Puny and powerless after an unfortunate encounter with a magical girl, the Dark Realm's Number Two has her work cut out for her in the world of humans!

When the magical girl responsible for the fall of the Dark Realm appears before her, the Great Jahy seizes on the opportunity to attack--and gets a taste of true terror.
 
With the enemy close at hand, it's time for Jahy to double down on her domination of the human world. Can she collect more mana crystals? Could she maybe even restore her dignity?!
 
Even when the workouts are hellish, even when the neighbor in the apartment next door won't stop making noise, the Great Jahy will not be defeated!!
