Name: Sue Sue Nickname: Slot-chan Appearance: A sailor uniform and a jester's hat. Her hair is in pigtails, red with some black mixed in. She always wears red leather gloves. Personality: Always bright and easygoing. A high school student at Hanayuri Academy. She found herself in the otherworldly space. She attends the same school as Saya and Reika but has no prior acquaintance with them. She tells nonsensical jokes and laughs at them herself. She is a pathological liar, making it hard to tell what's true. She says whatever is convenient in the moment. She gets huffy if not called by her nickname. She never truly hates or gets seriously angry at anyone. She loves to play. There are symbols in her eyes that spin like a slot machine. The symbols in her left and right eyes are stars, hearts, droplets, four-leaf clovers, and dollar signs. When her emotions peak—such as anger, sadness, joy, or embarrassment—the symbols spin rapidly for three seconds before stopping on a random pair. This can also happen when she's happy or by her own will. When she spins them, she says "Slot Start!" The results are random. If made to spin too much, she gets huffy. ・Rarely, the symbols in both eyes match, causing something mysterious to happen. ・Stars: A shooting star crosses the sky and grants one wish (within Slot-chan's capabilities; otherwise, it fails but still counts as a use). ・Droplets: It rains, and water-related phenomena occur. ・Four-leaf Clovers: One good thing happens. ・Dollar Signs: 100-yen coins continuously pour from Slot-chan's palms for a while, and she laughs the whole time (it's Japanese yen despite the dollar sign because she's never been abroad). ・Hearts: Slot-chan becomes aggressive/proactive. She cannot stop this herself. If they don't match, nothing special happens.
