Description
Kikka Sengoku is a second-year student at Saotome University, where she is enrolled in the Faculty of Sports Science. Her background is that of a naturally positive and ultra-optimistic young woman who enjoys an ideal and fulfilling college life. Her birthday is on June 10th, and she stands 159cm tall. She is described as having brown eyes and orange hair that reaches her shoulders.

At her core, Kikka has a personality defined by a simple and carefree philosophy: she does what she finds fun and avoids what she finds boring. This outlook on life is reflected in her constant, relaxed smile and her generally cheerful demeanor, which is often described as being able to brighten the mood of those around her simply through her presence. Her interests are centered on social and enjoyable activities, including beauty routines, visiting cafes, spending time with her friends, and fortune-telling, with a particular fondness for the Four Pillars Divination method.

Kikka's role in the story is directly tied to her involvement in the university a cappella scene. She did not have a deep or pre-existing passion for music beyond it being a source of fun and entertainment. She discovered a cappella almost by chance, seeking an enjoyable pastime, but quickly and unexpectedly became a standout and highly regarded figure within the university's a cappella community. Within her group, she serves as the lead vocalist and also provides the second chorus.

Her key relationships are characterized by the positive energy she brings to her social circle. She is loved by her friends and is often surrounded by them, valuing these close friendships as an essential part of her happy life. Her talent and unique charm have earned her high praise from another character named Mizuki Fujishiro, who states that Kikka possesses not only excellent technical skill but also an irreplaceable and rare kind of star quality or charisma.

Kikka's development as a character is shown through her unplanned rise to prominence. Despite having no grand ambitions in music, her natural disposition and distinctive abilities have propelled her into the spotlight. Her notable ability lies in her singing voice, which is said to possess a magical quality; it always sounds as if she is smiling, a trait that has the power to lift the spirits of listeners and naturally make them smile in return.
