女未 あかね

Your genius little sister and the second-oldest of the Onami girls. Akane wants to come across as both a cute girl and a proper lady in front of her family. She always wants to show her beloved brother her best side, but her powerful aversion to the cold turns her into a bit of a goofball whenever she desperately tries to evade its icy grasp. When the hugging rules were put into effect, she started warming up by keeping her arms locked with Onii-chan's in bed. [From JAST Store]
