Kumo desu ga, Nani ka?

Synopsis

As Nameless's parallel minds eat way at her mother’s mind, they find that they have been locked in as she suddenly makes her way out of the labyrinth to pursue Nameless herself. Finding herself completely outmatched, Nameless teleports back to her nest in the labyrinth but is ambushed by more Taratects. She tries to flee but is stopped by a Puppet Taratect - a small spider monster that operates a human-sized mannequin. Driven into a corner, she finally turns the tide by killing one and leveling up, which fully heals her, before teleporting herself and the remaining ones to the lava floor, where they die from the heat. Afterward, having reached her level-cap, Nameless evolves yet again. In the present, Ms. Oka informs Shun and the others that Hugo is planning to attack the Elf Village, so they decide to head there to stop him, except for Leston who opts to stay behind to deal with the kingdom's current situation. However, this journey will take them through the very same labyrinth that once housed Nameless.
