There are countless things Issei despised and one being the outer gods while the other is making him choose between his lovers. He had encountered this fighting then dark Apostles and outer gods that made him considered the two as one.
It could be considered taboo if mention around Issei even the persona foe or friends his anger would not easily subside. He loathes such a phrase to his very core. Even after countless years of slaughtering and wondering numerous worlds didn't dull his emotion when it comes to his loved ones.
His gaze locks into the head goddess of the Shinto faction as if she's nothing more than a mere ignorant child. Issei had leaked his horrifying aura that he kept tame surrounding himself of [Nihility] causing it to be hidden by anyone resulting to his power to be like a normal person.
Additionally, he had five hundred layered seal to help him minimize his power that once he reseal himself then his power would have explosive growth. For example, his based is high God class then use seal back to low then train toll reaching high again while still having the seal then the result is obvious.
For Issei to remove the fifth seal due to his rising anger could already show how hated the question is. Amaterasu hid her quivering body from his deathly stares.
"F-Forgive me it seems had said something inappropriate, Issei-done"
With that, the pressure was lifted as Issei's eyes return to a more relax and laid-back state. Yasaka who remain silent couldn't decide if she could be glad that Issei is willing to go as far as disregarding the world or be terrified that he only trying to unite the world just because it was the place where he lives.
"Ara~ I told you my husband is the best."
"No, I should be apologizing for acting harshly. Let's change the topic cause its becoming to tense."
Issei was a bit embarrass for lashing out to Yasaka best friend but doesn't mean he regretted it. He would do everything to save his lover even it cause his life. It was hypocritical for him since it cause his lover to disagree but doesn't care as long they live and happy. He already lived far too long and only living due to repaying past regrets.
Amaterasu was relieve that he didn't take it personal and was stunned seeing his gaze looking at Yasaka for split second. She understood where he was getting his faith from and amaze such terrifying ability.
'I see your faith for your lover is endless same goes for them . A bright future huh? I guess seeing where your divine light shine lead would surely be a paradise.'
"You are a rare man, Issei hyoudou. I won't tell you to protect Yasaka with your life because I already the answers."
"Hahaha thank you, Kami-sama."
"Just call me Amaterasu, Issei-dono."
"Ah? Well if that's the case just call me by my name, Issei or Ise."
She said giving a welcoming smile much to Issei surprised then did the same gestured. Ametarasu from their short chat had given her a good impression of him while Yasaka teasingly smiled.
Unbeknownst to any of them, She was already struck by Issei charm that lead to something more but that will be far in the future.
Another hour passed by and Amaterasu said her farewells to them as she needed to return and prepare for the upcoming battle that would soon come. Issei took out a small gem to Ametarasu much to her surprised.
"What is this, Ise?"
"It's contains a powerful burst energy that erased everything within thirty meter radius. Do note this only used when you are trap or surrounded with no ally as its dangerous as it can't separate friend or foe."
The small gem contains [Nihility] though it was still unstable of not being able friend and foe. Never the less, it is powerful artifact that could be used as trump card. Thankfully, it doesn't erased the one activating the gem.
Amaterasu scanned the small gem and could feel almost nothing of it even the slightest existence could be felt from the gem unless touch or observe carefully. She guess that Issei had the ability erased anything considering he was doing the same with his whole body.
"Amazing, I would surely used when the time comes. Thank you, Ise."
"Its no problem since your important to me."
Issei unconsciously said 'Me' instead of 'Us' quickly realize his mistake and tried to fix it but he saw Amaterasu slight blush. Yasaka teasingly smiled at Issei who went pale from his mistake.
"Wait I mean Us!! I'm just gotten used to saying Me when around beautiful woman."
"Ara~ Anata are you flirting with Amaterasu?"
"Ah no no!? Of course not. Though I'm not lying you're an important person."
"Fufufu no it was not problem at all. In fact I thought its quite charming the way you said it. Well anyway I'll take my leave."
Amaterasu burst into flame then disappeared from their home leaving Yasaka giggling at Issei dismay. He wrapped around his arm to her shouldered and whispered.
"Just you wait then you won't walking for days."
Issei left the stunned Yasaka laughing as she paled knowing how his a monster if he wanted to do. Having a dragon and infinite had its charm.
_______________________________
Few days had passed since Amaterasu had visited, Issei had busily been investigating of the Khaos Brigade. He had place another automata spy on where Trihexa was and hadn't found anyone trying to break it.
The old devil faction hideout was still a mystery and guess it's place in sub dimension where he can't find it. This only confirm his suspicion of a Dark apostle into contact with them. Another thing he found out was Irina and Xenovia would soon arrive in Kuoh told Diablo to bring them to him. As for Hades and his Alliances of hell, none had into contact with another.
Issei had create over dozen Automata allowing him to send a few of them to recruit subordinate such as Crom Cruach who hasn't met with Rizevem. He can easily invited him with the pretext of fighting something powerful.
He planned to revive Apophis and Azi dahaka as they can provide support in a fight. Furthermore, they are easy to tamed as long entertain with strong opponent. Though Issei would place seal in order for them to not betray him.
"So you're the one this things boss huh? I'm little bit interested in your offer."
Issei stood in front of a tall handsome man wearing a black coat with a long mixture of black and blond hairs as well as heterochromatic eyes where his right eye is gold and his left eye is black and he has pointed ears. At first glances his laid back posture indicate he was arrogant but a warrior could clearly see his power.
This person is Crom Gruach a person who had the power to surpass the heavenly dragon (prior meeting issei) capable of fighting him toe to toe with Vali old Diabolos Dragon God form.
"If you wish we can have little spar to show that I can offer a strong opponent in exchange for your cooperation?"
"You got yourself a deal since it's been boring trying to find a strong opponent lately."
Crom Gruach had reach limit in who can match his power even tried finding Ophis and Great red but the two had long since joined Issei. He was surprised when an Automata showed itself to him inviting him to meet Issei. This raises his interest leading him to accept and arriving in another dimension where Issei waited for him.
"Alright, let's….begin!"
Crom Gruach didn't hesitate once Issei spoke throwing a powerful punch blowing away the nearby land. He then coated his other fist with a thick dragon aura punching Issei straight to the face creating hurricane from sheer force. However, as the dust cleared Issei stood unharmed with Crom Gruach not even touching Issei.
"Interesting power you got there. I thought you would all talk."
"Thank you however it still far from perfect. Now then it's my turn."
The evil dragon didn't even know what hit him being sent through the mountain range creating a massive crater from the last mountain. He stood up smearing the dirt on face grinning.
"Hahaha, damn is that a good punch! Finally someone capable of making go all out!"
