Nobara Sumiyoshi is a tomboy who loves volleyball and is the successor of an old-fashioned Japanese restaurant - a job that her mother wishes upon her so much that she forces the girls' volleyball team to disband before Nobara can join. Frustrated by her mother's decisions, Nobara leaves home to seek help from her aunt, who lets her live in the boys' volleyball team dorm with one condition: Nobara must act as the dorm mother. Determined to play volleyball at any cost, Nobara recruits five girls and forms a new team. However, her mother still stands in her way, so with the help of her sister Nobara convinces her mother to allow her to play only until she graduates. With only three years to pursue her dream, Nobara must find a way to lead her team to victory and juggle new friendships, romance, and her duties as dorm mother.

Thus begins the crazy relationships of Haruna, Yoh and their friends as they all struggle to find themselves and their true loves.
I'll admit that the plots of these manga are not too similar, but I can't help but compare these manga. The main reason they remind me of each other is the similarity of the heroine in each manga. The main females are both tomboys, athletic, and inexperienced at dating. High School Debut is mostly about dating, while Crimson Hero focuses on sports. While reading these two, I can't help but feel like they're almost a view of the same character as if they were in a different situation.
