A Heroic Teacher In A Grimm World.

Grimm World

Ever since one Izuku Midoriya became the number one hero, his life was anything but heretic mayhem. Constant attention from paparazzi, over the top crazy fans, villains monologuing all the time, flying panties, etc, etc.

Suffice it to say, being kidnapped by a God and transported to another world infested by creatures called Grimm was the last thing he expected to happen.

... As much as his life story sings a different tune about crazy situations.

'Oh, Gods...' Izuku sighed while making his way through the most famous hunter guild in this world; Beacon.

Now, you'd probably questioning yourself how he know this bit of information about a world he'd never known that existed before he placed his foot on it, right?

Well, to understand, how - first you have to understand, why?

Simply, his status as a hero and as a potentially great teacher.

Yeah. His relevance to the said God criminal act is the fact that he is both a great hero and his capability of giving life-changing advice - hence, the teacher part.

And this world, Remnant, needs someone like this to inspire future generations.

So, the multiverse God, who was a thing for this particular reality, decided to kidnap the number one hero of another reality... To become a teacher. Just like that.

It was so ludicrous that Izuku froze for a few minutes until his brain kicked back to full power. Then, he started to question God. Because he can be as divine as he wants, it is Izuku job to protect his world from villains and his kidnapping would cause all kinds of shit to go wrong.

God, benevolent as he is, bitch slapped Izuku. A merciful smile on his face, and an aura of everlasting kindness around him as he pummeled his point on poor Izuku.

Then, he started explaining that while normally he couldn't alter the world of other deities, the one in charge of his original world is on friendly terms with him. So, he could and would give a push to the number two hero - Flash Freeze - to become stronger enough to beat any villain and take the position of number one hero.

While God - Kami was explaining it, he used the situation to tell Izuku that now, even if wanted to put him back in his original world - he couldn't. Said something about it being a law of some sort, but Izuku had another name for it...

Bullshit.

So, now, Izuku Midoriya, 26 years old and single, was walking to the headmaster's office while grumbling. Maybe he should be warier of his current predicament, but for some reason, he's not. Izuku was pretty sure it was kami's fault as he did say that for Izuku to enjoy his second life in this world, he would take some parts of his personality and add others.

Again, Bullshit.

'Wait a minute, did he put a bit of Katsuki personality on me?'

Izuku sighed. No matter what he says, he's actually grateful for being sent to another world.

Why the sudden change?

Cause in his original world he gained many things while on his way to the top.

... But he lost too many things to be worth a single title as the number one.

Saw too much dead. Too much evil. And almost became the very evil he loathes so much.

All in the name of revenge.

All for her...

Izuku shook his head. One of the deals he made with Kami - as he did let Izuku ask some things, because it was only fair after kidnapping him... As to forget some things... The things that haunt his dreams every night.

He's grateful for the small mercies. Not that he asked to forget everything. No, he remembers the important parts, but at least now he can sleep more than 2 hours a day without waking up.

Izuku sighed again as he opened the door to the headmaster's office. Two figures awaited for him.

'Well, let's begin this year! Plus Ultra Style!'

AN: Short Chapter. Some parts are confusing I know. Is just that I like to skip that whole 'talk to kami before being isekai-ed trope' and at the same time still wanted to give this Izuku a backstory.

As you can see, Izuku here will be a bit darker. No qualms about killing those who deserve it and considering this being a Grimm world, well... It works!

Lastly, this is not a crossover between Rwby and My Hero Academy. It was pretty clear that I said Beacon being a hunter guild.

Basically, imagine an isekai world where the Grimm is the main threat, but not the only one. There are more races than just humans and faunus.

Beacon is not the only hunter guild.

All guilds can ensure missions, like in an adventure guild. Students can take missions, but it normally depends on the year they are learning. Sophomore can't take high-level missions, only if they have teacher supervision.

This fanfic is a fantasy play with rwby elements and many others.

Rwby characters are the same as the original, a bit different in small parts, but original.

Rwby plot is in no way in this story. Like I said, original fantasy fanfic, but with rwby elements.
