Айдзава Чідзуру

Chizuru is the proud owner and manager of the Lemon Beach House. She is Eiko Aizawa and Takeru Aizawa's eldest sister.

Unlike her sister, Chizuru is much calmer and cares more for Ika. She tends to be more quiet and reserved, and she's almost always shown with shut eyes and a smile no matter the situation. However, if something occurs which she does not agree with, she has a darker violent side of herself: Being shown to have a terrifying, menacing aura coupled with a very dark mindset towards anyone unfortunate enough to make her mad. Whenever she is angry, she 'opens' her eyes, usually to freak out or intimidate the person (or squid) she is angry at.
