The Black Death (Op reader x Highschool DxD)

Horror's beginnings

Ophis: "He's also a bigger idiot."

Red: "Hey! Say that again and I'll drop you."

Y/N: "Wait, the dragons are still fighting?"

Red: "Yes, they're currently fighting in the underworld."

Ophis, who is riding on your back, moves towards your face.

Ophis: "You're going to interfere, aren't you?"

Y/N: "Are you going to stop me?"

Ophis: "I just want to know when you're coming back."

Y/N: "I won't take too long."

You pick her up and put her down on the floor.

Y/N: "Don't worry, I'll make sure to come back, I promise."

You pat her head as she pouts.

Ophis: "If you don't come back, I'll get you myself."

Red: "In short, when she finds you, she rapes you."

Y/N: "Red, just shut up. I don't want to think about that. Anyways, I'll be going now. Bye!"

Red: "Bye, Nii-san."

Ophis: "Shut up, Red."

Red: "What's your problem with me?"

Ophis: "Nothing."

You chuckle at their antics as you open up a portal in the Dimensional Gap and enter.

~~~~~~~~~~~~~~~~~~~

You open your eyes and see that you're in a forest.

'So this is the familiar forest. It's just as dark as I thought it to be.'

You close your eyes so that you can sense the energy.

'So the dragons ARE here. Wait, i can sense Holy energy, devil energy too. They must have chosen to work together to defeat the Twin Dragons. They might kill the dragons ahead of me. Hmm, how is there also dark energy here? I should check it first.'

You start walking towards the area where you sensed the dark energy.

(Mini-Timeskip brought to you by KING CRIMSON!)

After walking for a while, you arrive at a small church. Opening the door, you enter the dusty and abandoned church. 

???: "AAAAHHHH!!!"

Y/N: "A scream? It came from downstairs. Bone Guard!"

Your hand is covered in bone and a skeletal hand forms out of yours. You form a fist and smash the ground. You quickly dig through the rubble and find a young boy with a purple sword in hand.

'He's passed out. I should take him somewhere safe and leave this sword here."

You carry him on your back and exit the church. After walking for a while, you come across a small cave. You come inside and create a small bone bed. After laying him down, you notice the glowing sword beside him.

'Weird, thought I left it in the church. This means this is a cursed sword. I can sense the power of Excalibur in it, just dark and different.'

???: "Who dares to enter my cave?"

Y/N: "Hello, who's there?"

???: "How dare you address me like that, lowly being?"

A small silver-colored dragon crawls out of the shadows.
