Sure. I'll make you a hero... if you become my wife/husband (MxF, FxF or FxFuta).

Hello again! Would you like for one of your characters to become a hero, or heroine? Well, do I have an idea for you then~

The exact plot details are something I would like to plot out with you, but a rough framework I wanna give is: Your character has always dreamed about a career as a hero. Help people, get riches, become famous, and eventually retire with loads of gold and connections. The only issue: The current hero was already chosen, and there can only be one hero at a time. But an opportunity presents itself. Your character witnesses the strength of someone, but scorns his/her methods. So when the argument comes up that she could do better if she just was that strong, they get an offer: Think you can do better? Sure. I'll make you a hero then, if you become my wife/husband. Because sometimes heroes aren't born. They are made.

From the top of my head, some role ideas I could see for how your character could start are:
A slave who was on her way to be transported to an auction. Encounters my character when s/he tears through the escorts of the caravan and frees her and the other slaves.
An adventurer who survived the attack of a strong monster. Maybe a wyvern? Could get saved by my character.
A prince/ss in the middle of a coup. Can't think of exact details, but I like the idea of a prince/ss rising way further than their birth could forsee.
An orphan who was about to get kidnapped for god knows what reasons. Can't get more zero to hero than this, eh?
And of course, any suggestions on your end. These ideas are not mandatory. By all means, if you have an idea, let's hear it.

The idea is that they would take your character would get taken in, and given some powers from the start. Also food, and their own room for doing some chores. And if you noticed a certain lack of NSFW activities, that's because I would like to plot that out with you as well. Better than have that set in stone from the start, right?

The story itself would be about how your character would get the chance to make a name for themselves. Plot candies would be helping people, a tournament arc, travelling now and then, and of course anything we can plot out together. And personally, maybe even an answer to the question, just who or what is Yul/Yuel, and how did things turn out that way?

As for my character, I offer essentially the same character, but with the gender of your choice. The male variant Yul is straight, while Yuel is bi. If there are any questions left, send me a PM or comment here. I'll get to you ASAP.
