The way I understand this is that once Ruruna turns someone into a kin, even she can't undo it. That kind of creeps me out a little. It's like Rununa is destroying the person and making them into something else.
Judging by the non serialized version, the person’s personality stays in tact (Wakana’s friend is still loyal only to her friend, she’s rebellious against Ruruna) she just can’t cause Ruruna harm due to orders
It’s not like who they are as a person is changing or anything, it’s more likely that Wakana like being ordered around
Yeah I guess you're right. The girls "under her control" never did seemed really under her control lol. Still the whole can't be undone thing feels a little icky. I followed the original girl × vampire despite my reservations. Might as well buckle in and take this ride too.
tbh, it felt like none of them were really under her control. i'm not even convinced that she can compel them to do anything less than not beat her to death. wakana in particular seems to have been desperate for the kind of connection that ruruna offered, her friend is iffy but there only because she's worried about wakana, and i feel like she could just leave if she really wanted to. ruruna wants her to like her though so she'd be annoying about it. the teach is a freak, i dunno what to say about her
