A/N: This is probably different from the Izuku AUs since I am tired of the same thing.
You can say a lot about Izuku Mizuki. A bit of a quirky boy yet he is cheerful.
He does have a mother, father, twin sister and a few friends. Though he was blissfully unaware of his parents' occupation.
It was one afternoon during middle school when someone sat next to him. It was a blonde hair girl with dark red eyes. In her arms was a box full of odd objects.
Upon closer look, it was his stolen possessions. "Wait! Is that my things?"
"Yes." The girl spoke, "My brother is an asshole, right?" Izuku was taken back by the swearing but the girl continued her rant, "Thinking that he has a Quirk will make him a hero though he actually harmed people into submission. Please don't listen to his stupid advices."
"I was wondering..." Izuku spoke softly, "Could I be a hero?"
"Actually, you can become a hero, young Mizuki." A masculine voice spoke as a muscular blonde man wearing a blue bodysuit appeared.
Itsuki was caught off guard by the sudden appearance of All-Might. "Wait! How did you noticed us?"
"Wait, you said that I can be a-"
"Yes, Young Mizuki." All-Might spoke, "You can be a hero but there's people out there who had Quirks that doesn't use it for good but for evil."
"So, you're saying that there's people with Quirks that are villains?" Itsuki asked and All-Might nodded sadly, a small frown on his face which is odd because All-Might usually has a smile on his face.
Izuku did told All-Might, "I know that there's people who hurt anyone, there's others who can defend the innocent like you."
That speech brings back All-Might's trademark smile as the man pulled a piece of his hair out and gave it to Izuku. "Here. Eat this." Izuku was shocked as he was given the hair by his idol. Itsuki had pulled out a water bottle and gave to Izuku. "You need something to drink if you swallowed the hair." The green hair boy put the hair in his mouth and swallowed it, using the water bottle to flush it down. "Why are you here for?" Izuku asked the ashen blonde hair girl who walked to the railing. "HEY DUMBASS!!!" Itsuki called out to the ground, "I don't understand how someone like you wanted to be a hero when you bullied nearly everyone without a Quirk. HELL IF YOU WANT THAT DREAM OF BEING A HERO, YOU BETTER CHANGE THAT PERSONALITY BEFORE YOU BECOME A HERO!!"
It seems to cause something as Katsuki was getting mad as he ran off. Guess going to the roof as Itsuki looked at Izuku. "Quick! Hide your All-Might collection!" Izuku hid the box as Katsuki exit the door to the rooftop right as a masked man appeared out of nowhere right behind Katsuki.
"What the fuck are you-" Katsuki was interrupted when the masked man grabbed him by the ankle, catching the Quirk user off guard before dangling the boy off the railing. Now Katsuki was panicking as he saw how high it is. One wrong move and he's done for. "Confess your sins and you shall be spared."
Katsuki gulped before confessed everything which includes trying to suicide bait Izuku which sickens his own sister. "KATSUKI, WHAT THE HELL IS WRONG WITH YOU!!" Katsuki stared at his sister as he was safely place on the ground, "What!?!? He's Quirkless so that means he can't be a-"
"THAT'S THE REASON?" The masked man growled, grabbing Katsuki by the collar. "Perhaps your sister is right and the fact that you are trying to kill my son, you're pretty lucky that I didn't kill you." Once everything is done, the masked man jumped down and landed with ease. Itsuki looked down in as the girl looked at Izuku. "Can you get your stuff, Izu. We are following him." When Izuku heard that, he knew that if Itsuki found about the secret which leads to some awkward moments.
"Hey sir!" Itsuki called out to the masked man who saw Itsuki and Izuku who is carrying the box of his returned belongings. Izuku looked nervous for his friend and how she would react. "I would like to thank you for preventing a disaster but I don't get why Izu is sweating very hard." Indeed, Izuku is sweating hard until he blurted out, "D-Dad?"
When Itsuki heard that, she turned to the dark green hair boy and said, "The masked man is your dad?" Izuku nodded rapidly at Itsuki, "It's true that Izuku is my son." The masked man said before lifted his hands up to removed the mask.
Once the mask was off, Itsuki was caught off guard by what he look like. He almost resembled a mature version of his son (excluding the freckles) with dark hair and pink eyes. The uniform he is wearing is odd. It resembled a leotard but there is fishnet pattern at the collar and the sides. Itsuki was in shock that she almost collapsed but Izuku helped her. "Dad, what is going on?" He did recalled his father wearing that before. Hanzo approached his son who gave the unconscious girl to him.
"My lord." A voice called out as a man working in an office noticed them. "Yes?" The older man spoke. The older man look a normal man but his snow white hair, tanned skin and golden eyes tell a different story. "There's a school where almost the students had quirks." When the older man heard that, he was surprised.
Ever since he came here, there's something called Quirks. Looking at the footage, the man stood up as the person noticed, "L..Lord Darius, what are you planning?" Darius spoke calmly, "Setting an example to the Quirks, Doma."
"I am worried that my skills might be rusty." Shiranui said. "Hey, I know that you still got it since you are on par with Miss Igawa." Hanzo replied, hoping that it would encourage her. The reason why they are in this situation is the fact that their son had receive a box with a message telling to "Don't go to school."
"What does the message mean, Hanzo?" Shiranui asked her husband as the two traveled to the middle school Izuku used to go. Then there was a smell of smoke in the air that confused the couple. Is there a fire or someone cooking with a grill. Hopefully that person might be careful with the-
Shiranui and Hanzo stopped in their tracks and stared in shock and disbelief. A cloud of smoke billowed through the morning sky. Up ahead, a collection of students, staff, parents and some Quirk Heroes gathered the sidewalk and street.
Fire. The Aldera Middle School was on fire.
"What's going on?" Hanzo asked, hoping for an answer as the group aside from the heroes were caught off-guard. Endeavor and his wife, Glacia were there for keeping everyone away from the burning building. "I'm not sure, Hanzo" Endeavor answered as he stared at the middle school which is in flames. "Perhaps a villain with a fire quirk or some kind of electrical fire-"
Then someone came out of the burning wreckage, it was Yoshito Kuroi though he looks slightly horrible. His clothes are coated with ash and he's coughing a lot. Hanzo was able to open the gate as he helped the politician. Thankfully, an ambulance arrived right as Hanzo carried the man to the sidewalk with a stretcher ready for him. "WE GOT A SURIVOR!" One of the paramedics called out as they helped the man.
Endeavor was completely confused by this. "Hey Hanzo, how did he was in that building." The taller red haired man asked. "My theory is maybe that he is in the building before the fire." Hanzo said, "But it could be something more." Endeavor was curious by this theory but concerned for the safety of his family. He wanted to be a hero (despite his fire quirk might be a potential hazard) though he heard rumors about a Demon Gate. "Do you think a demon might cause this." The red haired man asked. "It's a possibility and I dreaded that it might be right."
