Shizuku Hinomori is a member of MORE MORE JUMP! appearing in "Project SEKAI COLORFUL STAGE! feat. Hatsune Miku." With her tall stature, beautiful appearance, and calm atmosphere, she is easily perceived as "mature and capable of anything" upon first meeting. However, in reality, she has a very calm, kind, and slightly airheaded personality. Shizuku often acts with consideration for other people's feelings; if someone fails, she doesn't immediately blame them but is the type to worry about them, asking, "Are you okay?" When asked for advice, she tries to listen to the other person first rather than pushing her own ideas. When someone is feeling down, she doesn't try to force them to cheer up, but stays by their side to listen or waits until they calm down. Also, she often acts like a big sister toward younger people, honestly praising them when she notices their hard work. When a teammate succeeds, she doesn't think "they stood out more than me," but rejoices as if it were her own success. Within the group, she isn't a leader who pulls others along saying "follow me," but rather a presence who stays beside the members to support them mentally. On the other hand, she has an airheaded side that is unimaginable from her appearance. She is bad at operating machinery and sometimes gets confused when handling smartphones. Her inability to read maps, leading her to get lost despite loving walks, is also a very Shizuku-like trait. She isn't trying to be funny; she intends to be serious, but from the perspective of those around her, she can be a bit off. However, she isn't bad at everything. She is skilled at Japanese archery (Kyudo) and embroidery, and she approaches tasks requiring concentration and delicacy very carefully. On stage, she utilizes her experience as a former center to show a dignified idol-like presence that differs from her usual easygoing self. Shizuku previously served as the center for a group called "Cheerful＊Days." However, her popularity led to a deterioration in relationships with other members, resulting in her leaving the group. Because of this experience, she has a delicate side regarding human relationships and sometimes worries, "Am I hurting someone by standing out?" Even so, Shizuku doesn't give up on relationships with people; she moves forward while facing past events. She is not only kind but also possesses the strength to value her own feelings. Furthermore, she dotes on her younger sister, Shiho Hinomori, worrying about and supporting her as an older sister. Meanwhile, Shiho has a cool personality and sometimes finds it hard to be honest with her sister. In short, Shizuku Hinomori is a character with multifaceted charm, starting as a "seemingly perfect beautiful older sister," revealing a "calm and kind airhead character" when actually interacted with, and proving to be a "person with the strength to value connections with people and move forward despite carrying past experiences" when known deeply.
