Fast forward a few days and it was now Saturday. The scheduled date between Issei Hyoudou and Amano Yuuma, his future murdered.
Giyu looked at himself in the mirror as he was currently in a transformation jutsu. He looked plain and average, with a normal mediocre face and normal black hair.
Nodding to himself he also cast an easy low level spell that would make others lose focus on him causing others not to pay attention to him. This way he could tail the two without being too suspicious.
---
As Giyu followed them around like a creep he couldn't help but look at how stiff and awkward Issei was.
'I forgot how Japanese protagonists were' Giyu thought to himself as he saw how much of a shy beta Issei was. He wondered where all his energy was from before. One second he was screaming he was finally going to lose his virginity and the next day he acted so awkward and shy.
'Well, I guess this is his first date' Giyu thought to himself.
...
'Hm, He's just staring at her breasts not even bothering to hide it. I will give her props for holding back and not outright just killing him' Giyu thought looking at the two in the cafe.
He followed them for another few hours before the sun was finally setting and the duo that was on the date reached the fountain.
Giyu was now looking from afar as he brought out some popcorn from his pocket dimension. 'It's about to start.' He thought as he silently ate.
"Would you die for me?" Giyu heard Raynare say through his super hearing.
The next second she transformed into her fallen angel from as she wore clothing that barely hid her privates. As she transformed he caught sight of Issei drooling. 'Ah this is the part where he got excited seeing bare breasts for the first time' He thought as he remembered the first episode of the anime.
The next second he saw Raynare impale Issei with a light spear before she told him to blame God for giving him a sacred gear.
Looking at the dying boy, people would think that he would be regretting how he would leave his family and friends but Giyu knew the boy in front of him was cursing that he didn't get to fondle Raynare's tits before he died.
He waited for a few more minutes before he saw a magic circle with the crest of Gremory appear. Soon the little sister of the current Devil King Lucifer popped out. He watched as she tried to revive him with a pawn.
But as expected with someone with the Boosted Gear it didn't work, she then began adding more pawns before growing desperate after even 6 of her pawns didn't work. She tried adding the seventh pawn but to her despair it still didn't work until she of course added her eighth pawn.
She looked relieved and was probably excited about getting a servant worth 8 pawns. She soon cast a magic circle as She along with an unconscious Issei disappeared.
'Well, it's about damn time' Giyu thought vanishing in a swirl.
...
Waiting for Rias to leave he warped in Issei's room as he floated using the Deva path. He wouldn't dare to stand on the floor of the room, God forbid what if it was sticky?
He shivered at the thought before he floated in front of Issei's body and used the Human path's ability of extracting souls to separate the boosted gear from Issei's soul.
Soon a red glow emerged as a red gauntlet with a green orb appeared. He then used the human path to attach to boosted gear onto himself before he left to his pocket dimension.
...
Now in the Kamui dimension, Giyu sat in a meditative pose before he cleared his mind and focused his energy.
Soon a red gauntlet appeared in his hand while in his mindscape he was suddenly greeted with a large red western dragon.
*ROOAARR!!*
"YOU HYBRID! HOW DARE YOU TAKE ME FROM MY HOST!" The voice of the Red Dragon Emperor, Draig sounded off.
"Hn, calm down. Let us have a civilized conversation" Giyu said not minding the dragon. After all he wasn't afraid of Draig.
"GRRR! YOU PUNY HYBRID-" Draig said before he was cut off by Giyu.
"As I said, calm down. And why do you keep calling me hybrid?" Giyu said as he narrowed his eyes.
"DON'T MOCK ME HYBRID! I KNOW WHEN ONE IS OF 2 DIFFERENT RACES WHEN I SEE ONE. HUMAN YOUKAI HYBRID!" The Red Dragon yelled before it began speaking again "NOW TELL ME YOUR REASONING FOR SEPERATING ME FROM MY HOST!"
"Heh, you really want to know?" Giyu said as he chuckled slightly before he activated his Mangekyo Sharingan. "Very Well then, I'll have to show it to you. Though you would probably regret it later, you asked for it!"
'Sharingan: Genjutsu!' Giyu internally said as he locked eyes with the Dragon.
He had used a genjutsu to show Draig his future with his host. Now his whole future because Issei would eventually become one of the Strongest Red Dragon Emperors, but just the part of showing how pathetically weak and perverted his host was and his future title as the Oppai Dragon Emperor.
For a Dragon who earned his title and infamy through many battles, the fact that it was tarnished in such a manner, would be aggravating. This would definitely anger Draig, especially of how prideful Dragons were.
*ROARR!!!*
"THAT DAMNABLE HUMAN!!! HOW DARE HE!!!" The welsh dragon raged.
"Do you see now? I merely saved you from becoming a laughing stock. I have the ability of minor foresight, I had suddenly gotten that vision of the future of your host. I felt bad for you, since a mighty dragon feared by all would be reduced to such a state. Besides I have a preposition for you Draig." Giyu said with a smile. He had knowledge of future events, so he could just lie and say such things like he could see the future. I mean Gods, Devils, and other races exist. Anything is possible in the supernatural, surely there has to be someone with foresight.
Calming down from Giyu's explanation Draig said " Very well young hybrid, I guess I can thank you for this. Now tell me of this preposition of yours, do you want to be my wielder? Though I can sense you already far surpass my power even in my prime"
"Close but not quite. What would you say to being my partner, my contracted familiar? I might have a way to restore your body in the future, are you in?" Giyu asked.' I just want a pet dragon is all' He thought to himself.
"Oh being a familiar? This is the first time since I have been born to have ever been asked to be one, HAHAHAHA! Interesting, normally I, no even other Dragons would reject, but since you are much stronger than I am. I am willing!" Draig said.
"Excellent" Giyu said.
