Luisa is a puppet featured in the film Whisper of the Heart.
She is mentioned by Shiro Nishi. She was whittled alongside Baron Humbert von Gikkingen, because they made a couple. Shiro brought the couple in Germany, but he didn't take Luisa, because she is on repairing. He wanted to take her later on, but the world war broke out. He couldn't find the store, where he brought the Baron. So Luisa is seperated from the Baron forever.
