The dimensional gap was the birthplace of Ophis, the Infinite Dragon God, Great Red, the True Dragon and Trihexa, the Beast of Apocalypse. No one can survive in the Dimensional Gap without magic, demonic power or other protection. Anyone without such protection dies within seconds of being exposed to the "Nothingness" within the Gap.
And in that place that was dangerous to others were two people lying floating in the dimensional gap. Both men and women were naked not wearing any clothes on their bodies.
The two people were Shiro who had come out of Nothingness Slime God mode and Great Red or who is now Deisy which meant dream.
'This is a new experience for me to have sex in the dimensional Gap.' Shiro though.
If others found out they would probably vomit blood because no sane person would have sex in the Dimensional Gap.
[Master Shiro, are you sure you still want to relax] Kuroha suddenly said to Shiro.
"Why? Is something wrong?"
[Don't you want to save your friend who is being forced to get engaged?]
Shiro opened his eyes wide after hearing Kuroha's words. He then used Clairvoyance and sure enough Rias was currently in the underword getting engaged to Riser. Luckily Kuroha remembered him otherwise he would have forgotten it.
'Hmmm it's a shame that I missed the match between Rias and Riser but isn't this good! At first I thought of training her so that Rias doesn't lose to that chicken but with this shouldn't I be able to make a fuss in the underword and make a name for myself?'
"Hey Deisy wake up" Shiro wake up the woman who was lying on top of him.
"Hmm... What's wrong?" Deisy asked rubbing her eyes.
"Well I have business to attend to."
"What? What do you need to do?" she asked with interest.
"Well I'm going to make a fuss in the underword do you want to come with me?" Shiro said nonchalantly.
"A ruckus?! And you to be pulling me along?"
"Hehehe that's good."
Underword would truly be shaken by the two strongest existences in the World.

- Underwords -
Rias was in the changing room wearing the dress they chose for her. She had dead eye on her face as she prepared for her engagement party.
She felt that today was the worst day for her. Not only will she marry a disgusting person but riser also said that after the party was over, he would make her his woman by taking her virginity.
She suddenly thought of a man who appeared in her life even though it was really short. He was really shameless, lewd, and annoying but he managed to make her fall in love with him. Not only her, he also managed to make her friends Sona, Akeno, Koneko and Sona's peerage fall in his charms.
Rias really wanted to at least say goodbye to him.
Looks like her friend Sona will be lucky to be his partner given her closeness to him.
"Rias-sama it's about time." A waiter reminder her.
"...Yes." Rias answered monotonously.
Rias goes towards the party she pretends to enjoy but her acting was easily noticed by someone experienced.
Sirzech who saw his sister's behavior sighed he also couldn't do anything to help his sister.
Then he heard an explosion sound and the door suddenly flew towards Riser who was standing beside Rias.
Then a very handsome man with blue hair and blue eyes crossed the door with behind him a beautiful woman with red hair and black eyes. It was clear that it was the man who kicked the door.
"Hey~ Hey~ Rias aren't you going to invite me? I'm sad you know after we've done so many things like this and that." Shiro deliberately caused a misunderstanding with his words.
The ORC and student council who saw him became surprised and delighted.
"Shiro!?" Rias was happy to see Shiro but she also had hope after seeing him.
"Yeah yeah I'm Shiro."
"Bastard! How dare you mess up my engagement!" said Riser who got up after being hit by the door that Shiro kicked.
He then threw a large fireball at Shiro.
Shiro who saw the fireball just erased it. Seeing it everyone was stunned.
"Huh with whom are you talking mongrel!! Kneel!" Shiro said sending pressure.
He then used [God King Ambition] and [Great Demon lord Ambition].
While [Great Demon lord Ambition] is an ability that is able to emit an aura that can cause a person to go crazy or even die after feeling it is different with [God King Ambition].
[God King Ambition] has three abilities, namely:
[Supreme Aura]
Makes the person who feels it submissive to the user and can even make him a loyal slave.
[Apocalypse aura]
Creates destruction and various destructive phenomena occur if released.
[Absolute orders]
Users can impose unbearable orders on all kinds of existence, natural and supernatural, life and death. Although commands are usually spoken, the intention of the user is most important. They can impose complex commands with one word, through certain gestures or acts of sheer volition, without hesitation bending anything and everything to their liking.
The pressure goes all the way to the underword. Shiro withheld the power of [Great Demon lord Ambition] because otherwise everyone here would die. He did not direct his pressure on SC and ORC members.
Everyone in the underword are on their knees. Be it the fallen angels, the demons, the Dragons all kneel over after they heard Shiro.
The Maou were also forced to kneel by command. Shiro walked towards the sifted Raiser and stepped on his head. "Now speak"
"W-who the hell are y-you?!" Raiser after with fear he even peed himself.
"Me? A GOD... Disappear" Shiro used [Erasing God Zeno] completely erasing Riser from existence.
"How dare you touch the woman i have marked"
Rias was blushing, she was stunned and happy at the same time.
Everyone who saw it became frightened by what was happening on the television the demonesses hotly revealed. It was terrifying to erase someone from existence.
Shiro walked towards Rias. He saw Lust in Rias's eyes and even the ORC (Except Kiba) and the student council(Except Saji) were panting and leaking with lust. Shiro knew what had happened he had directed his Incubus aura towards all the women in this room and also because demons were creatures that were attracted by power they became very attracted to Shiro.
"Shiro?" Rias was confused by Shiro's change in nature but she didn't hate it instead she liked it.
Shiro didn't say anything and directly pressed his with Rias lips. Their kiss turned into a passionate kiss. A few minutes later they stopped because Rias was out of breath.
"Hah.... Hah.... I love you Shiro." Rias who was panting and confessed her love to Shiro.
"Yeah me too and I won't let you get away from me and whoever want you can only hope that he doesn't die trying."
Shiro snapped his fingers and then a throne that was beautiful and majestic was created. Shiro sat on the throne and made Rias and also Deisy who had been following him sit beside him. He crossed his legs while his hands were placed on Rias and Deisy's waist. He looked at everyone who was kneeling before him and also saw the women who were gasping for air and leaking fluids down their legs. He probably wouldn't do anything like this just, but after evolving he felt something holding him back and so he started to stop holding back and would do whatever he liked.
"Come here" Shiro said looking at the female student council members, ORC, Venelana, Grayfia, Serafall, Ravel, Sekvaira Agares, lady Phoenix, members of the Riser nobility. Hearing his orders the women then headed towards Shiro as if their instincts were telling them to submit to him and obey him. Sirzech, Zeoticus, and lord Phoenix were surprised to see their wives approaching another man. Seeing Shiro sitting on the throne and surrounded by women made everyone think. 'A true Demon Lord' Everyone thought when they saw his figure. And that's how Shiro was known as the true Demon Lord by the Devils even when he wasn't a Demon. And he also gained an hidden nickname that is Wife Thief because he stole the wife of the Demon King as well as other high-class devils.

A/N : Shiro wouldn't be so arrogant or always domineering he just got rid of his restraint. And this will be the only NTR in the story, he will also go to another world after 15 or 16 chapter. I also wanted to make a Lemon chapter with Deisy(Great Red) but some doesn't want it so I didn't.
