I do wonder why the title says it's going to be a love triangle when it's otherwise quite upfront about the endgame being poly

Because triangle vertex always connects with two others

it was unironically great.

Damn, i really like arata iri.
there's the same amount of explosive comedy, it's just there's more of mikotoxnekozaki gayness present
the only fault i can find is yozora's reworked design, but i'm more than willing to forgive for that glorious shot of half-naked nekozaki.

really nice shading, but proportions are kind of off. I'm betting that the heads are too big.
Also, if you applied enough pressure to pierce through armour your hand either would be in the gut because of impulse, or, if it was slow motion, awkwardly angled because given how high the tip of the sword red probably aimed from low point; she could have readjusted the grip but this would mean that at some point she just left sword in the blue lady, which is not very nice.
Pierced cape suggest swift motion, which means that she pulled out the hand out of her stomach, dragging sword with it. Yikes.

It's always a fun experience reading yuri and noticing that girls have long nails.
