Honestly the only person I've ever seen underrate Airi's pipes is Airi herself Sasuga no confidence
I love the dragon siblings, the rest of Nijicanceled, and I liked Zaion, and Nina
Selen's non stop trolling and laughter is infectious
Elira's singing and gremlin tendencies are great
Enna's ennaness is the only way I can describe how fun Enna is also her singing
Fulgur is just a really funny guy with good dark humor
Same for Vox in Collabs tho I don't tend to touch him with a 10 ft pole solo
Nina's family dynamics the rest of EN never got old (I miss you fox mom)
And Zaion just has my favorite kind of humor which is why I still follow her as Sayu
Also honorable mention to Pomu and Mika they're pretty good too
