So I'm a Spider, So What? The Daily Lives of the Kumoko Sisters

Once an ordinary high school girl, the protagonist finds her life abruptly cut short, only to awaken reincarnated as a monstrous spider in a dangerous parallel world. Thrust into a sprawling, treacherous labyrinth teeming with hostile creatures, she must rely on her wits and newfound abilities simply to survive. The environment is unforgiving, forcing her to adapt quickly to her terrifying new form while constantly fending off deadly threats lurking around every corner. To gain an edge in this relentless struggle for survival, she activates a unique ability known as "Parallel Will," dividing her consciousness into four distinct minds to better manage the overwhelming challenges of the dungeon. However, what begins as a practical tactical decision soon spirals into an entirely unexpected phenomenon. Rather than remaining as fragmented thoughts within a single body, each of her four separated wills mysteriously manifests its own physical form. Now, instead of one lone spider navigating the perilous maze, there are four independent bodies sharing her origin, transforming her solitary fight for survival into the chaotic and unpredictable daily lives of the newly formed Kumoko sisters.
