Miranda kind of regrets investigating the mysterious light in her closet, but she doesn't regret being the sort of person who investigates the mysterious light in her closet. Regardless, she made her choice, and now she's in an unfamiliar body in someone else's yard, with her semantic and procedural memory intact on a first glance and her episodic memory so scrambled she isn't sure who or where she needs to go home to. There's a hazy memory of recursively staring at herself through two pairs of eyes as the world melts around her. Hopefully this is the kind of isekai where there's still an instance of her back . . . wherever she was, and whoever she nebulously misses isn't experiencing her being dead.
Or possibly she's in the past and will catch up to everyone eventually, because her body is tiny. Is she five? Seven? She looks herself over as best she can without a reflective surface available and determines that she's in apparently excellent health except for being a child. She's definitely too young to get a job even apart from her lack of verifiable credentials or legal identity.
Probably she should look for a police station and try to get reintegrated into civilization. And not say anything that sounds too much like having total retrograde episodic amnesia or they'll stick her in a hospital.
This whole situation fucking sucks, honestly. Fuck.
