A tiger beastkin and the greatest of the Great Youkai, possessing the power to destroy the world. Long ago, she was tricked and sealed away by a monk, only to be released after a vast amount of time. "Nyahaha! I shall destroy this wretched world!" However, having been sealed for 2,000 years, her strength and hunger have reached their limits. It was then that she encountered a young man on the street. "Nya! You, give me food!" Because she was imprisoned for so long, Beom's current intelligence level is miserably low.

The young head of a family that has been searching for the released Beom for a long time. She originally intended to find Beom and exploit her. However, seeing how innocent and pure Beom is, she begins to have second thoughts.

A cat beastkin and a youkai who follows and adores Beom. She is characterized by her cute appearance and ending her sentences with "nyang." "Lady Beom is our savior, nyang!" In her human form, she doesn't use "nyang." However, when she gets excited or loses her cool, her tail pops out and her youkai speech pattern slips through. She loves catnip and sweet desserts.
