Viper
Only Atsuko would see R.N.A.‘s tape and still be like ’yeah they won’t get off my case.' At least Viper wasn’t too deterred by her casually throwing out the idea of Viper burning to death; and considering it a mild inconvenience at that.
Viper “Nah, heard it’s way too painful, besides, wouldn’t wanna make you lift a pretty finger more than necessary.”
This would do just fine, wouldn’t it?

“…Good.” Being doted on, being not made to work… this was much more her style. If this island only had a shopping mall, she would be set.
Viper “I have adoring fans everywhere, dear Atsuko. I’m popular online, not the same, sure, but even here… Abel, Matsukaze, Asuka, I bet there’s more.”
Well, Atsuko wasn’t exactly popular anywhere, so she unfortunately didn’t care much for Viper’s self-proclaimed accolades. She was far more interested in watching the flame consume the paper, bit by bit, until it was nothing but ashes.

“You shouldn’t have burned the oar, then. You might need it to bat away all those adoring fans.” Was she being sarcastic? Probably. Maybe. It was hard to tell.
Viper “But I’m picky. I like a woman who knows what she wants, and who isn’t afraid to take control.”
Viper was really going for it and I, for one, am very proud of her. Atsuko… was slightly indifferent, but she was also happy enough to indulge the idea of just having someone she could order around. That could be interesting for sure.

“…Be careful with your words. Don’t you know I’m ‘evil?’ There’s no telling what I’d have you do…”
Probably just things like carry her belongings around and do chores for her, for the most part. Wasn’t that just basically being employed at the Hearth? But perhaps being wary of the inner workings of Atsuko’s love for the flame had special privileges…?
Viper “Dexter can try to control me, but he won’t get far. I doubt he will be able to convert me at all. However, I wouldn’t have trouble being under the control of an attractive woman.”
If everyone was this forthcoming and malleable to Atsuko, the entire world would have already burned down at her whims. Maybe she was going about things wrong the whole time? Instead of being cold and standoffish and waiting for papa to take care of things for her, maybe she could have used her beauty even more to get what she wanted? What a waste. Things could have been going so much better for her.
But it was never too late to start, was it?

“…If that’s the case, then entertain me. Bark like a dog.” ATSUKO.
