Magical Girl Magical Amber

The (fake) amber magician. A mysterious hooded girl. Her slogan is “Chemical! Magical! Medical!”
She appears as the guardian of the safe in Kagetsu Tohya, and also shows up while playing as Kohaku in Melty Blood. Ah, could there be some sort of connection between the two…!?
…In truth, she's a broom girl, not a magical girl, but that's neither here nor there.
Day after day, she throws herself into the manufacture of strange and suspicious drugs. She is a staff officer in the Tohno Mansion Basement Kingdom.
…Somehow, she seems like an even better fit for the Tatari than Sion, but the less said about that the better.
