I am secretly a 12th Dimensional Eldritch God

After resolving the arranged marriage between Rias and Riser. My life once again returned to the usual monotonous days and once again I am contemplating if I should go to Heaven or Church to entertain myself.

Pretending to be Biblical God or his son as a change of pace might be fun. Just to watch how they would react.

Feeling indecisive, I turn to my ever loyal caretaker.

"What will you choose? Yes or no?" I asked with the look of boredom being very apparent on my facial expression.

"Eh?" Ravel was startled from watching the soap opera on the TV. "Uhm… Master, are you thinking about razing the Heaven or Church again?" She asked, already knowing my line of thoughts.

"No." I replied as I am not really trying to kill or destroy anything. Just a harmless prank… Maybe.

Ravel narrowed her eyes at me with suspicion before she said no.

"Tch, you are no fun, Ravel." I grumble and then turn my eyes to the boring soap opera playing on the TV. There's not enough chaos, despair and grief in it to be enjoyable to my now Chaotic Evil aligned mind.

"My apology, Master. However, I still like my peaceful days and I want it to last." She explained.

Apparently her devotion isn't enough to the level where she can butcher her own family without batting an eye if I order her. Well, she is taking baby steps. Sooner or later she will get there.

"Then, you wouldn't mind as long as it's not this world, right?"

"Hmn? If it's not my world then… maybe I wouldn't mind?" She said with uncertainty.

For a Devil, her moral is surprisingly strong. But nothing that I cannot corrupt though.

"Then, let's go into another timeline, not our own. There we can cause as much chaos without it affecting this world." I said, making my mind to both find myself some entertainment and train Ravel to be my proper follower.

"Eh? A-Alright, Master."

———

In an alternate DxD world timeline.

"Oh! Ooohhhh! Lucky find, a fellow reincarnator." I said after checking on the development of this timeline.

"Reincarnator?" Ravel got curious and asked.

"It's nothing. Anyway, let's go and meet yourself in this timeline. I already have a good feeling about this." I said and pointed in a direction, ordering Ravel to march forward while I rested my neck on her two soft and springy cushions.

Moment later we arrived at Kuoh Academy. The class was already in session as we strolled in without being noticed by the security staff.

Immediately I can see the reincarnated MC sitting by the window boredly staring out from his class and spotted us, more specifically on Ravel.

"Is that the person you are looking for, Master?" Ravel inquired while evaluating the MC visually.

"Yes." I smirked while looking at the MC's face morphed into shock before terror painted his face

"Hmn. Classic Observation skill. It's a double edged ability since it may pierce through veils and someone might unknowingly peek at something they shouldn't…" I mutter as the MC immediately writhing and claws his face and eyes out.

"Let's go." I ordered as panic ensued in the classroom after what happened to the MC.

"Y-Yes!" Ravel panicked and tried to hide her grimace after witnessing such a macabre sight.

With reincarnated MC A.

What is that! What is that! What is that! What had I just seen! Ack! It felt… alien! Disgusting! Terrible! Like something slick and slimy is molesting my brain and carving weird things into my head! Burning it into my memories.

[Warning! Host mind had polluted my information from higher dimensions.]

[Gamer Mind is trying to negate mental pollution.]

[Negation failed. Reason… ERROR! ERROR! ERROR! Unable to comprehend. Existence exceeded the administrator's authority.]

[Gamer Mind is trying to perform damage control…]

[ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR! ERROR!]

[Gamer Mind unable to resist mental pollution. Gamer Mind is being corrupted. Mental containment breached! Gamer Mind has been disabled.]

That is the last thing I heard before I felt my brain reach its limit and explode.

In the classroom.

The classroom had been evacuated minus a few devils who are nervously pacing around while Asia is trying her best using Twilight Healing to heal Issei however unfortunately to them, Issei isn't injured or sick. His head was overloaded with a large amount of information way beyond his capacity. All she could achieve is to heal the eyes he gouged out.

Then Issei briefly woke up which made everyone feel relieved.

"Issei!"

"Issei-san!"

They called but then noticed something odd as Issei's expression is that of resignation. Then everything went to hell.

"What a shitty way to die…"

Issei uttered before his head just suddenly exploded. His brain was bloated and ruptured with indescribable alien-like tumors throbbing inside.

"AAAHHHHHHH!" Asia shrieked in shock before she fainted after seeing Issei's head burst open in front of her eyes, showering her with all its twisted glory.

Rias fainted soon after while the remaining ones, Sona, Akeno, Koneko, Xenovia, Irina, Ravel, Morgan Le Fay and Kiba paled and struggled to hold back their bile that rolled up their throat.

Then they heard someone walk into the classroom after they heard the sound of the door being slid open.

"Ah, we arrived a little too late. It's a bummer. I wanted the first seat to watch what happened. Well, I can simply rewatch it later though." A male masculine voice was heard as they turned around to look at the unknown intruder.

"You! You are the one that killed my Issei!" Xenovia immediately summoned both Holy Swords and attacked the intruder.

"It's rude to suddenly attack out of nowhere. Besides, I didn't kill him. Intentionally that is. He shouldn't try to peek at me using his ability that carelessly. Can you blame me when he tries to court death on his own?" The intruder said.

"I don't care!" Xenovia roared and continued with her attack.

"Hmn. Then you can blame me for trying to defend myself either then." The intruder held his paw forward before the ground suddenly consumed by darkness from which a few chain spears made of darkness shot out from.

Xenovia confidently swatted her Holy Sword on the chain. However, instead of swatting away the projectiles. Her Holy Swords suddenly shattered like porcelain glass by a sledgehammer. It shattered into a thousand pieces.

"How… not just Excalibur Destruction. But also Durandal?" She fell down to her knee in shock and disbelief.

"Well, your artifacts were merely something that was forged by the Fairies, not to mention degraded by the hand of a human. What do you expect?" The intruder scoffed before looking at the others. Though, they were busy looking back and forth between Ravel and the other intruder.

"Did you see that, Ravel? It's your other self that has been manipulated by the power of this Issei to fall in love with him just like the other girls. It's the power that forcibly alters your affection although he still needs some effort to raise it up."

Both the intruders were in their own world as they talked. However, from the way the female intruders were addressed with the same name as their own Ravel. It confirms that there are two Ravels!

"Is that really the case, Master?" The other Ravel asked with a look of disgust in her tone as she stared at Ravel.

"What? Do you think I would lie to you?"

"N-No! I won't dare, Master." The other Ravel quickly corrected herself in a panic.

"I thought so." The intruder said before glancing at them. "But still, you already see how one of your friends failed to even be a challenge to me and yet all of you are still thinking about fighting me? Truly, the shitty parasitic System is always an annoying thing to deal with."

The rest of the deceased Issei's harem and Kiba prepare to fight and avenge Issei's death while the feline intruder looks unimpressed and immensely bored.

"Dispose of them, Ravel. They should prove an adequate opponent to you since they are stronger than their original counterpart.

"Y-Yes!" The other Ravel replied immediately and stretched her right arm out before she gave her warning, "I'm sorry but you all are trying to attack my Master. Dark Blaze!"

A black all consuming flame appeared and wiped out everyone without any resistance.

"Hmn. Good, let's go home." The feline intruder said before they both disappeared engulfed by darkness.
