(This is Morpho Knight's voice when Hiro is in Morpho Knight form he and Morpho speak together like dbz fusions)

Me: Prepare yourself minotaur for we are Morpho Knight.

Elsewhere

In the dark caverns of the underworld exist a realm ruled by the mesopotamia goddess of the underworld Ereshkigal.

She has had a great relationship with the reaper butterflies the helped her gather souls and send them to their new life but after their disappearence the blonde goddess grew sad the reaper butterflies had the ability to travel realms at will because of the ties to the dead the reaper butterflies were known by all being that were affiliated with the dead but to Ereshkigal they were more than  friends they were her family and when they were gone she felt alone abandoned thinking they her left her alone until she heard that they were eradicated.

Her heart felt heavy her friends those godly butterflies of death she considered family were all dead but what killed them they were strong enough to even kill gods if they choose to so what happened to them.

After so many years Ereshkigal felt an all too familiar arua a reaper butterfly as emerged.

Ereshkigal: They're still alive maybe my friends are alive I will have to see for myself.

Morpho:Hiro I'll guide you through our abilities summon your sword.

I focus and all of a sudden an orange sword appeared in my hand.

The minotaur Grimm charged at me but I was faster I caught it with a slash combo.

It tried tried to use it's own sword against me but I knocked it away.

Morpho Knight (Hiro):This won't be enough to defeat us.

Me and the minotaur Grimm continued to clashed with one another I need to end the quickly if it gets away and recover it could kill someone else.

Morpho Knight:Let these flames consume you.

It jumped back to avoid the flames from burning it to death.

Morpho Knight:So you aren't as mindless as the other Grimm.

I can't let it escape I have to end right here and now.

Unknown to hero a certain green hair esper was watching the fight impressed.

Morpho Knight: It's starting to slow down now.

I knock it into the air with upper calibur.

I summon a second sword.

This is it the strength I need to protect.

Now it's tried time to finish.

Morpho Knight:I have to thank you because of my near death I wouldn't have met Morpho and never became Morpho Knight so thank you I give you a warrior's death.

I started to channel all the fire into my sword.

Morpho Knight:This is the power of the reaper butterflies Burning Calibur.

Unknown to Hiro all the students and Headmasters had witnessed his fit with the Grimm minotaur and we're in awe especially a certain blonde King of Knights herself but she was also surprised by his attack which reassemble her noble phantasm Excalibur he called it Burning Calibur.

Morpho:Hiro we have guests it seem.

I turn around and see the entirety of Union Academy looking at me in shock they must have seen my fight with the minotaur Grimm.

Me:so how much of the fight did you all see.

Ozpin: Nearly all of it but who might you be.

Me:We are Morpho Knight but you know me by another name.

I the remove my armor to everyone's shock to see that it me.

Me:Hiro Shizuki nice to meet you all.

Sirzech:What do you mean nice to meet you all you've been at our school for months now.

Me:Yes but it appropriate now the I'm reborn now you see I died and was reborn as a Butterfly a Reaper Butterfly to be exact.

Ddraig:A Reaper Butterfly!?

Me:Yes you know of them.

Ddraig:Reaper Butterflies have great ties to the dead like the grim reaper them collecte the souls of the dead but what they are known for is their immense power the souls they absorb become a part of them they they're strong enough to kill gods with ease but what frightening is what cause their extinction.

Me:That I don't know not even Morpho knows.

Serafall: Morpho?

Me:yes she the one who gave me these powers.

Morpho: Hello everyone I am Morpho Knight or as Hiro calls me Morpho , and yes I am the last remaining Reaper Butterfly in existence Hiro here is my host and successor.

Issei:Why give your powers to him he's a loser.

Morpho: Because he doesn't desire power for fame, fortune,or even women he desires it to protect I was there when his village was destroyed the look in his eyes said it all he was broken because he lost everything friends, family all of it you still have people to care about Hiro did not he had to grow up without a family.

Morpho:I watch him grow up and wanted to prevent what happened to him from happening to others he wanted to become stronger not for himself but to prevent others from losing everything like he did.

Tatsumaki:So you're saying you picked Hiro because his suffering lead him to becoming your host.

Morpho:No it's more like how he keeps his head held high even after everything he's been through his determination his will to go on for others that's why he is the perfect host and has the right to be my successor. Because he found the strength to go on through the pain of lost.

Everyone was speechless at Morpho's words they couldn't say anything Uni could only stare at Hiro realizing he's been longing for love when he had none growing up.
