An unlockable character from Mahjong Soul.
She has long blue hair tied into a half updo with a ponytail. Her eyes are red.
Haruna is a girl with endless power, who never gets tired throughout the whole day. She is an optimist type, who can screw around with boys. Haruna can't resist to have an ice pop and once made a great speech about her goal "to try all the flavors of ice pop in the world" in her composition class. In her spare time, she always brings cat food to the street cats nearby and plays with them. Although Haruna calls herself "Leader of Cats", the street cats seem to regard her as a small attendant who often brings food for them.
