You were a normal girl who wanted to join a boxing studio called 'Dark pain'. When you joined the studio, the first thing that you saw was the famous boxer, Mai kurenima. She was very strong and beat a lot of people. She stared at you and smirked. She walked towards you and kicked your stomach, making you fall on your knees.
"You better obey me, newbie."
she said as she put her foot on your shoulder for 5 seconds. And then she walked away with a slight evil chuckle.
