In a World Without Light, I Found You

I was transported to another world with a single, vague mission: save it.
The catch? There were no instructions, no welcome guide, and definitely no cheat system to hold my hand. Armed with nothing but my wits and a bizarrely perfect control over my own body, I have to figure everything out from scratch.
Just when I thought I’d finally found a guide in the form of a cute girl I’d just rescued…
She looked me in the eyes, her expression firm. “saki anadawa wadaxini dasikedekulemasida aligadogosaiimasi.”
“…Sorry, what?”
She seemed to be protesting now, her face turning red. “demo hentaikoewa damedesi, sikunakudomo kalada o hadaganixinaiyide！”
“Huh???”
I can’t understand a single word she’s saying! You’re telling me I got isekai’d without even a basic language translation function?!
In a world filled with strange creatures and hidden dangers, my journey begins with the most fundamental challenge of all: just trying to ask for directions.
(This is a non-clichéd isekai adventure featuring a smart, overpowered protagonist, dual female leads, and no system.)
