Minato Yukina is a third-year student at Haneoka Girls' High School and is the cold and fierce leader of Roselia. She is a powerful vocalist, sparking the admiration of the other Roselia members. She is next-door neighbors with Lisa, who is also her childhood friend, and also considers Ran somewhat of a rival. 

Yukina has a cold-blooded and cut-throat attitude towards reaching her goals, cutting down any obstacles in her path. She expects nothing less than perfect and takes practice very seriously. Because of this, she has no qualms with chiding or insulting someone if she feels they are underperforming. She is openly dismissive to people she deems below her standards.

However, with the few people who are on her good side, she is not quite as strict as usual. She also has a liking for cats, though she refuses to admit it.[1][2] While she is indifferent to most things that aren't singing, Yukina also sees this as her weakness.

Outside of her bandmates, whom she calls by their first names, she refers to everyone with their last names.
