Haru

Species: Netherland dwarf rabbit

Haru is the lone member of Cherryton School's gardening club. She is earnest and forthright which, in addition to her sexual promiscuity, has earned her a sleazy reputation. Haru is broadly confident, but a defeatist side sometimes peaks through her facade.
In spite of her caring nature she tends to keep people at an emotional distance.
