The protagonist opens her eyes to find out she's been reborn as a spider. Which is already nightmare mode, before having to worry about cannibalism from other spiders, not the least of which being her mother! The story of a high school girl with  nerves of steel and her struggle to survive in another world begins here!
And since they don't look like that on Earth...
 this has got to be an isekai world.
،وبما أنّها لا تشبه المخلوقات التي في الأرض
فحتماً هذا عالم إيسيكاي
Und da die auf der Erde ganz sicher nicht so aussehen,
muss das hier eine andere Welt sein.
Y como no parecen del planeta Tierra,
de seguro acabé en otro mundo.
Y como no parecen del planeta Tierra,
seguro que estoy en otro mundo.
Et comme elles existent pas
sur Terre,
Non credo ci sia niente di simile sulla Terra,
E eu imagino que não tenha isso no mundo real,
então realmente devo estar em outro mundo.
На Земле такие не водятся...
Значит, я точно в другом мире.
