Mikasa Ackerman X YYH Male Reader: Love Unbound

Y/N is a young teenage demon warrior with a human appearance. Having achieved the power and skill of an upper level S-Class warrior thanks to the immense training you received, you prepare for the demon world tournament in hopes of becoming a ruler throughout all of Demon Realm. Under the watchful eyes of Mukuro, you become a valuable ally alongside Hiei, a demon warrior who wields a Jagan eye.

You and Hiei prepare for the next demon world tournament after Enki was declared the victor. With much effort and dedication, you develop powers capable of rivaling that of Mukuro, thus surprising Hiei and getting him to compete with you over who the strongest demon warrior is.

However, while your training, you gain a new power that allows you to create 'bridges' between worlds outside of your own. Upon doing this, you accidentally create a portal into another world that's unlike your own. This is where your story begins.
