When Ken Deabru escaped from the orphanage, he had trouble to eat full and one day he stole a purse from other people and since then he stole things to survive until now. Today he was in the crowded market; Ken looked at the purses of various people and thinking who the most suitable prey to target is.

And then he saw a woman about 20 years old is buying the vegetables but her purse was put on the vegetables stand while she was choosing the fresh vegetables.

Then the kid went to that Vegetables stand and hurry put the purse into his trousers pocket and left from this place. But what he didn't know is a hero and that woman already knew that he stole her purse.

After reached his hideout, between two old apartments, he took out his spoils and saw money at least 50000 yen. He grinned and prepared to leave when he heard a woman sound and a whip sound behind him and then he saw a woman who dresses like a pervert and holding a whip while grinning.

"Who are you?" said Ken. When the woman heard, she grinned back at him and said "My name is midnight. I am a hero. You stole my purse and asked who are you, you have got quite a lot of guts". When Ken heard, he thought for a while and said: "I have never stolen from the pervert like you". When that woman heard, her smile turned scary and pink smoke coming out of her body.

When Ken saw these pink smoke he knew that he mustn't smell or game over for him, so he jumped back for about 3 steps and transform to Bat Demon. Ken is a boy with black hair, red eyes and about 5 feet tall. After he transformed he became taller, from 5 feet to nearly 6 feet. He grew horns, tail, and wings from his back and the nails of his hands and feet became longer. When midnight saw his transformation, she knew that he might be a tough opponent. So she became serious and she attacked him first with her whip, her whip had the numb effect if the opponent was hit by her whip. When Ken saw a whip coming to him and was about to hit, he reached out his hand and caught the whip and pulled it hard. It happened so fast that midnight didn't have any time to think and when she realized, she had been pulled toward Ken. And when she was about to get near Ken, midnight released her pink smoke. When Ken saw this he knew that he had fallen into her trap, and he had already breathed too much midnight's pick smoke and he became sleepy.

When he woke up, he saw a ceiling he had never seen before and he saw a woman was with black hair, a sėxy body sleeping on the same bed with him.

Then he remembered that he had fainted after the fight with that hero. When he looked back to the woman beside him, isn't she the one whose purse had been stolen by him. When he looked at her face, hair, and body, he became sure that she was that pervert who fought with him and he realized he had stolen from a hero.

When he was busying with his thoughts he felt a movement beside him and saw that the hero was looking at him with smirk expression. And she slowly got up from the bed and said "So you woke up. I had called your orphanage and I heard that you escaped from there. Can you tell me why you escaped?" "When I was young I can't control my quirk skillfully and I can't transform back to human form so they bKenlied me because of that" answered Ken.

"I will introduce myself my name is Nemuri Kayama and my hero name is Midnight. What is your name?" said Midnight. "My name is Ken Deabru. 7 years old," said Ken.

"What do you want to do to me?" asked Ken. "If you want me to go to jail, I will fight for my freedom right now with all of my power," said Ken while looking at Midnight. After Midnight heard what Ken said she shook her head and said: "I would like to have a little brother like you how do you think?" When Ken heard what Midnight said he can't believe what he was hearing and thought was she going to use him in her weird fetish. But when he saw her sincere eyes, he knew that she was serious. "Then please take care of me," said Ken.

After staying with Midnight for 7 years, this year he had to choose academy for his high school. After talking over with it, she advised him to choose UA as she had a recommendation letter. Then Ken decided to went to UA as this academy is the biggest hero academy in the east of Japan.

Then Ken went to UA to take the entrance exam of UA Hero class. The exam is the running race that allows all tricks as long as you don't kill.

After reached his home, Ken cooked dinner for midnight and him. As he went to the underground training room to train. Midnight came back home and saw there is no one in the living room and she thought Ken might be training in the training room so she opened television and watching the comedy channel. After a while, Ken came out of his training room and saw midnight and asked: "When did you come back?". "A while ago" answered midnight. At midnight watching television, Ken prepared plates and food for dinner and called midnight to eat. During dinner, midnight asked Ken "How is the exam". "First place, I guess," said Ken. After talking with midnight for a while and washed Kitchen utensils, Ken went back to his room to sleep. The next morning, Ken saw midnight with an envelope in her hand sitting on the sofa while watching him came down from the stairs and said: "Here this is from UA". "Hmmm, I will open it now" he saw a metal coin with size bigger than normal coin dropped in the table and hologram opened as he saw a mouse standing with two feet started talking "My name is Nezu. I am the principal of UA, Ken Deabru you have been accepted to UA Hero class. You can come to school the next morning. Don't forget the school starting time is 7:00 AM and ends at 4:00 PM. Then please excuse me". After telling what he needs to say the hologram disappeared. Ken saw midnight looking at him with a happy expression. Midnight said "Congratulation for passing the entrance exam and welcome to UA

We should celebrate it with a hot pot. I will leave the cooking to you as I will go buy the drinks for both of us." "Ok" answered Ken and he went to the kitchen to prepare hot pot. After celebrating with midnight, Ken went to his training room while thinking "new school, new challenge". After training until evening, Ken came out of the training room and prepared dinner for midnight. After had dinner, Ken went to his room and prepared for tomorrow's school.
