Death's door (Male grimm reaper insert)

Highschool dxd chapter 16

A/n: Rias will not be in love with the reader. 

I found myself back in the blackness as before but this time no eyes were watching me.

???: " hello. " says a voice.

Y/n: " w-who's t-there? " I ask.

???: " just a friend. I came to warn you about something. " he says.

Y/n: " w-what? " I ask.

???: " Remember. Never be predictable. Always be unique. Even if it means getting a little weird. " he says then laughs.

(Time skip by chibi y/n drinking tea.)

I was walking towards school along with Issei, asia, and Kiba.

Issei: " Do you guys think you k or Ross's problem? " he asks us.

Then Kiba stopped and got a angry look on his face.

Kiba: " no. I can't believe I didn't notice. " he says in a growl.

We all walk towards the club and issei opens the door.

When we walk in I see a silver haired maid.

I used all of the power I had to make myself invisible to her and the others.

Issei: "grayfia?!"

Rias: " where's y/n? " she asks them.

issei looks behind himself but I sneak into the room and into the corner.

they all talked then a fire like magic seal showed up.

a blonde guy stepped through.

???: " it's been awhile since I've been here. "

Issei: " who's he? " he asks.

Grayfia: " this is Riser Phenex. A pure blooded devil. The heir to the phones family and fiance to Rias. "

After a minute he was sipping on tea sitting down in the spot I always sit at.

Riser: " excellently brewed. " he says setting down the cup.

Then he started messing with rias's hair.

It took everything I had not to attack him.

Rias: " Don't touch me. " she says standing up and stepping away " I told you I have no intention of marrying you. "

No one p.o.v.

Riser: " this is only for the good of devils-" 

then everyone in the room sensed a large intent to kill. Even grayfia was scared. They all looked and saw y/n leaning against the door.

He was looking and Riser with a death glare and Riser started to shake.

Y/n: " She said no. " he says coldly.

Riser: " who are you? " he asks.

Y/n: "Just a guy protecting a friend." He says even colder.

Then riser summoned a fire ball at y/ n and fires it at him.

it engulfed y/n.

Riser: " so he was just a human. " he sneers when the flames for down revealing nothing.

Y/n: " No I'm not. " he says behind riser.

riser swing his arm at y/n but he just caught as if it were nothing.

Grayfia: "stop." She says .

Riser: " if the strongest queen tells him even Riser must stand down. "

He stepped away from y/n but he still had his cold look.

Y/n: " who are you? " he asks looking at Grayfia with cold eyes.

Grayfia: " Grayfia. A servant of the gremory house." She says.

Y/n stepped away from them and leaned against the wall.

Rias: " Riser. I challenge you to a rating game. " she says.

Y/n: " I'm leaving. " he says walking towards the door.

Then he looked back at riser.

Y/n: " Riser phenex? If you ever anger me again I will fight you. " he says walking away.

He walked away from the club room and all the way back to his house.

Y/n p.o.v.

???: " Good job. You listened well. " says the voice from my dream.

Y/n: " what now? " I ask.

???: " we wait.
