Does anyone have any idea if "Kisaragi Sonami" is an alias? She writes tl smut under that name, and yuri is being posted on "namaniku" social media accounts, but looking at both types of comics (which btw are drawn in very different ways), I can't help but wonder if those two names don't belong to someone relatively new but already established, who wanted to draw r18 stuff, It's not unusual for artists to do things like that.
(I won't give out possible candidates I have in mind to not pollute anyone's thinking in "yeah, I can see that" kind of way).
