It's been years since the collapse of the wizarding world. Years since the last magical was born into this world. Years since I left the manor. All magical creatures and plants have been moved into all of the properties I owned now. Being the Mistress of death prevents you from ageing. I watched it all, starting with the death of my friends, to the fall of the magical world. I watched as I became the last of my kind unknown to the muggle world as it changed and advanced.  I watched as soulmates were found and my mark formed upon the valley of my breasts to my belly button. 

Since I was the only magical alive, I was the only one connected to the mana of the world. The elves finally looked like how they were depicted in stories and legends—dressing me in a white dress for my departure. They would meet me at the new manor.  I apparate for my final walk-through.

Walking down the forgotten paths of Diagon ally one last time before I left for my new home, I reminisce in memories. I had arranged with the goblins, when they made their muggle banks, to transfer all of the titles, and monetary value into the muggle currency. It would be the first time I stepped foot into the world in many centuries. The last time I did, superhuman abilities started showing up. 

With a sigh and a last goodbye, I exited the alley and entered the awaiting limousine to the airport. The goblins made it known to the muggle world that I was a very wealthy, last remaining noble of the old blood. I had England's heroes escorting me to the airport where I would be flying to japan. 

>>>>>>13hrs 50min later<<<<<<

Once landing in Japan, I am escorted by government officials and heroes. Many thought I was a young girl still in school. I was assigned an undercover hero, named Eraserhead as my bodyguard until I was safely at the manor. Before heading out, he informed me of what was going to happen. I felt his piercing gaze on my soul mark. My breath hitched from the pleasure coursing through me from the mark. I pulled my occlumency shields up fully to not show anything, but my body trembled against my will.

A rich, velvety chuckle reverberated throughout the compartment. Twitching slightly, I shifted in my seat before looking at my hero. 'My hero? What is happening? I heard this only happens when soul bonds meet, but I can't tell if it's the hero or one of the other guards with me!' Deciding to scan his thoughts, I use legitimacy on him to see if he was. 

"Damn, she is testing me right now. First teasing me with the clothing choices to display my mark proudly. Her eyes are beautiful, though I wonder why she's been staring at me for the past 10 minutes-' I heard, before looking away. Taking my maid's offered drink, I watched the city go by. His gaze was still on me, though less fierce. 

"How long till we reach the manor? I was hoping to stop by UA to speak with an old friend if possible." I spoke gently. With the little use of my voice, it lightened and was a bit airy. Some of the people when I looked at them after didn't answer were blushing. Tilting my head slightly to the side, I face the frozen hero. 

"Did I say something wrong?" I asked him as he snapped out of his stupor. He coughed slightly as a faint blush dusted his cheeks. 

"No, we can make a quick stop there to see if they are there. May I have their name so I may call the principal of the campus?" His voice alone made me weak. 

"Nedzu" I answered before he dropped his phone. I watched his eyes widen with his mouth slightly agape. 

"Your the one he has been talking to non-stop for the past month and a half?!?!" He questioned in shock. I giggle at his reaction before nodding. I went into the story of how we met and so on until we reached the school. Nedzu greeted us at the entrance when we stopped. 

"Machiko! It's been far too long! You didn't tell me you were coming today, if I was informed I would have picked you up from the airport myself!" He spoke cheerfully as we hugged.  I giggled at his remark as we entered the school. I would be teaching here once I was settled in.  It was going to be a huge surprise for the student of the hero course. After touring the main building and training areas, we head over to the dorms.  Our conversation was cut off by the sound of explosions and yelling. My eyes catch the sight of an injured green-haired boy lying on the ground. Running over to him with the other staff and guards I start to heal him. 

When they couldn't get the blond boy to calm down or stop trying to go for the boy, I cast a body bind curse on him. With a sign, I look towards eraser with a bland look.

"They are going to be problem children aren't they?" I asked sarcastically. He stands there for a moment before bursting out into laughter.

"You'll do just fine here as my co-teacher for this class" He smirked. With a giggle, I rennervate the boy I was healing. I gently help the boy up. On the information on the scan, I conducted earlier while healing him, showed he was being injured from his quirk battling his given one. Looking him in the eye I catch him in the middle of his rambling. 

"1 out of the 8 quirks you have, though dormant till your body can handle the strain, is fighting with your main quirk. I can help you not only use them to full capacity but in unity and stability. The quirk fighting your strength enhancement is responsible for your maculate recoveries. The reason you aren't dead. 

With my quirk 'Mana', I can help. Give me your hands, close your eyes. That's it, now search within yourself. search for the orbs of colour floating within a void." I say gently.  He slowly starts to glow, and little bits of his quirk show themselves. Closing my eyes as well, I start to push my magic into him. once I'm within his consciousness I stand next to him. Looking at the 8 words of light I see his calm expression.

"Izuku" I call out. I notice the block and forced gender change. Glaring at it I face him. 

"Your gender was forcibly changed... Did you ever catch yourself liking feminine clothes? Feel pain once a month in your lower stomach? Did you ever wonder why your chest was larger than others? why you had a hard time building muscle, or was your skin more delicate than others?" I could see his confirmation before he could answer. 

" You have a block for it, I know what it is because I had one on myself before my quirk destroyed it at the age of majority. Would you like for me to unseal the real you?" I asked. I could see all of the emotions raging across his/her face. 

"Please... I want to be free." He/she spoke in faux calm. Breaking down every block I could find, I stabilize his body and shield us. Once I'm satisfied with my work, I return to the world of consciousness. Taking a step back from her, I watch as she slowly joins me. 

"Welcome back Izuku. How does it feel to be in your true form?" I ask calmly. Hearing the gasp of others I quickly took off my cloak and wrap her in it. She didn't have proper clothes on. With a wave of my hand, I transfigured the clothes she had on for proper ones.
