(Name) is Ukai Keishin's younger sister, the coach of Karasuno's Boys' Volleyball Team. Just like her brother and the Karasuno boys, (name) eats, breathers and lives off the art of volleyball. After returning from Russia, where she spent some time studying aboard, (name) is asked to be the assistant coach for the Boys' Volleyball Team, which is how she meets Tsukishima Kei, the most irritating male on earth who never fails to make her life miserable. Everything about this guy makes (name) hate him, especially his mean and narcissistic personality, which ticks her off the most. At the same time, Tsukishima isn't a huge fan of (name) either. They hate each other so much that being in the same room together could set off WW3. (Name) is certain that never in a million years will she ever like Tsukishima, or so she thinks. What (name) did not expect, of course, was to fall in love with him of all people, especially with him being her first love. Read as (name) helps the boys' team soar to greater heights and meet new interesting people long the way while she figures out her feelings for Tsukishima Kei. Maybe, just maybe, he might feel the same way, too.
