A girl who attempts to cooperate with you. An A-rank adventurer aspiring for S-rank. An octopus demi-human girl with a curvaceous build and straight blue hair. Likely due to her octopus traits, she possesses immense strength and often puffs out her cheeks. Her weapon is a folding fan-sword. Her ability is "Shelter-pus," which creates a shelter for herself and one other person where they can sleep soundly for eight hours regardless of what happens. An absolute defense space.

The entity that will cause large-scale destruction and end the exam in seven days. A slime parasitizing the tower. It hides its core at the very top and covers the tower's exterior with mucus and tentacles. It merges its mana with the tower and the clouds hanging near the summit to create a massive magic circle in the sky. The moment the circle is complete, the tower instantly transforms into a nail that smashes the ground, crushing the crust while causing massive destruction above and below. It reaches the magma layer to use it as nourishment. It takes seven days for the nail to form.

A pair, a man and a woman, who occupy a large room midway up the tower as its guardians. A monster pair consisting of a faceless giant and a witch. The giant wears traveler's clothes and runs around the area at incredible speeds while carrying the witch on his back barefoot. Objects behind the giant have a gravitational property of being pulled toward him. The witch is a skilled magic user who supports the giant with spells.

An ambush specialist who wipes out intruders within the tower. A white monster with a flat body like the underside of a ray, featuring a giant vertically opening mouth and sharp tentacles. Parts of its body are melting, and it clings to the walls. It draws its own magic circles to manifest and can appear anywhere inside the tower. It vanishes once the prey is eliminated. It creates multiple tentacles from its melted body to slice and impale opponents.
