The Esper Devil ( Esper OC X Highschool DxD )

Chapter 4 - Spying on the enemy

Part 1

I decide to follow the trio from a good distance, I can sense presences from quite far so it's no problem

They are walking towards an old building.

I can feel more presences inside. Damn, what's going on in here?

As I check the surroundings, I look up to the window of the old building and then I see that gorgeous girl with long crimson hair looking at the approaching trio, it's Rias again!

Her beauty strikes me so suddenly that I almost forget to hide behind the trees. I'm dangerously close now, if they see me, they'll know I'm spying!

Issei signs to the redhead

"Hi buchou!"

She smiles, waves back and goes inside, the trio walks into the building, it's my time to act. I check if no one followed me and once confirmed I immediately hide my presence and walk in after them.

Woah...

The building is really neat from the inside! Did they decorated it themselves? There's no way the school provided these things.

There are voices coming from inside one of the rooms, I approach the door to hear the conversation.

"So buchou, what did you want to talk to us?" - I recognize Issei's voice

The voice of a girl who I still don't know speaks.

"...You summoned all of us so suddenly, then it must be important"

Rias starts to speak

"I had to gather everyone today, unfortunately it's not to work on our school festival project. I've received a mission involving a group of stray demons who plotted against their masters to join the Khaos Brigade, but after the defeat of Diodora, they ran away and are now hiding in this town"

"They must be a serious threat" - Kiba says

"Indeed, we believe that they may have useful information about them, so it's crucial that you capture at least one alive, that's why Rias will personally oversee this mission, right?"

A man's voice? He sounds older than the rest

"Yes, onii-sama said he needs to know if they are carrying any useful data regarding the Khaos Brigade"

I see, they are planning to hunt other demons, that's to be expected, evil existences do not respect even their equals.

But, Onii-sama? Rias has a brother? And what in the world is 'Khaos Brigade'?

I can sense the presence of 10 people inside the room, none of them are human, but each emanates a different energy.

I can recognize some: One if a full-blooded demon, must be Rias, two are fallen angels, three have half-human auras, it's Asia, Kiba and Xenovia, one is... a youkai? Really? They even have a youkai?

And three others emanate auras I never sensed before, Issei is one of them and the other, if I'm correct, must be Rossweisse, she for some reason has the aura of a demon, but just like Issei, I know there's more to her.

And even though I know there are two fallen angels, I can also sense a difference between them, one is a pure fallen, while the other is different, just like the youkai, they emanate a different aura than what a pure youkai or a pure fallen would give out.

So in total I only know 6 out of the 10, could the dark devil that Kuriko warned me about be among them?

"Shouldn't the student council help us if it's so dangerous?" - Asia asks
