Itachi Uchiha in High School DxD

The next Day.

"Finally, we have done it, bro, What do you think?" Issei glanced furtively at the girls in the distance, his eyes almost filled with a particular intention as they briefly shifted toward Itachi to his right.

"Well, I must say I never saw someone like this..." Itachi shook his head with resignation, "Actually, I saw much more than this during my two lives, so it's not like I feel surprised or anything..." He simply sighed, looking at his friend like a man looks at a child.

However, Issei quickly looked back down, observing an almost inhuman amount of exposed skin.

Both were standing on top of the fake ceiling of the girls' bathroom at Kuoh Academy. A few days had passed since Itachi promised to train Issei, and although he was creating a training plan for him, he still decided to keep the promise he made to his friend after that Genjutsu.

Issei looked like a hungry beast; his almost dilated eyes focused on every movement of the beautiful girls in the bathroom, watching them with a particular desire that sparked curiosity in Itachi's heart.

"Can women provoke such desire in a man?" Itachi wondered, perhaps because of his former life as a ninja full of discipline, or because in the world he came from discipline was instilled from youth.

But Itachi swore that even Jiraiya, the old pervert, would fall short compared to Issei; he had never seen such a reaction in a man upon seeing a naked woman, so he simply continued observing his friend.

Issei's expression was of absolute desire; Itachi even thought the nails on his fingers grew like a predator's claws, the hairs on his skin stood up, while his overall appearance was nothing less than that of a wolf about to die of hunger seeing a feast.

Itachi really didn't understand it; he watched, almost captivated by seeing a strange creature. For him, a ninja, a woman was just that.

A prettier face? A more voluptuous body? A younger girl?

In reality, Itachi was right: in the end, the skin of a fat woman is just skin like the skin of a supermodel; the reproductive system of an unattractive woman is just as much a reproductive system as that of a supermodel. In the end, both are humans.

However, one triggers a fervent desire in men, and the other, well, generates rejection. Itachi thought this is due to men's evolutionary traits prioritizing wide hips for good childbirth, large breasts for baby survival, and a pretty face as a marker of better genetics to pass on to the next generation.

Still, Issei's desire when seeing beautiful naked girls exceeded Itachi's expectations.

"Why is it not the same to touch an ugly girl as a pretty girl? Both are made of the same thing, skin, bones, cells, so, Why does a pretty girl excite you so much?" Itachi asked, although he knew the answer, he wanted to hear it from his good friend's mouth.

However, Issei ignored him; he remained absorbed, with a lost gaze, a pounding heart, and a busy brain. Itachi even thought he saw something hard pressing against Issei's pants from the inside.

Time passed, and when the girls finally left the bathroom, Issei regained his usual calm. He breathed heavily and took a deep breath before calming down.

"Well, bro, it's actually hard to explain. I mean, I had never really thought about it," Issei said, surprised by Itachi's question.

Why does his body react differently to a pretty girl than to an ugly girl if both are made of the same essence?

It's a stupid question, really, but Issei had never considered it, and the more he thought about it, the more stupid it seemed.

"Isn't it obvious, bro? It's because pretty girls are pretty girls, and an ugly girl is, well, an ugly girl..." Issei's answer made Itachi shake his head.

"In my old world, you wouldn't have survived even a couple of days, I guess..." Itachi smiled before putting a hand on Issei's head and starting to ruffle his hair.

The poor boy seemed insulted; he quickly turned to look at Itachi with an angry face, about to push Itachi's hand and start a fight, but his body did not obey him.

"Sharingan..." Issei murmured; he had learned that Itachi's eyes, Sharingan, granted such ability, so he could only watch, unable to move, as Itachi ruffled his hair.

"However, it's fine. I mean, I wouldn't want you to become insensitive to girls, hahaha," Itachi smiled, perhaps recalling the face of his little brother who was always a fuckboy unconsciously.

"Bro, why don't you get excited when you see beautiful naked girls?" Issei asked, curious; his almost shining eyes looked at Itachi and showed genuine curiosity inside him.

Itachi thought for a moment; he really thought about it, brought a hand to his head, and squinted his eyes; he really didn't know the reason, maybe, first of all, it was because of his ninja training focused on discipline.

"Maybe it's because I have a lot of girls available, I mean, if I say something, they'll come to me," Itachi said, smiling, remembering what he once read in a book on the subway, "When you have something in abundance, that something stops being valuable," he repeated the same words written in that book.

His little and foolish friend nodded several times, trying to understand the wisdom in those simple words. "Don't you understand? Since you don't have any beautiful girls, you think they are worth more than you, so you put them on a pedestal," Itachi smiles, "But if you had many beautiful girls, they would be the ones putting you on a pedestal."

Time passed quickly, and soon classes started again in the afternoon.

Itachi, as always, said goodbye to Issei before returning to his classroom. He was ready to sit in a corner, contemplate the forest through the window, and simply wait for class to end when someone suddenly blocked his way.

"Itachi, it's a pleasure to see you again," Itachi turned to the girl who suddenly approached him. She had long straight black hair, an elegant figure, glasses matching her pretty face, white and smooth skin, and a gentle appearance resembling a secretary.

"Miss Tsubaki," Itachi smiled, closed his eyes for a moment before showing a slight smile, "What do you need from me?" he said, after all, although this girl, Tsubaki Shinra, was part of his class, they don't talk much.

"Well, actually, I would like to know if you would like..." she blushed slightly; her eyes wandered from Itachi's perfect face to his body, "t-to go out with me?" she finally asked, lowering her head slightly.

"..."

Itachi remained silent, observing the delicate and beautiful girl standing in front of him for a moment before saying, "No," and simply taking a seat in a corner.

Tsubaki Shinra's heart took a blow; her body was flooded with an unpleasant electricity while her mind collapsed.

However, Itachi really stayed thinking for a moment, "It's because I have too many options," Itachi smiled thinking about his earlier words.

"It's better if I train Issei as soon as possible to avoid some problems," Itachi thought; after all, after learning about the existence of the supernatural, he really viewed this world from another perspective.

He watched Tsubaki Shinra, not far away, walk depressed to a desk, and his clear eyes quickly caught the strangeness in this girl, "She should be someone supernatural," he murmured in his mind.
