I am the protagonist of this story — an ordinary high‑school senior, but suddenly I was reborn in a fantasy world and not just anyone, but as a spider monster. Trouble doesn't come alone. I awoke in a dungeon teeming with evil monsters. My only weapons are the knowledge from my past life and an endless stream of positive energy, and now I will have to defeat my opponents with webs if I want to survive. Thus begins the tale of how a low‑rank spider with incredible mental abilities survives in a labyrinth!
