Issei's POV

She suddenly run near the fountain which confused me, but when she turn herself to me with her hands is behind her back with the smile of a person who has a happy time.

It makes my heartthrob.

'Yuuma chan is really pretty...'

"Say, Issei Kun"

She said to me which I turn serious.

"Do you mind doing me a favor to commemorate our first date?"

She said while taking one step closer to me.

I don't know how to answer.

'C-could she be asking for a ki...'

"W-what kind of favor..."

I said, I saw her looking down with her body slightly crouching. I couldn't see her expression but I think she was shy.

Yuuma chan slowly raises her face, but her expression suddenly changes.

"Could you die, please?"

"What?"

I widen my eyes while looking at her.

"Wait, I... I think I....huh?"

I said while I put my pinky into my ear as if I heard something wrong.

"Sorry, yuuma chan, could you repeat it again?"

She steps closer to me until she places her head behind my ears and then whispers.

"Will you die, please."

"Ah."

She smiled evilly until....

I..I see it...

I definitely see it!

It was for an instant but I definitely see real boobs!

Her boobs!

Yuuma chan's boob!

Wait that's not the point here!

I felt my whole body give up, I fell to the ground as I saw Yuuma chan turn older and a thong and some cloth that only covered her nipples, but what made me terrified is her black wings that suddenly grow at her back.

Her way of clothing...isn't this the way people called exhibition?

No, this isn't a time for that!

W-what is happening!

"Although it's fun playing with you even if it's short-lived, innocently being lovey-dovey with you was fun."

She raises her left arm and started to play with the gift I gave to her earlier.

"I'll take good care of this gift for you... So...."

I stretch my arm wanting to reach her, I was confused, I want some explanation.

What is happening?

What's with those wings?

How did that spear-like thing appear in her hand?

I want some answers!

"...please die."

She threw the spear at me. It was too fast that I couldn't react, I thought it would stab me but something powerful destroyed the spear that Yuuma chan threw.

Yuuma chan seems shocked, I was confused wondering what had just happened, the spear that just appeared in her hand and threw to me shattered like broken glass right in front of me.

It didn't pierce in my body...

I don't know what the hell is happening!!!

"You sure do enjoy your time with him, right, Fallen Angel."

Yuuma chan was so angry and looks up at the sky.

I also look up too and saw...

A beautiful red hair swaying together with the wind, it looks like blood, her arms are crossed together underneath of her boobs, her blue eyes that full of authority and ruthlessness.

She looks angry as if something she doesn't want to happen, happens.

What she wears is something I wouldn't see in school...

What I notice more is her bat-like wings albeit with no skin.

"Gremory...senpai?"

"Gremory household...what does the Heiress of Gremory is here."

Yuuma chan angrily as she creates another spear that looks like a light.

"The one you're about to kill is the person I put my eyes on."

W-what is happening...

*

*Rias POV*

" Ha! So what if you put an interest in him, he is a threat to us fallen angels!

Don't go putting your nose here princess of destruction!"

The fallen angel said to me... I have failed to investigate this being, Due to following Yato back then, We forgot this Fallen angel who's targeting Hyoudou Issei.

If what she said is that he is a threat to them, it will be the more I needed for him to be my peerage.

What I felt isn't wrong, I must have hyoudou Issei.

The fallen angel shoots two light spears at me.

I was annoyed and angry, why did this happen at this time!

Akeno and Koneko are still not here, I have to buy some time.

If I used my strength here, I'm afraid I would destroy this place.

"Why don't you attack me ha!?"

"I have no time to waste my magic to you."

"You!!!"

She create several light spears at once which I was surprised at.

'This is the first time I saw a Fallen Angel that can create many light spears at the same time...

I dodge every light spear she had thrown at me.

"I guess, I have no choice."

I just hope that I won't destroy this place...

I started to use my magic retargeting the fallen angel in front of me.

"I'm afraid I won't allow you to do that, heiress of Gremory household."

"!!!"

Another fallen Angel!?

He wore a trench coat and a hat, he looks like a middle-aged man but.

He attacks me behind my back!

He thrust his light spear which I don't have time to dodge.

Oh no!

I waited for the spear to pierce at me, however, I widen my eyes when that said Light spear has been stopped.

Something is blocking the light spear to thrust at me.

I saw a transparent wall where it blocked the light spear.

What...?

"Oh, my~ This person is just a passerby and happens to witness such...supernatural things, Care to enlighten me of what is happening here?"

I was too shocked at the wall that looks like a barrier to me that I couldn't react to the person who spoke.

It didn't take time for me to come back to my senses when the middle age fallen angel spoke.

"And who are you?"

Said the middle-aged man who's wearing a trench coat with a black fedora hat.

"Who I am is none of your concern, what you need to know is what will happen next if you arrogantly act like you are superior, trench guy."

"Heh, we'll see."

I finally took notice of a man wearing a long gray coat, white long-sleeve over a brown best, black brawler hat, black pants, and shoes, he looks like around his twenties.

Pale ash blonde hair and yellow eyes, his skin is pair white with a masculine body.

He looks like a gentle person but his eyes are different which is so distant and cold. He looks like a person who won't show mercy to those he doesn't like.

But what confused me the most is how he somehow has the same aura of a person I knew when he turn serious.

Back then, it was just temporary when he suddenly leave for some urgent mission that turn out something unexpected to us...

And his aura is just the same as him

But he isn't that person...

Who is this mysterious man...

What is he doing here?
