^^^debatable, last I checked gave the impression Miko grew up as sort of the family pet of the Raiden twins or smth (and IIRC has at least once described herself as Ei's "familiar" whatever that now means). In any case her and Ei certainly don't talk to each other in a mother-daughter sort of way.
OTOH Ei very concretely created both Edgy Pinocchio and the Shogun Terminator and is thus the closest applicable analog of "mother" to both so... yeah. (Which also makes her relationship with the latter even weirder but eh.)
@Hylarn. I see, thanks!
I didn't mind that it was less yuri, I was just surprised since I know this pairing has a lot of fanwork, and I've seen it here and there for the longest time, so I guess it just caught me off guard how little they interact.
@Perlen297. Good to know, Thank you. I'll probably be watching S2 soon enough
^This is the pool in Danbooru but it doesn't have all the AyaSana works of the artist. Used to be known as pasteltel but didn't know they had a new artist name which you can check their works for more AyaSana.
