[A giant robot monster appeared in the abandoned town of Tokyo city.]
[Top 10 heroes went to deal with giant robot along with 50 more heroes. Reports are saying that it is the work of a villain.]
[It is said to be the manifestation of quirk.]
[Number 1 hero All Might along with Number 2 hero Bishamon fought together and defeated that thing.]
[Information is limited due to government intervention. It appeared to be related to one of the major villains.]
Media was discussing the biggest incident of the day where Japan's top heroes gathered to defeat a single enemy. It was also not a common enemy or ordinary villain. It was a gigantic 10 meters tall bluish mecha.
In one of the hospitals, a woman with blond hair was sitting with a blank face lacking an emotion.
"Calm down, Bisha. Rex will be fine." The man said gently holding the woman's hand. He had blue eyes and black hair.
"It's all my fault, Yato," Bisha said.
Sighed* Not far from them a big man with blond hair, sighed looking at the couple.
"How is his condition?" Asked a man in a police officer outfit.
"Chief? He still hasn't woken up. There appears to be no major injury though… that's what doctors said." All Might said. "Everything clear from outside?"
"Yes. The media is not bothering anymore as the Yaoyaorozo family took care of everything. That is the current condition. Shall any problem arise, I will inform Hero Bishamon. Please deliver this message to her, All Might." The police chief said.
All Might nodded and the chief went away. He then looked door of a room where a young boy about five years old sleeping.
Today was a tiring day for All Might.
First, he heard the news that Number 2 hero Bishamon's son was kidnapped. Then a giant robot appeared in an abandoned town where it started to wreak havoc. No residents were hurt but they found some dead bodies where that robot emerged but later they found out that those were bodies of some local villains.
But the problem didn't end since the robot was more than 12 meters tall and extremely durable. No matter how hard All Might tried, he can't just get through the head of the robot.
It was not like he didn't want to stop. It just that there was a possibility that the giant robot could be a manifestation of quirk. And he was right, the robot fired his gauntlet to an abandoned building and then stopped moving.
When heroes looked at where the robot shoot his hand, they found a boy about 5 years old. He was none other than Number 2 hero Bishamon and a great scientist Yato's son Rex Kinzoku.
Rex was now in the room still sleeping. But the one All Might most concerned about was Bishamon. This incident took a great toll on her. He hoped that she will be fine.
Soon the door opened and a nurse came out. "The patient is woken up. Please call the doctor!"
They all stood up and ran inside the room without minding the stunned nurse.
---
"What the…?" The boy woke his eyes and saw a sealing.
He slowly looked around his surrounding to detect a nurse.
"You are awake?!" A nurse stood then checked Rex's pulses. "I should call the doctor and your parents." The nurse said and ran out of the room.
The boy slowly rose and sat.
"Ouch... What the…" He felt a pinch and saw a drip was hanging connected to him. What shocked him the most was his metallic hands. Suddenly he felt pain in his head and a note appeared.
[Hi god here. As you can see, you have come to the new world. Don't need to worry about your body since it is originally yours. Just consider it like you have woken your memories. Well, things went a little down when I was talking to you. It's no big deal, you can handle it. You also don't have to worry about your appearance. It is just a side effect of your powers. You will retain your appearance when you become strong. There is another gift for you. It's called Rasen no Chikara or Spiral Powers. Consider that like Ki which will help you make machine and also the power source of you. Good luck with that.
PS: You are op once you figure your abilities. Also, harem will be legalized in the future.]
"The hell is wrong with him?" The boy silently muttered.
The door opened and several figures entered the room. One woman, in particular, shoot herself and hugged the boy when she found him looking at her with his lively eyes.
"Thank god you are alive… I will never leave you." Bishamon said hugging the boy.
"I think it's time you let Rex go…" Yato said. Bisha found Rex tapping her shoulders.
Bisha hurriedly let go of Rex who took a deep breath. "I am sorry. Are you hurt?"
"Huh… Do you want to kill me? And who are you clowns anyway?" Boy said. He couldn't believe that he was about to suffocate to death.
He found all people weird. First, there was this woman who has long blond hair and purple eyes. She was looking like a night. Yes, she hugging her son with her armor on. Rex thanked god, if not for his new strength, his skull would have cracked open just from the force the woman put.
Beside her was a man in a tracksuit who has blue eyes and black hair.
However, one boy found most bizarre was an oversize man wearing a tight outfit and looking like a western hero. 'He is either a cosplayer or a pervert.' Rex thought.
"Wait… you don't remember us?" Bisha asked. Rex shook his head slowly.
"That…" Yato also looked down.
Bisha shuddered but then took a deep breath to calm herself down. She then gently caressed her son's head. "It's okay, boy. Rest well here." Bisha said to Rex who nodded. She then looked at the doctor and asked, "Doctor please check him."
"I will see." The doctor started to check Rex for his impulse or any head injury. He also asked several questions to Rex who answered him. "Rex-kun, rest here. If you need anything then please ask." The doctor said to Rex.
"I want food. Something sweet will be fine like custard or chocolate cake." Rex said.
Hearing this, Yato and Bisha smiled. "You can eat anything you want," Bisha said to Rex then walked out of the room along with the doctor and others.
"Mr. and Miss Kinzoku, I am afraid but I think your son got a slight amnesia. Possibilities are that he will recover soon but if not it's best you take good care of him. He talked like a normal child which is rare since he was unresponsive when he awakened his quirk. I will get to a quick examination before I can say for sure. Now if you excuse me." The doctor walked away after informing them.
Bisha gritted her teeth then slammed her hand on the wall making a crater. "I knew that something was not right! Everything is my fault. If I was just a little…" Bisha said as tears started to flow from her eyes.
Yato shook her shoulder while All Might remained silent.
Bisha then wiped her tears and deforming her armor.
"Always be helping people while neglecting my own family. It explains how much of a failure I am. I have neglected my first child but I won't let that happen to Rex too." Bisha said then looked at Yato, her husband. "Yato, inform Hero Association that I will be retiring as a hero. Number 2 Knight Hero: Bishamon is no more."
