Wizard Jaune (RWBY)

Jaune Arc fuses with some random ass soul and gets Magic and an Overpowered Semblance Soul Fusion out of the entire 'death of identity, birth of anew' deal.

Now a new person of clashing and often strange ideologies and world views, Jaune tackles the life and times of being a wizard, having really hot sisters, and being totally okay with putting his dick in them. Put two and two together: you get nine because magic is the shit.

Join a magical tale of great power, magic, knowledge, and the mythical ability to just not give a shit.

"Look upon ye, ye mighty, for it is here I grow my fucks. Witness its baren plane, unfertile soil, and grand expanse into unending desert." Jaune quoted poorly.

"So...what's with the incest?"

"Well, they're hot." Jaune shrugged.

"Yeah, but they're your sisters."

"Well, they should just not be hot then. Problem solved." Jaune frowned, crossing his arms.

"That's not how this works."

"So? I have magic, bibbity bobbity boo, now it does. Honestly, what's the problem?" Jaune asked, apathy in his gaze.

"Incest is morally incorrect-"

"Moral correctness is subjective to a group of people, and not objective to a single person or correct and singular way of thought." Jaune countered. "I could technically become my own independent thought group and think tank by claiming a plot of land and declaring myself independent. Vale wouldn't care, and I'd be leader of my new independent country, able to there by pass laws. These laws state that Incest is an acceptable and morally correct thing to do as long as nothing harmful comes from it."

"The children might not come out right. Think of Joffrey!"

"Psh, I have magic and can use a ritual to change myself into half demon or something and then fuck my sisters. Technically by changing my DNA, I'm only half related, and due to having alien DNA in my blood I'd be even more wonky in the entire 'bio diversity' argument." Jaune rebuffed.

"Hmm, maybe...maybe."

"Come, join the darkside. We have cookies, magic, lightning powers, plot armor second to one, and a dozen other thing besides."
