Takes place the after "Nightmare" this will also lead into the next main chapter.

*Izuku POV*

I was at the residence of the Emiya family today.  Why?  Cause I want to make myself stronger.  Strong enough to protect the girls that put their affection towards me.  Strong enough that even though I can't be a proper hero I'll be theirs.

As I knocked on their door expecting Kiritsugu or Irisviel to open it, but I was surprised when the person I wanted to talk to appears.  I quickly bow before making my request.

Izuku: Please train or teach me to use magecraft so I can use my reality marble!

Shirou: Why?  I've already told you I won't allow someone who is like a brother to become like me.

Izuku: I can't help it I've always wanted to be a hero.  While I know I can't I'll keep singing but I want to be the hero of the women who love me and who I love back.

Shirou: *Sigh* Come in let's at least see what your Element and Origin are.

*Shirou POV*

As we get to the living room I see Mom, Dad, and Illiya as if they were expecting this.  I just sit and motion for Izuku to sit. I then proceeded to have him do a very basic miracle to glimpse his element and Origin.  As it activates I see what I thought was a simple and easy miracle makes Izuku sweat.

Shirou: 'Are his circuits that degraded from lack of use?'

Izuku: I see nothing and just a dark void.

I don't understand.  While I'm a rarity being an incarnate with an element and Origin outside of the 5 known ones I've never heard of that.  As I look at my family Dad is as pale as mom and Illiya are normally.  The two women look even paler then fresh snow if that was possible.

Shirou: Care to fill us in?

Kiritsugu: As you know Shirou there are five elements: Fire, Earth, Wind, Water, and Ether.  You Shirou are a rare magus who has an element outside that.  Even rarer as an incarnation with a matching element and Origin.

Irisviel: There are also two imaginary elements.  The first is Hallow or imaginary numbers.  Basically "that which is possible but not in the plain of existence".  One of you girlfriends Saukera I believe is in this category plus water.  Izuku seems to be the second of the two.  It's called nothingness.  Simply "which is not possible, but materializes".

Shirou: Come on mom there is nothing going on between me, Rin, Saukera, nor ludvia

Izuku: Explains why that world seems to have nothing in it.

We all look at Izuku like he just grew a tail.

*Time skip brought to you by chibi Izuku explaining his reality marble*

I can't believe it he saw Saber, Archer, and Gilgamesh.  But why is he seeing heroic spirits in his reality marble?  According to Izuku they had the appearance of ghost yet their noble phantasms seemed physically there.  Could it be like unlimited blade works but that should be unique to me and him.  Even within UBW noble phantasms are ranked down in terms of power.  Yet to Izuku when he saw Gilgamesh's key to the gate he glimpsed Ea and according to him it gave off such a dangerous feel he didn't want to get near it.  I can't even replicate Ea, and even if I could what Izuku said doesn't make it sound weakened at all.

Izuku: Hey Shirou what's the throne of hero's?

Now it was my turn to go pale.  Mom fainted at that, and dad looked like he wanted a drink.  Illiya said something bout air and left.

Shirou: How do you know of that?

Izuku: It's bouncing around in my head.

It can't be!  It seriously can't be.  I would would have to witness that world first hand to confirm it, but now what to do with Izuku.

Shirou: *Sigh* alright I'll help you get better at magecraft so you don't kill yourself trying to activate whatever your reality marble is.  Cause I really don't want to explain to your girlfriends why you died.

Izuku: Thank you so much! *bow*

Shirou: But first we need to find out how many magic circuits you have and how much mana your body contains.

As I activate the miracle Rin taught me I go pale once again.  This Emerald cinnamon roll has reserves the higher ups in the clock tower would be envious of with an output to match.  How?!  He never used them till recently.  And the number of circuits rivaled Ludvia's.  Just what kind of monster is this kid?

Shirou: I won't tell you what I learned, but i know why you started having a nose bleed when activating your circuits.

Izuku: Why?

Shirou: To put it simply and bluntly your a monster in the world of mages.  When you use your mana it damages your body cause it's not use to it.  To make an analogy it would be like trying to drain the middle of the ocean with a large straw.  Hell if you had my reality marble you could keep it open for days if Gaia or Alaya didn't try to intervene.

Izuku: Who?

Shirou: Gaia or the will of the world.  Tries to stop anything unnatural from taking place example being it will try to break a reality marble from the outside.  Alaya short for Alayashiki is the collective unconscious of mankind.  Simply put the will of mankind to survive.  If something threatens that Alaya sends in counter guardians to kill all those involved in that threat.  We REALLY don't want them summoned for you for example.

Izuku: *gulp* Why?

Shirou: Everyone who ever been in contact with you will be killed.

Upon hearing this cyan lightning starts arcing around Izuku.

Shirou: 'Well we at least now know his trigger for his magic circuits'.  Izuku calm down it was just an example.

As the mana in the room dies down I notice it was just me and Izuku still here.

Shirou: let's get started come with me.

*Izuku POV*

I followed Shirou to a dojo of some kind in their house where he proceeded to help me get better at mage craft.  Though it was only reinforcement with mana in my body at the moment, still after bout an hour I had a bad bloody nose with some blood leaking from my ears before Shirou told me to take a breather.  Fuck does this exhaust me.  By the end if today's training I no longer get a bloody nose just activating my circuits.  Downside I feel like I could sleep a week.

Izuku: Thanks Shirou I'll come back tomorrow.

Shirou: Don't worry about it if you miss a day here.  Just practice what you currently know till it's almost like breathing to you.

As I head back to UA. I wonder what the hell is my world about.  Shirou seemed shocked at the mention of the throne of heroes heck even Irisviel fainted at its name.

Getting back I'm greeted by Ocha who hugs me.

Ochaco: Hey Dekiru how've you been?

Izuku: Good, how bout you Ochaco?

Ochaco: Good.  Though you gave us a scare when you disappeared without letting anyone know when to expect you back.

Izuku: Sorry I was hanging out with Shirou and Illiya today, and I sort of lost track of time.

I don't know why I did what I did next, but I leaned down and kissed Ochaco.  She started to panic for a bit before she wrapped her arms around my head and neck and returned the kiss.

Ochaco: 😳😍 Izuku what was that?

Izuku: Can't I kiss one of my girlfriends when it seems appropriate?

Ochaco: No....I mean you can just it was my first kiss so I was just surprised is all.

*3rd Person POV*

Near the stairs just outside what the young mage and zero gravity pair could see were three other members of the harem who saw the goings on.

Mina: Still happy I got his first kiss 😏.

Momo/Midnight: 'The V-card shall be mine!'

Just then izuku's phone rang snapping everyone out of their personal thoughts.

Izuku: Hello?  Oh hey Shoto.  Yes I remember.  Cool I'll see you tomorrow.

Just then the rest of the harem comes into the room including Yu.

Izuku: So I'm hanging out with Shoto tomorrow so I won't be around to much.  So to make it up how bout I sing for you all.

Girls: Yes please!

*Izuku POV*

Izuku: Oh by the way Yu why are you here?

Yu: 😞 Can't I drop by to see my boyfriend?

Izuku: Of course your always welcomed.

Yu: Yay!  Plus Nezu offered me a job as an assistant teacher.

I quickly get my guitar before coming back down.

Izuku: I can only do one song cause I'm really tired if that's ok.

The girls just nod as I smile.

Izuku: I wrote this one for you all, it will be on our album but keep it a secret for now, ok? That means you too Mina.

I smile as she pouts playfully before putting her phone away.

(Found this song recently through an amv thought it would be good to show how much he cares for the girls)

As soon as I stop singing and put my guitar down I get tackled by 7 bodies.  As I look down I see the girls starring up at me before saying in unison.

Girls: I love you Izuku/Izu/Zuzu.

Izuku: I love you too girls but now I need to sleep.

I watch as they did rock, paper, scissors to see who stayed with me tonight.  It ended up being me and Yu.  She quickly goes off to change as I do the same in my room.  She eventually comes back with a very thin tank top and shorts.  Covering just enough to be decent yet teasing at the same time.  We soon cuddle up as I quickly fall asleep.

Yu: Boo and here I was hoping to entice you with my body.  Oh well sleep well Izu.

Even asleep I felt someone kiss my forehead before I drift off back to that world.

A/N And so with this I'll get back to the main story please look forward to Dinner at Todoroki's.  I'll be waiting on the beach.
