It's a tough call.
Go north. Follow the River.
Go east. Follow the coastline.
Chase after the Oasis Gang. Get her stuff back. Maybe get re-captured. Apparently the slave collar around her neck 'counts' when it comes to her bizarre inability to free herself from bondage. She tries to ask her slimesuit to do it for her, but her throat locks up, her mind locks up. She can't ask. And her slimesuit isn't proactive enough to do it on its own.
It doesn't help that a part of her likes it. She doesn't naturally get off on following orders but it feels a bit like a missing piece of what her natural kinks are, like the collar is completing her somehow. It's a shivery thought. But she does want it off, she can feel the reluctance in herself to interact with society again while its still on her, not fear, but awkwardness.
Chasing down the Oasis Gang and demanding her stuff back with the collar still around her neck would be awkward. It'd be awkward even without the collar, actually, but the collar makes it an order of magnitude worse. It's not like she's attached to any of that stuff.
So, the alternative.
Write off the stuff she got dropped into this world with, leave it to the Oasis Gang as a further thank-you for getting to live out one of her fantasies, and go in a different direction. Normally she wouldn't get within ten miles of a jungle, but on this world... the calculation is very different. Not only is Mira herself basically invincible, the jungle itself is... not like a jungle on Earth would be. She can tell, even, just by looking, isekai-implanted knowledge bubbling up inside her brain: she knows what all of the plants around her are called and what properties they have, and she knows how to use what she finds to keep even a frail baseline human alive in this literal tentacle-hentai jungle, nevermind her superpowered hentai-girl-dream-body.
Mira always loved the jungle aesthetic, even if on Earth she kind of hated being in nature in full generality. In this new realm, though? It literally is a tentacle-hentai jungle, not a 'real' jungle. Sure, if she didn't have magical superpowers now she still wouldn't go near it, but it's not revolting like a 'real' jungle, like nature-on-Earth, would be.
And she remembers the broad strokes of the map she arrived with. To the north? Less tentacle hentai. To the east? More tentacle hentai.
Well, when Mira puts it like that, it's kind of obvious which direction she's going, isn't it.
