三月ウサギ

A beautiful white rabbit, mouthing off at others helps relieve his mounting stress levels. His dream is to become a human. To achieve this goal, Sangatsu has tirelessly researched and created many drugs, all of which he tests on himself. Having consumed so many drugs (all of which are failures), he's on the cusp of becoming an addict. He makes many suspicious "medicines" at the behest of King.
