Becoming Enkidu in DxD-Chapter 300: Teaching Busujima Saeko!

Chapter 68 — Teaching Busujima Saeko!

The relentless barrage of questions left Hikigaya Hachiman speechless. His mind froze, tangled in doubt.

’Wait... could it be that I actually like Totsuka Saika—a beautiful boy who looks like a girl?’

He didn’t know. Or maybe he did—he just didn’t want to admit it.

After all, this was Japan. In a society like this, a relationship between two men would be easily misunderstood.

And for the current Hachiman, he didn’t yet have the courage to face something that huge.

"I..."

Just as he was about to explain himself, Hachiman realized that Yukinoshita Akira had already vanished.

All the words he had prepared were swallowed back into his chest.

But in the end, a person might be able to lie to the whole world—just not to themselves.

"Don’t you think you went too far?" Yukinoshita Yukino asked sharply, her tone filled with disbelief as she watched Hachiman, clearly still dazed by Akira’s teasing.

To push—no, to force—a man toward another man... was that even human?

"What are you talking about? I just helped their love bloom," Akira replied smoothly, his lips curving into a mischievous grin. "They’re destined partners."

"You expect me to believe that?" Yukino shot him a glare. Two boys destined for each other? What kind of absurd joke was that?

But before she could retort further, her voice faltered.

Because what she saw before her eyes... was a sight painful enough to burn.

A boy prettier and softer than most girls—his cheeks faintly red, his expression shy—was speaking to another boy, head slightly lowered.

No one could hear what they were saying, but their body language alone screamed couple.

Even worse, it wasn’t just Saika’s face that was blushing—Hachiman, the dead-eyed loner himself, was also turning red.

It was like watching a meteor crash into the earth. Hachiman—that Hachiman—actually blushing? Surely, the end of the world was near.

Watching them from a distance, Yukinoshita Akira made up his mind.

The five primary Breathing Styles—Water, Thunder, Stone, Flame, and Wind—each needed worthy successors. Four already had theirs.

And now, he had finally found the perfect candidate for the last one.

Yes—Hikigaya Hachiman.

As the "true protagonist" of this world, Hachiman’s growth would surely be remarkable if he mastered a Breathing Technique.

And now, with demons appearing in this modern world, perhaps it wasn’t an exaggeration to call him the destined savior.

Of course, that wasn’t Akira’s only reason.

A flicker of guilt lingered in his chest.

In the original story, Hachiman and Yukino—after all the pain and confusion of their youth—eventually became a couple.

When the third season of Oregairu ended, Akira himself had felt as though his own youth had ended with it.

Naruto had become Hokage. Kurosaki Ichigo had saved the world. Only Luffy was left chasing the Pirate King’s throne.

But now, because of his presence in this world, that destined ending between Hachiman and Yukino would never come to pass. Even Yui would lose her chance.

If that was the case, then perhaps giving Hachiman something else—a small gift—could serve as redemption.

Time passed quickly. The club activities ended, and everyone headed home.

But this time, Busujima Saeko accompanied Yukinoshita Akira and Yukinoshita Yukino back to Akira’s apartment.

"Alright," Akira said, setting his Nichirin Blade down beside him. "The Breathing Style I’ll be teaching you is called Thunder Breathing. Among all techniques, it’s the fastest and most explosive."

"The fastest and most explosive..."

Saeko’s eyes shone with enthusiasm. It was clear she liked the sound of that.

After all, the Busujima family had long been known for their swordsmanship style—one built on offense and overwhelming power. Thunder Breathing suited her perfectly.

"The Breathing Technique I’m referring to..." Akira began explaining, just as he had when he’d taught Yukinoshita Yukino before.

However, there was one major difference this time.

Yukino had started from absolute zero, while Saeko already possessed a strong kendo foundation.

As expected, within just a few hours, Busujima Saeko had fully grasped the basics of Thunder Breathing.

The speed of her progress stunned Yukino, who had needed two full days under Akira’s supervision to even understand the fundamentals.

In fact, even today, she had only barely managed to enter the early stage—thanks to the pressure of their match.

Compared to Saeko, she couldn’t help but feel utterly outclassed.

A soft breath escaped Saeko’s lips as she steadied her breathing.

"So this is Thunder Breathing... It feels amazing. With this power, I might even be able to surpass my father," she said, her tone brimming with excitement, a faint blush coloring her cheeks.

Her father wasn’t an ordinary man—he was one of Japan’s strongest swordsmen.

Until now, she had only ever admired him from behind, chasing his shadow. But now... for the first time, she felt as though she might have surpassed him.

"You’ve only just begun," Akira said calmly. "There’s still much to learn. Techniques that combine swordsmanship and Thunder Breathing... full synchronization of your breathing and blade... even Total Concentration Breathing and the Transparent World—you’re still far from mastering them."

"Eh? There’s still that much more?"

"Of course. Thunder Breathing is only the beginning. You can think of it like learning how to hold a sword in kendo. The path ahead is long."

And just like that, Saeko’s blazing excitement fizzled into quiet despair.

Time flowed onward.

A week passed since that day.

Yukinoshita Akira spent his days in quiet routine—school, home, training, and teaching both Yukinoshita Yukino and Busujima Saeko.

When weekends came, he left Chiba City to hunt demons in other regions, raising his inheritance rate through real combat.

Then one day, a familiar sound echoed in his mind.
