Coffee Buns is an 18+ Transformation Visual Novel set after the events of Mice Tea. It's been two years since since the worldwide release of Kemono Tea, which turns the people who drink it into anthropomorphic animals. Society is still adjusting to the idea of real-life furries, but that doesn't mean you can skip your day-job.

Leonardo Bianco is a barista at a struggling café. His boss feels like hopping on the furry train might be just the thing to attract customers to the floundering business. Via a connection at another local business (which some returning readers might recognize), Leo and his co-workers are offered a chance to try transforming themselves. The tea works as advertised, but for Leo, there's more changes he didn't anticipate.
