The possibilities are endless, he realized

He couldn't believe his luck. Somehow, he had the power to make any possession his by just writing his name. And apparently, it could even make the two most beautiful senpai’s showed their boobs to some lowly pervert like him(yes he was self-aware of his status, and he is proud of it!)

Now if his theory was correct(a rather simple one admittedly), this would change everything, and it might make one of his main dream come true.

“Why?” Sona asked, interrupting his thoughts. More confusion showed on her face “Is there a reason for this?” She asked with a slight frown, and at that moment Issei panics a bit.

“Think of it as making up for using my room without my permission,” He quickly makes up a reason “It’s my thing,” he added, his pervertedness is well known in the school so maybe that would work.

Sona understood and simply nod, extending her pale arm, though she looks away in embarrassment as she remembers her half-naked state.

This would be the moment of truth. He began to draw on her forearm carefully to make sure his name is written and not misspelled. He doesn’t want some nobody like Hyodo to have control of Sona.

“There,” Issei finished, his name is written on her left arm.

兵藤 一誠

Now for the testing,

“Sona Shitori,” Issei said with an attempt authoritarian voice.

“Yes Hyoudou Issei?” She responds. Though she had a feeling she isn't going like what might comes next.

“You’re mine right now right?” Issei tries to confirm. Sona looks at her arm with the ink mark and sigh, as if she has responsibility instilled into her that she would not enjoy doing in any capacity.

“It appears so, I am definitely your property right now,” Sona said, that word already made his cock twitch at the implication.

“And no one else?” Issei yet again confirms.

“No, I, Sona Sitri, is owned by you and you alone,” she stated.

Sitri? So Shitori is not her real last name? That’s interesting.

“Ok then, Rias, it’s your turn now?”

“Eh? Why me?” She asked,

“Well, you don’t want to leave Sona hanging right,” He said “Plus you both did have a conversation in my room without permission, so you are also liable.”

“Oh, ok then, that seems fair.” Rias states as she brings out her arms. Her gigantic breast somehow bounces from the small action as if the law of physics cannot stop to tell them to not move, God does he want to grope them.

He wrote his name as same as he did with Sona. Rias look at her arm and show an expression of realization and then **** acceptance.

“Now then, can you uh-place both of your arms behind,” Issei ordered, and they complied with his command, Sona blush as her blue bra and her almost non-existent curves is being inspected, though Rias couldn’t care less, merely want things to get over with. This makes his cock harder at how much control he has. They’re still in their skirts, so he opts to remove them showing those sexy panties

“I’m already at this stage, let’s not chicken out right now.” Issei thought, it’s time for the final, the dreams he wish as he had set foot on this school, ones that would make every man envy at him

“Take off your bras,” He yelled out in a grand tone. Sona flushed full scarlet, as she hesitated a bit, Rias seems to not care much, and follow his orders. Both remove their bras to reveal-

“OPPAI!!!”

Is the only thing in his mind, this is it, he has the luck to take a view of not only the mighty mammary that is Rias majestic boobs but also Student President admittedly adorable small ones, the ever stoic student council president, who is blushing red out of embarrassment just makes it cute and sexy.

The big melons of the red-haired princess, the small yet adorable perky of the student president nipples.

He takes a full-on view as he will cherish this memory in his mind forever.

Though as much as he would like to bang the two most popular girls in Kuoh right now(And does he want to), he is still in the dark about what is going on, and he only manages to outsmart them through pure luck.

And so, he asked them to reveal what they knew about this sacred gear thing and anything relevant, and they spill the beans.

And boy, did he get more than he bargains for.

Relics gifted by the gods, supernatural powers, Mythological beings, they told him the major stuff.

Devils and Angels are real, and the two in front of him are Devils who technically own the school.

They show their wings to him and the magic as both let out energy balls of their respective element to show proof.

It took a few minutes for him to process that info.

All myths are true, Devils and Gods exist. Sacred Gear are the gift of God for humans to defend themselves, and they want to recruit him in their 'peerage'.

This is honestly too much in his opinion,

“Wait, does that mean monster girls are real?!” Issei shouted before going into a major crisis. Yup, that would be the first thing on his mind when he discovers the existence of the supernatural.

Elves, Mermaids, and Catgirls, if devils can exist then those monster girls can too right?

“Yes, most of them are real,” Rias stated, wings slightly flapping to emphasize their statement. Issei’s thought run wild.

This is truly the greatest moment of his life, females with all fetish in a secret world he does not know about, with the power of his Sacred Gear, he could achieve his life long dream.

He could become the Harem King!!
