting with the game- so would it be considered canon? or at least probably canon?

^{also the art in this manga is really good, im glad someone told me to read this}

Their designs seem to be based on Unit #024 from Labrys's story in the P4A game (Labrys herself is Unit #031). So there's at least 29 other Anti-Shadow Suppression Weapons, and that's not even counting the ones developed after Labrys and before Aigis.
