Magic's Little Helper, Black Ocean: Mercy for Hire Mission 11

With Esper neglecting her duties as magical teacher, Tiffany takes her education into her own hands. Struggling with self-esteem and credibility with the universe, she resorts to trying a magical performance-enhancing drug.

Wouldn't it?
