Unnbjorg Signar ユンビョルク・シグナル

Unnbjorg, nicknamed Yuna for short, is one of Lotte and Asuha's friends. She has short green hair and a tall, slim figure. Unnbjorg has been seen to be one of Lotte's level-headed friends, although she can go as to nearly berserk whenever someone acknowledges her flat chest. She has been the first one to believe the misunderstanding that drinking directly from a dairy fairy's chest after a bath will make the chest size grow bigger.
