so she decided to come back to Lily or is this the "other" Marika?
She came back, obviously. Even had a letter from the other Marika to the little sister.
The fact that she physically teleported to the other world annoys me. I definitely had the impression that she was mind-swapping, otherwise how did this Marika wake up suddenly in the Yuri world? Did Marika-B take an extra dose with her and just send her there to take her place? If so...Man, isn't that pretty villianous? Merits at least a confrontation, I'd think. She could've just claimed to be a lost twin or something, but nope, let's randomly force my other self to go to another world while she's sleeping haha.
Oh, but she wrote a letter to the sister that loves her who she's abandoning forever, so that's nice I guess.
Marika-B is trash.
