Meet Kazahaya and Rikuo. By day, they are two ordinary pharmacists at the Green Drug pharmacy; by night, their boss has them filling 'special prescriptions' for clients with ailments that can't be cured using ordinary elixirs. With cameos from the cast of Suki, this CLAMP series is a perfect dose of mystery, psychic powers, and those ornately drawn characters for which the femme-four creators are so justly famous.
