A/n: Back with a weird original idea... Sorry if it's bad!

Title:

I'm sorry Hero! But I'm not a princess!

--------------------

Story:

Once upon a time, there was a Hero who is summoned from another world to our world to defeat the Demon King!

And because the King cannot send the Hero back, the King gave his daughter to the Hero and the Hero marry him as a reward for saving the world

The End...

Well this is the legend and fairy tale that has been told to children around the world

And in this new Era, another Demon King appeared and no one knows how could another Demon King appear? It's only been one year since the newest Demon King is slain by the Hero...

But we'll in this world for some reason Demon King always appears 10 years after the last one is slain

But well now a war started

And the King of the largest kingdom called Gaiste

He decided to ask the Priest and the Court Mage to combine their power to summon a strong Hero

Usually, only need either just the Priest or just the Court Mage to do this

But it seems this Demon King is stronger than the previous one as it defeated the other Heroes who are summoned to this world by the other Kingdoms and have defeated the Demon King before

And so A Hero was summoned

The King promised the Hero that he will let the Hero marry the princess as a reward

And so the Hero was able to Kill the Demon King in a Week... Week... A WEEK!?

The King was surprised by this and troubled...

Why is he troubled?

Well, that's because he has no daughter!

Which means there is no Princess!

And The King didn't have time to go adopt a child to become a princess so she can marry the Hero

After all, a Week was unexpected... As most Heroes need at least two months and some need a Year to kill the Demon King

And so the King ordered his Sons or the Prince to be Princesses, and even order them to wear some dress, and then let the Hero choose who the Hero wants to marry

Of course, they rejected that order

The First Prince went to the Hero and try to charm the Hero with his Handsome face and charming Voice, he plans to try charm The Hero without the need to look like a Girl

But the Hero has irritated and disgusted feelings which can be seen from the aura surrounding the Hero as the Hero's face was covered and hidden with something the Hero called a Helmet.

Then come the Second Prince he is a muscle head, and so he challenges the Hero to a duel and loses, but he was carefree about it and just laugh at his loss and joke about it

This gets a Thumbs up from the Hero for respect.

Then come the Third Prince and he decided to look like a Princess and all

And he tries to charm the Hero and Manipulate the Hero so that he can gain the power to become the next King instead of his brothers

But it seems like the Hero knows what he's planning and punched him in the gut so hard he puked and collapse.

Then comes the fourth Prince who also looks a cool onee-Sama like looks

This makes the Hero interested until the Prince says that he's only wearing and looking like a girl like this because his Wife wants to see him in it, and he also screams saying he only loves his wife...

Well he's not married yet but he is engaged, and he loves his Fiance

This time the Hero punches the King in the Gut for making someone who is clearly in love with someone else being a candidate.

And now there the Fifth Prin-... Why are there so many princes!? And yet no Princess!?

Well this is the last one, if the King does not decide to try to go for another one in the hope to get a girl

Well, either way here we have the Fifth prince! Our Protagonist

He also come in looking like a girl and was super fidgety and vibrating from nervousness

After a few talks, The Hero is Happy and decides to have him

And so they married happily after ever

The end~

" What whyyyyyyyyy!? " the fifth prince says

As he heard that the Hero liked him

Well, he doesn't want to get married to someone he just meets and there is also the fact that he is the Fifth prince which means there's no chance of him being a King, so money is going to be hard...

Well, The Hero frankly doesn't want to get married either but the King insisted on marriage rather than giving the Hero money or status because it was a Tradition for every Hero that the reward has to be married to the Princess...

And so well the Prince say " B-but Hero I am not a Princess! "

" Well what a coincidence I am also not a Hero, I'm just someone with a Title called Hero," said the Hero

" B-but i-im not handsome so why me? " asked the Prince

" Well, so far you are the only one who doesn't have any weird intentions and also you're cute! "

" I-i see... But I don't think just cause I'm cute is enough to be chosen... H-how about the third elder brother isn't he also cute? " said the prince

" Nah he's a thot! Wait... Not exactly a that what was the male version of Thot again? I forgot, but so far you are the most decent one and the cutest one! And don't underestimate Cuteness! Cute is justice! " the Hero said and scream like it was a fact

" I... I still don't think you go with me, h-how about second older brother or first broth-! "

The hero shush the prince by closing his mouth with her hand and let go after a few second

" Alright one more words of he is better and I'm not, then I'm going to make you never say those words again " says the Hero

" O-okay... "

And so with that, they got married...

Well even though they're Married they kind of still start off as friends with both starting to know each other.

And so with that start an adventure of the Fifth prince who has nothing and the super OP Hero, romcom adventure!

And also the Hero is like any other Isekai don't have any Common sense about this world common sense! And so it's up to Mc to teach her that or at least tried...

--------------------------------

A/n: As for the looks

The Mc will somewhat look like this

When he Not crossdressing and when he crossdresses

-------

And then for the Hero, she would look somewhat like this
