The Epic of Leviathan (A Mutant's Ascension)

A/N: I wanted to ask something. Someone told me to make MC adopt Eri as his daughter. I know that the MC is young but if you readers want this then I would bullshit my way through to make it. So vote for what you want...

1) Yes ​​

2) No

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

I finally reached Rumi's house and knocked on her door. Like always her door was unlocked but I still stood outside waiting for her to answer the door.

I won't enter someone's house without their consent, yes this way I can wash away my some sins. I don't know if this stuff works like that... heh!! Rumi finally opened the door bringing me out before I could indulge myself more in religious views.

"Good morning... now let's go fight once before we go on patrol!" Rumi exclaimed excited. Well looks like she isn't gonna change.

"Still the battle maniac, you need to hold yourself back sometimes" I told her while smiling.

"I held myself back until now..." Rumi said while nodding her head. I don't even want to know what the hell she is nodding her head for.

"Fine, wait for me in the usual place, I am going to change in my hero costume" I said ans she instantly became quite happy. She walked out of her house and walked towards the place we usually fought. I entered her house to get changed.

After getting changed I met her up in the forest, Rumi was already wearing her hero costume when she opened the door for me.

"So, are you ready?" I asked Rumi.

"Come! Bring it on!" Rumi yelled and rushed towards me and the iron sand stored in my hero costume rushed twoards her. Before my iron sand could grab her she jumped away towards a tree, like usual she wanted to use ot as her support to launch herself, this would have worked but I wasn't the same as before, I have become much more stronger than before.

Lightning thundered around my body and I launched a coin charged with lightning at the tree. The railgun ripped apart the tree destroying Rumi's landing spot before she could even land on it. Rumi's face showed an expression that told she knew that she fucked up.

Rumi directly landed on the iron sand blanket I made. If I wanted I could have defeated her much more easily but that would have been painful and I didn't want to hurt her at least not before when we would be leaving for patrol.

The iron sand wrapped around her body successfully restraining her. But Rumi continued struggling, trying to get out of the iron sand wrapped around her body.

"Give up Rumi, you can't break out of my iron sand" I said while looking at Rumi with a deadpan stare.

"...Ah! Fine I give up, I lost. You have become so strong, I am really proud that I have been your teacher once" Rumi spoke after sighing but right after that her face was filled with a proud smile. The iron sand was also unwrapping from around her body and Rumi was finally back on the ground.

"You have no idea how good it felt when I saw your fight with All For One. Even though I never taught you anything related to your Quirk but still made me really proud and happy" Rumi spoke while patting my shoulder.

"Well, to tell you the truth, I didn't want any of that, for me it was just a battle between life and death" I told Rumi.

"Fine... fine... let's go back. We need to report in before we start patrolling" Rumi said and started to walk towards her house. I started to walk by her side. Suddenly my phone started to ring, I pulled it out and saw it was Nemuri.

"Hello, honey~! Where are you?" Nemuri spoke and gave me a kiss through the phone.

"I am with Rumi, we would be starting our patrols" I told Nemuri.

"Oh... Rabbit Hero Mirko!! I wonder if she play roles during sex of cosplaying a rabbit!" Nemuri exclaimed in a perverted voice.

"I doubt that... I am gonna go. I will call you later. Bye, love you" I told Nemuri, Rumi was now glaring at the phone, it was pretty clear that she heard what Nemuri said.

"Ok honey~, bye, love you too!" Nemuri said and finally cut the call.

Rumi finally turned towards me looking quite conflicted. "Are you really in a relationship with Nemuri Kayama?" Rumi finally asked.

"Yes... I love her" I told Rumi.

"Your other girlfriend Momo is fine with it? I know you told me that she allowed you to date Nemuri but seriously date?!" Rumi asked completely bewildered.

"Yes, they are already good friends now" I told Rumi, this made Rumi get a far away look and nodded her head. With that done Rumi finally turned her head towards me, again.

"Do you perhaps like older women?" Rumi asked me looking slightly expentant.

"Yup..." I replied but we were already back at Rumi's house. Now, that I think about the stuff she asked me, does she like me too? Clearly thinking points me to only at that direction. If she perhaps me... then it might be easy to get her.

Her only complication might be the sharing thing. Let's wait and see what happens, we would be spending a lot of time now that we are already working as partners. I wonder what power would Rumi get if she travels to HP world?

Rumi exited her house after a few moments, Rumi radioed in the report that me and Rumi would start patrolling now. Both of us walked out of the forest side by side, Rumi always did the patrolling from the roofs and as it wasn't a problem from me we decided to take her usual route but this time it would only be along with me.

We skimmed through the city in a fast pace, Rumi was also carrying her receiver from Hero Association, that would report any emergency cases in our area. Jumping from building to building... it was fun but also boring. Not that I want someone to get in trouble but nothing happened, no bad guys so it was boring.

We finally decided that it would be awesome to race around the city, so we did just that multiple times. I could have ditched her and won by flying but that wasn't fun at all. Some times Rumi won and sometimes I won, well I won most of the times.

Finally the day was over and we were off duty, we walked back to Rumi's house. After changing back into my normal clothes I came out of her house where Rumi was waiting for me.

"Good night, Rumi. See you tomorrow" I said to her.

"You too, Reo. Call me if you find a villian on your way back! You shouldn't have all the fun!" Rumi said while walking back into her house.

"Sure, Rumi" I said finally walking away from her while waving my hand at her.

I noticed she took another glance at me and finally entered the house. After getting out the forest I took the bus back to the UA High. I really miss my own house, well I will visit mom and dad on Sunday. I know the actual reason of giving the dorms was that the school can keep an eye on the students. Well, at least that was the reason in the canon, I don't think that it has changed now.

After reaching my room I took off my clothes and got into to shower for a relaxing bath. After getting out of the bath I chatted with Nemuri for a few minutes before she had to go. Well it was bummer that I can't meet her on the school grounds except for the academic purposes. That was only rule Nezu laid down to get around our relationship.

I pulled out my notebook on which Momo have written down the theories of gravity manipulation in the simplest way possible and started to read it. After getting one point done, I practiced it, I may be OP, a broken MC but I still need to work hard. There isn't any free lunch...

After being done with it, I sneaked into girls dorm but it wasn't seemless like it always has been because Jiro saw me.

"...You aren't even here" after staring at each other for a few seconds, Jiro finally broke the silence with a knowing smile on her face and entered her room.

"Thanks a lot, Jiro" I said to her, even though they knew I sneaked around but getting seen by someone is not something I wanted. I must be getting rusty, or I shouldn't have ignored sensing people. I just thought that, no one would break in here and completely ignored my sensing ability.

As for my sensing people thing I can't exactly feel them until I concentrate on doing that or I would just keep sensing the metal in their bodies.

I finally entered Momo's room and found her sitting on the bed wearing my T-shirt which was quite big for her.

"How was your day?" I asked her after giving her a kiss.

"It was great, I had so much patrolling the city with Ryuko. She is really great, I also met and talked with Nejire Hado, she is a really really curious girl" Momo said while making hand gestures. She was really really excited, I could tell that with just seeing her huge smile on face.

I sat down by her side and patiently heard her story, after she was done, she asked me about my day and I told her. I also told her about my small chat with Rumi and Momo guaranteed that Rumi is interested in me.

Five days passed just like that and the weekend was already here. Throughout these five whole days, me and Rumi didn't find any villinas or bad guys on our patrols. It was seriously boring, I found it suspicious but Rumi told that it was quite normal in this region. Since beginning of her hero days, she didn't found that much bad guys in this region.

From what I remember Izuku and Mirio found Eri on a weekend. I just hope that Rumi can get the location from them in some meeting so that I can raid that place...
