Poron emerges later in the series as a young witch supporting character. Her uncontrolled magical abilities often cause irreversible mishaps, like shrinking herself to mouse size without restoring her original form. Mischievous, selfish, and prone to unintentional chaos, she remains endearing within the group dynamic. She integrates into the core trio with Sally and Cub, energizing their interactions. Her magical blunders frequently involve Cub and the Hanamura triplets, sparking unpredictable events—such as stealing the Great Magical King’s horned staff to instigate Earth-bound mischief.

The sequel expands her background: identified as Sally’s adoptive sister, strong implications suggest she may be an abandoned human child adopted into the magical world. This origin foreshadows a potential future where she must permanently return to the human world. Emotional volatility defines her; uncontrollable crying or distress destabilizes her magic, triggering chaotic side effects. A notable subplot involves her precocious crush on Yamada-sensei, a married human teacher expecting a child, complicating her human-world experiences. Across the series, she subtly evolves from a comedic troublemaker into a more integrated group member, occasionally joining Sally and Cub in quests and magical challenges.
