Rumi Usagiyama (Mirko) was only 15 when she found a baby pup in an alleyway. Yep, the No.5 ranked Pro Hero Mirko, became a teen mother.
Mirko decided to take in the baby pup, otherwise known as Midnight. She moved out of her parents house and was in her own apartment, so she didn't have to worry about her parents finding out. Since she still had to go to her hero school, she would have to drop Midnight off at a daycare, to which she didn't like. All of the children would bully and make fun of her appearance. They would also tease her about Mirko being her mother, since their both different species.
Midnight decides to prove them wrong and strides to become a hero, her dream. She also wants to fight beside her mother, who would help her train 24/7. As she goes on her journey to become a hero, she runs into some love interests...
Will she achieve her dream and become a hero or will it flop? Will she find her mate before she becomes a hero??
