I will now call our mc Ryūu
=====
Ryūu's first years of his new life passed in absolute peace. He was learning to walk and talk all over again. More or less having figuring out his surroundings,Ryūu occasionally begged his mother to aimlessly browse on her laptop to learn even more about the universe he was trapped in.
Rei didn't deny her little genius that supposedly at his four years old, he had already learned to read a syllables!.
"My Hero Academy anime! Good, good, good! I only watched three seasons without reading the manga. But I think that's enough to get used to the wonderful world with quirks, too!"Ryūu pondered, sitting on the couch and cuddling his little sister, Shoto, who was sleeping to the sound of the TV, which looked just adorable.
The right side of her hair was snow-white, resembling the world's most delightful ice. The left side, on the other hand, was dyed a fiery red, which usually always made their beloved mother nervous.
"I don't even know if I was lucky or not. I was born into Endeavour's family that holds the proud title of second hero after All Might. I rarely saw him in all four years, so it's hard for me to say anything about his character. In the anime itself, however, he is portrayed as the most common family tyrant. Hmm... However, I think it's still too early to put a verdict on him, because I'm probably in some alternate reality where things could be very different. After all, the original cold Shoto was born here as a pretty girl,"Ryūu continued to think hard about the situation.
Ryūu himself had acquired a beautiful appearance in his new life, with unusual short bluish hair and beautiful sea-colored eyes. The image of a sixteen-year-old unremarkable Japanese schoolboy slowly receded into the background.
He thrust his small right hand forward and turned to the unknown current in his body. At the same moment, a blue flame appeared in his palm that covered his entire hand in an instant.
A fire with such a striking appearance was obviously very, very unusual, for the temperature in the room,the room did not change at all after the fire was litup. In fact, if one examines the flame in more detail, it is clear that it was neither hot nor cold. "Amazing element of the Mythical Phoenix!"Ryūu exclaimed to himself. Unfortunately for him, he had never been able to test the same lauded regeneration from the legendary bird.
Usually at age four, all children officially register their quirks at the city's main medical center. A quirk is a special ability that often transcends all reasonableness. Eighty percent of the people on the planet earth possess it. Teleportation, flight, purple balls on their heads.
All this is quite possible in this strange world.
Having a strong and rare power, you can, in fact, achieve a lot in this life by getting the same profession of a hero.
Born into the family of Enji and Rei Todoroki, Ryūu was given the very famous world quirk of generating fire itself and controlling it.
He was wildly pleased with this acquisition, as gaining such an ability would make it even easier for him to completely subdue the devil fruit of the Phoenix model. Shoto, on the other hand, received a great combination of her parents' quirks, just as in canon. Honestly.
Ryūu didn't even know what he should do in such a situation, for Endeavour is bound to take up her cruel training at some point. It was quite possible that a childish girl's psyche simply could not stand such a thing. "I won't let that happen! Never!"with a determined gleam in his watery eyes, he exclaimed in his thoughts, instantly putting out all the blue fire.
In four years, Ryūu managed to become so attached to his little sister and sincerely love her as a member of his family.
"Ryūu , Shoto, your father will be here soon. Get yourself cleaned up and go meet him," Rei Todoroki said with a strangely anxious smile as she entered in the living room with the children.
She walked over to the couch and took the remote control, turning off the TV.
Ryūu patted his little sister lightly on the shoulder, waking the little angel. Shoto looked around sleepily, wiping her multicolored eyes tiredly. Hearing something about her father, the girl jumped off the couch and ran into the bathroom to wash off her sleepiness with tap water.
"Mom, why would Dad suddenly unexpectedly like to see us? Besides, when are Shoto and I going to see our two big brothers and our big sister?" Ryūu asked with innocent curiosity, playing the part of a typical four-year-old child.
Rei Todoroki said nothing in response, patting his blue hair lovingly.
Ryūu noticed her strange behavior, but didn't worry much about it. He didn't know yet that from this day on a real hell would begin, during which all his passive and good-natured character would undergo tremendous changes.
....
An hour later, there was a loud knock on the door of their house, Ryūu and Shoto's mother went to open it, letting in a tall, muscular man with short red hair and turquoise eyes.
Rei stepped aside, and Endeavour walked into the main room, seeing his children grown up since the last time.
Enji Todoroki measured them with a stern and heavy gaze. Shoto wanted to greet her father with a joyful childlike cry.
However, when she saw his tall figure at a more or less conscious age, she lost all her joy, becoming nervous to look at her brother. Ryūu, on the other hand, froze in shock, under the oppression of the Endeavour's infernal flames.
The man's fiery beard was blazing in the main hall, making everyone else present sweat excitedly.
"Shoto, I assure you that you possess the most powerful gift of all. Controlling fire and ice, it is on your shoulders to surpass the Almight!"Anji Todoroki said in a solemn and low voice, smiling at the corners of his lips.
Endevour was eerily happy that his daughter had awakened such an amazing fancy. The man had always dreamed of being hero number one. But he realized that his potential just wasn't enough. It was for this reason that Anji took a girl with white hair and an icy quirk as his wife. Giving Rei the role of a kind of incubator, he began to create children so that they could become the strongest heroes in the future.
Nevertheless, in his mind Shoto was the most special of all the other children of the Todoroki family. For a long time Endevour chased after just such a child. At the boy with blue hair, however, the man no longer looked at him.
Ryūu had no choice but to remain silent on the sidelines, for he had not aroused much interest in him. Shoto, on the other hand, did not quite understand her father's words.
Being a silly little girl, she took her big brother by the hand and ran up to Endeavour's leg, clutching tightly at his pant leg. "Everything goes according to canon.
I think the best thing would be to reveal my devil fruit of the Phoenix model to my father, so as to become stronger and help my little sister. I'm afraid his obsession will get out of hand. In that case, it would be best for me to keep Shoto in my shadow.
When you look at it that way, my goal in this world is pretty simple: to become the strongest hero and collect a huge harem!"Ryūu thought to himself, turning his determined gaze to Enji.
The man, on the other hand, looked into the serious sea-colored eyes and made an important decision for himself to check on his third son. Nothing would happen if he also took him with him for a while.
"We'll go to my agency, where you can both practice your quirks. So hurry up and don't waste my time,"Endeavour said in a cold and stale voice. He nodded to Rei and called her to talk to him alone in the kitchen.
Soon Ryūu and Shoto were alone in the room. The girl continued to shift happily from foot to foot, not letting go of her big brother's hand. However, Ryūu did not share her joy, anticipating difficult times. For four years he had had time to relax, living in silence and affection. In addition, closing his eyes, Ryūu mentally turned to the system, seeing that the icon with the tasks shimmered with iridescent light.
