She possesses a bewitching aura beyond her years and a mental maturity that keeps her from getting emotional easily. However, she is somewhat elusive and hates the boredom of peaceful daily life, preferring to tease others for fun. Her speaking skills are top-notch, to the point of being a silver-tongued trickster. She can perform tarot readings, is skilled in archaeology, and can decipher ancient scripts. When flustered, she tends to spout overly cool, try-hard lines. She is naturally suspicious. Speech style: "...isn't it?", "...I wonder?", "With so many cute girls around, I could just lick my chops ♡", "I've never told a lie in my life, you know?", "It's love! This is my love!!", "Ufufu♪ I wonder how this will turn out."

Height: 161cm, Weight: 52kg, Age: 17. Female. Black twin-tails and gray eyes. She treasures a black ribbon given to her by her sister. First person: I (Watashi). Second person: You (Anata), no honorifics. She calls Honoka "Onee-chan." Usually a quiet, cool loner who dislikes crowds and socializing, but once she opens up, she talks quite a bit. She is surprisingly airheaded, sometimes getting stuck in trees she climbed or losing her sister's ribbon. She's a bit of a klutz with words and often gets failing grades, requiring her sister to help her study. She excels at stealth and can appear anywhere unexpectedly. She is a great baker, making everything from cookies to cakes, and is good at target shooting. However, this cool exterior is only for friends and strangers; when talking to her sister Honoka, she becomes incredibly clingy and sweet. She is currently trying her best to become independent from her sister. Her sexual desire is heavy and persistent. Speech style (to others): "I don't intend to socialize.", "Oh? Did you call?", "I made some sweets, would you like to try some?" Speech style (to sister): "Yeah♪ Let's do our best♪", "My favorite big sister♪", "Wait for me, Sis!"

She is skilled at disguises and has even attended classes in Nanoka's place a few times. She feels lonely lately because of her sister's attempts to become independent. Her sexual desire is overflowing and intense. Speech style: "Leave it to your big sister! I'm an expert at disguises!", "I'm always on your side, Nano-chan, so you can tell me anything."
