I am secretly a 12th Dimensional Eldritch God

A few days later.

I noticed today was April 23 already when I was watching the news during breakfast.

"Right, today is the day Riser comes to meet Rias right?" I mutter to myself while feeding myself a grilled salmon as the rest of the girls eat their scrumptious breakfast prepared by Sakuya as always.

Asia as usual attends school and enjoys her time. Sirin and Sakura however, got addicted to gaining power. They are always begging me to send them back to the dungeon so they can get stronger and unlock more of my power.

I am happy they get the drive to grow stronger. However, that left me with my usual problem again. I am alone and bored and might do something crazy to rid my boredom.

"Maybe I should get involved… For fun of course." I said and made up my mind.

"Hey, Asia. I'm gonna tag along with you to class today." I said, informing her of my decision.

"Eh? Ah! Why? T-The Class Observation day is still months away." Asia panicked for some reason.

"No. It's not that. I just have a feeling something interesting will happen and I want to observe." I corrected her which calm her down immediately.

"Oh. Alright." She bobbed her head and get back to eating her breakfast.

Today was an important day for Issei. After what happened last night after Rias suddenly barged into his room and he learned about her engagement. Issei were committed to help her break off her engagement!

That's until when Ddraig inside his left arm suddenly warn him of a powerful and dangerous entity nearby and told him to escape.

Issei turned his neck towards the 'dangerous entity' he saw a familiar black cat, unnoticed by the normal people, roaming around the classroom before it wander off to the hallway and left.

"Nah, let's not be bother by that." Issei replied with a deadpan face.

Issei already saw what happened to those who messed with the unknown god. Im fact, his two friends, Matsuda and Motohama had yet to be fit to return to school and probably still tied up in the psych ward, screaming about the nightmare that tortured them in their sleep. Something about buffed and ripped mascular magical girls or something.

This give Ddraig a surprise as he lived for quite long and never heard of this mysterious unknown god.

———

For Rias and Sona.

Sona was the first to learned that the unknown god is wandering the hall of the school like a terrifying monster from a psychological horror movie that made them fear to even walk out their classroom and been shaking in fear the whole time.

There's nothing the two can really do even after they informed their elder siblings. As long as the unknown god did nothing that can provide them a reason to retaliate. The unknown god can do all he wants and there's nothing the two Satans can do about it.

The two almost passed out with foam on their mouth along with the other devils when the saw the unknown god in his cat form, wander outside the classroom hall like the monster in horror movie stalking it's prey.

Back to me, the mc.

I wandered all over the school to check it out and marveled in it's architecture. Those Devils really splurged a lot of money on this academy. Although, compared to what they usually build in the Underworld. This academy building is just way inferior.

My little adventure brought me at last to the Occult Research Club's clubrooms or house really since they have the whole building for themselves.

I found where the trap vampire were hidden, sealed behind a storage room and decided to check him out.

Using my shadow, I infiltrated the room and bypass the alarm and seals at the door and entered the room.

Inside is various boxes and stuff stored away. It's what you expect to find in a storage room. But one of them is an unassuming box laid in the middle of the room with someone hiding inside.

An idea came to my mind as I silently approached the box.

"Boo!"

"WAAAH!" The occupant inside the box screamed like he got sneak up by a ghost.

"Who-who-who is-is that?!" A feminine voice screamed from inside the box.

"I am Death. I come to take your soul, Gasper Vladi!" I replied with a somber tone while holding back my laugh and rolling on the floor.

"WAAH! Don't kill me! I still wanna live! Rias Buchou! Help me!"

That's it, i can't contain my laugh and laughed uproariously while smacking the floor. I didn't know pranking someone would felt this much fun.

"Eh? Who are you?" The occupant of the box finally realized he had been pranked and peek at the holes on the box to see a black cat laughing and smacking the floor with it's paw while rolling around uncontrollably.

It took a while for me to stop and when I did, I answer his question.

"Me? I am a talking black cat, secretly a 12th Dimensional Eldritch God, here to bring upon the world death, destruction and chaos." I replied very seriously.

"Mou! Stop playing with me and answer my question. Rias Buchou should have sealed this room. How can you enter?" He said.

"Well, I am serious. Part of it, that is. I am a talking black cat. Believe it or not."

"Uhm. I believe that part." He said, not yet aware that he should be socially awkward. Or perhaps that only applies to another humanoid?

"Well, anyway. I am just here to check out something. Since I already achieved my objectives, goodbye." I said and then left with the same way I enter the room.

After the school session ended. Rias and her peerage gathered in their clubroom awaiting for someone to arrived.

Rias still worried about the unknown god considering she just learned that he meet Gasper for some reason. Other than pranking her poor bishop. It did nothing else and then left.

Then Grayfia appeared.

"It's time, Milady."

"Haah… alright. Since everyone is gathered here. There is something that I would like to in–" Before she could finish her words, a magic crest of a pillar house appeared in the room with bright yellow fire to appear and filled the room with heat.

From the fire, a blond Devil wearing expensive maroon blazer appeared.

"Hello, my beloved Rias."

"Riser Phenex." Rias said with shock and disgust hidden in her voice.

"Indeed, it me, Riser Phenex." The man said with prideful look before his eyes shifted to another corner of the room. "By the way, who are they?" He points.

At the direction Riser point is a black cat sitting on Asia's lap while being served refreshment by Sakuya which looked exactly like a mini Grayfia.

"Hello." Asia waved with some shyness when everyone in the room directed their gaze on her.

"Please. Don't mind us here and go ahead. We will bother no one and be just a silent spectator." I replied while taking another sip of my tea using my shadow tentacle.

"Who is that talking cat and the Grayfia look alike?" Riser questions the ridiculous looking situation and so does the rest of the people in the room especially Grayfia who look very shocked and with a wide bulging eyes at Sakuya.

"Ahem, we already exceeded the words limit here. So, I will answer that in next chapter." I replied and everyone look even more confused. "Okay, cut!"
