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!
It's really looking like 
I reincarnated in another world!
!يبدو حقاً أنني خُلِقت من جديد في عالم آخر
Offenbar bin ich echt in einer
anderen Welt wiedergeboren wurden.
¡Parece que sí renací en otro mundo!
¡Parece que sí renací en otro mundo!
On se croirait vraiment
dans un jeu vidéo !
Ma quindi mi sono veramente
reincarnata in un altro mondo?
Agora sim ficou com cara de
reencarnação em outro mundo!
Становится похоже на настоящий исекай!
