At a pet shop near the school's west gate, Vivian confronts Javier over his attempt to sell a low-tier undead pet called the Mutant Emperor Skeleton, doubting its value despite her awakened B-rank taming talent. Javier insists the pet's unique ability allows it to grow endlessly through killing, eventually becoming an Undead Overlord, but Vivian remains skeptical and accuses him of deception. To prove his claim, Javier calls a professional, Mr. Cobb, who arrives to inspect the pet. Meanwhile, Vivian hesitates to contract a highly promising slime with Tier-9 potential, signaling a tense standoff over the pet's true worth and next move.
