Fukinoshita-san wa Sega Chiisai

Fukinoshita, a well-behaved, palm-sized flower dwarf, is the most popular girl in her school. On the other hand, her childhood friend, Onigashima, who is half oni and half human, is a delinquent and outcast. A lively interspecies romantic comedy around two people who have feelings for each other yet cannot be honest about it!
