Dairi's Eternity Larva seems a lot like Goshiki Agiri. She's very laid-back and takes nothing seriously, her eyes are always closed, and her dialog text is also thinner than the others', making it seem like she speaks softly. She also breathily lengthens the last words of her sentences the way Agiri does.
Yeah! Her name is Abraham Lincoln!Ah~
It's Cirno-chaaan.I think you're quite a bit more than a little off.I gots it! She's Eternal Ramba Ral.Ohhh~! How you doing!?Ahahaaa~Cirno-chan, are you friends with her?I think you're a little off~I'm off! Thinking, thinking! It's Engagement Ring, right!?Was it Ekireishiki Reikyaku Kikou (Liquid-Cooled Refrigeration Mechanism)!?Can't you see that's still wrong!?If you're having that much trouble, I guess Ramba Ral is fiiine.NO IT ISN'T!!In the end, they settled on "Larva".
