It's Cherry, the cook for their resteraunt! Luchs also helps Cherry with cooking. Cherry is sweet and daydreams alot. She's not as slutty as Bloodberry can be, even though she loves Otaru just as much! Another thing...
Hanagata learned this the hard way, comparing her cooking to Marine's and saying that it was like dogfood. You can guess what happened then! All and all, Cherry is a cute, smart and all around kind marionette!
