Mimori Morino

She is a character that appeared in episode 73 who loves to examine cook recipes and to cook, but her talent in cooking is not perfected. Her Heart's Egg was made into a Mystery Egg by Lulu, becoming a character called Cooking Dream that makes anyone that eats her food say that it's delicious then faint. She can hear Guardian Characters' voices, like when she took advice from Su, thinking that she was a cooking fairy since Mimori could only hear her voice.
