Seeing that the girl didn't understand, Kenshin placed a hand on her head and whispered, "Relax and watch."
Then the girl saw several short scenes. In one, a man in a coat silently approached another man sitting at a cafe table, pulled something incomprehensible from his inner pocket, aimed it at the other man's head, and there was a loud bang. The man at the table had his brains blown out and slumped face-first into his soup bowl.
In the next scene, she saw a beautiful, graceful girl resembling herself lying on the edge of a very tall building. Kasumi subconsciously marveled at such beauty, catching sight peripherally of a huge number of similar buildings. In front of the girl on the roof's edge was a huge long iron thing, completely incomprehensible to the black-haired kunoichi. Suddenly there was a not-very-loud pop, and time before Kasumi's eyes seemed to slow; her consciousness unwillingly flew very far and stopped about a kilometer away to see half a head torn off an elderly man stepping out of a car.
"So far?!" she exclaimed in surprise in her subconscious, but the scene changed again, and Kasumi found herself high in the sky over a city large by her standards. For several dozen seconds, she enjoyed the incredible views until she noticed a strange bird rapidly approaching. When the "bird" got closer, Kasumi's eyes widened in shock, unable to believe what she saw. The bird was entirely metal, the size of a small one-story house.
Suddenly, a fairly large metal "egg" dropped from the "bird," falling downward, while the bird accelerated and fled as fast as possible. Kasumi involuntarily smiled at the absurd sight. The metal bird had done its business and sent a metal "gift" onto someone's heads. But suddenly Kasumi's smile froze.
At the landing site of the bird's egg, there was a massive explosion, and the surrounding houses were simply blown away. The shock wave spread farther and farther, demolishing more and more houses, turning people there to ash. A huge mushroom cloud of smoke appeared at the blast site, growing larger and larger, while the shock wave knocked down buildings farther and farther.
"Aaaah!" Kasumi exclaimed, breathing heavily. Her whole face was red and sweaty; she had never seen anything so powerful. Even the Tailed Beast Bomb that her great-grandfather had seen wasn't that destructive, by his accounts. She had no idea what could stop such power.
"Wh-what was that?" the girl asked, gasping.
"In the first scene—a semi-automatic pistol. In the second—a large-caliber sniper rifle. In the third—the 'Little Boy' atomic bomb. Not the most powerful in my world."
"N-not the most powerful?! Oooh, God, what horror... You mean all this was made without chakra or other strange energy?" she asked, to confirm once and for all.
"Yes, and all this could be made in your world, but it requires very serious education, tons of research, a huge production chain, and many involved people. Your world develops very slowly for some reason. Probably because of chakra—all efforts go into mastering it, and simple 'useless' technologies that become incredibly useful only after fifty years of systematic research aren't needed."
"And how many people died in that city?" the girl asked, holding her breath.
"About one hundred fifty thousand," Kenshin answered, seeing Kasumi's eyes widen again.
"Lord... That's almost all of Konoha's population... Isn't there a way to defend against that bomb?"
"There is. You need one just like it, or even more powerful, plus delivery means. Thanks to that, such weapons aren't used in wars in my world anymore."
After that, Kasumi laid her head back on Kenshin's chest and fell deep into thought. She couldn't even imagine such incredible weapons existed. She was still curious about how they worked, but now wasn't in the mood to ask Kenshin about anything else.
Ten minutes later, the girl fell asleep. Kenshin just stroked her smooth back, kissed her forehead, and soon fell asleep himself.
Waking up early in the morning, Kenshin didn't find Kasumi beside him. Shrugging, he headed to the bathroom to relieve himself and saw her in the shower stall, standing under streams of warm water.
"Good morning, girl," Kenshin said, unashamedly relieving himself.
"Good... God, you're such a pervert! Is it okay to do that in front of a decent girl?!" Kasumi said with a laugh, not taking her eyes off the action.
"Good thing you're a pervert too. A decent girl wouldn't watch," he said with a sly grin, then quickly pulled off his boxers and strode toward the girl.
"Ah, don't come closer, pervert!" Kasumi squealed pretentiously and pressed against the wall. With nowhere to run, a few seconds later she was in the arms of the loving man.
A few minutes later, Kasumi could only scream loudly, her breasts pressed against the transparent glass of the stall. It was her first time in this position, but she liked it. Before orgasm, the girl forgot to breathe, and when she came—her legs buckled, and she nearly fell, but was lovingly caught by Kenshin's strong arms, who didn't stop thrusting his big cock with all his might into the tight little pussy of the young girl.
After the shower, Kenshin switched to work mode and first decided to check the girl's stats.

"Wow! Truly, a flower grown in the Nara Clan..." Kenshin thought, then suddenly asked.
"Wait, isn't Shadow Imitation Jutsu a Kekkei Genkai?" he asked the black-haired beauty in surprise.
"Um, not quite. Even in our clan, they don't fully understand why it happened that way, but the shadow manipulation ability is about eighty percent like a Kekkei Genkai and hereditary, but someone without Nara Clan blood in their veins can also learn it. Just extremely difficult. One such person was the First Hokage, Hashirama Senju. And another—the Third Hokage, Sarutobi Hiruzen."
"Not even in your clan archives?" Kenshin asked in surprise. Until now, he'd been sure Nara Clan techniques could be taught to anyone.
"I don't know... Maybe that info is secret, known only to the great elder and clan head. All I know is our clan ability originated from the founder. No one knows his name; outsiders called him 'Shadow,' and clan members 'Great Ancestor.' It's only known he appeared suddenly and shook the Land of Fire's territory back then. He was like you—mysterious and enigmatic..."
"Wow... I never imagined your clan's history was so mysterious... Alright, let's go have breakfast, then we'll continue. – Kenshin said, stroking the girl's head. She purred affectionately and nodded gently, following after him."
