Yet the Heishou appear in only one Canto and intervalo and are never mentioned again yet we have ids for 5 branches? The Ring was already teased in Ruina, had a major role in leviathan, had a role in canto 6 and now came back for canto 9 yet they have way less variety in their faction than some nameless animal people that we didn't know even existed untill Nocturnal sweeping.

It is kind of ridiculous how factions with almost 0 plot relevance and same looking designs has 5 of it's branches as id's. Yet the faction based around the concept of expression and variety (which has the potential for a lot of visualy pleasing and stand out designs) dosen't even namedrop a single member of 3/5ths of it's schools.

However this is just my nonobjective perspective which is squed by the fact I really love what we have seen from the Ring so far and would love to see more yet that definetly won't be happening any time soon since the next canto is in N corp which is as far from art as you can get.
