This is Rena Ryugu (that's the official translated name, but it should be Rena Ryuugu). She is in the same grade as Keiichi. She has strong obsession over anything that looks cute or anything that's "cute" in her definition. Because of this, she goes into what is called "kawai mode"(cute mode) that she's so focused on achieving what she wants. Her strengths are strong determination and thinking logic is what she is capable of in a tough situation.
