The Age of Kaiju A brief period of history that lasted 20 years and ended nearly 50 years before quirks appeared. It was the darkest part in human history when monsters of a bygone era, stronger then most heros emerged with the first being Godzilla and others emerging soon after. It was dark times especially when humanity even unwittingly created several of them. In the end all Kaiju were killed off in by Godzilla who was on the verge of a nuclear meltdown. Which was averted due to it being managed by a truly united world as he took on an equally powerful Kaiju known as Destroyah. After that everything dealing with Kaiju was promptly eliminated and nothing remained of the era except for the legends. At least that was as far as Izuku knew it, until one washed ashore during training. One that could assume a human form. Now he has to help her out as he strives to be a hero. It won't be easy with dealing with school, villains, managing his love life, and making sure that she doesn't go on a rampage. Though in the end, he wouldn't change a thing about it.

One day a 4 year old Izuku Midoriya is taking a walk after finding out that he was quirkless. He was really sad that he couldn't be a hero like he always wanted to. This led to him being bullied and abused at school. One day on his walk home, the same bullies are bullying a girl with long periwinkle blue hair and same colored eyes. She seemed to be at least 1 older than everyone else. Izuku then steps in to stop her from being bullied but gets himself injured. When he tries to fight back, he awakens a power that he has never seen before. The girl who later he learns that her name is Nejire Hado becomes infatuated with the boy almost immediately after learning about what has gone on in his life. They start dating after a while but Nejire is going to UA , which forces them in a sort of long-distance relationship, but they are both loyal till the end. Nejire is hosting a succubus, and she eventually tells Izuku. Neither of them know what a succubus is until they learn that it's basically a sex demon. This is gonna be a long journey. (hosting a succubus isn't a quirk)
