Description : Usami-chan has always wanted a pair of rabbit ears, and she finally managed to have a pair grafted. Will Mikura-kun think she's cute? But there's just one problem... she's suddenly become very 'sensitive'. For fans of Mimi Mix! - this is the same world, but it's not yuri. Four chapters total. It's the minimum possible ecchi, everything is off camera - maybe two milli-Toloverus.
