Seeing the girl understood nothing—Kenshin placed a hand on her head and whispered: "Relax and watch."
Then the girl saw several small scenes. In one scene—a man in a coat silently approached another man sitting at a cafe table, pulled some incomprehensible thing from his inner pocket—aimed at the other man's head, and a loud explosion sounded. The sitting man's brains were blown out—and he limply fell face-first into a plate of soup.
In the next scene she saw a beautiful graceful girl similar to herself lying on the edge of a very tall building's roof. Kasumi subconsciously marveled at such beauty—seeing out of the corner of her eye a huge number of similar buildings. In front of the girl lying on the roof edge was a huge long iron thing completely incomprehensible to the black-haired kunoichi. Suddenly a not very loud pop sounded—and time before Kasumi's eyes seemed to slow down, her consciousness involuntarily flew very far and stopped about a kilometer away to see an elderly man exiting a car have half his head torn off.
"So far?!" she exclaimed surprised in her subconscious—but the scene changed again, and Kasumi found herself high in the sky above a city large by her standards. For several dozen seconds she enjoyed incredible views until finally noticing a strange-looking bird quickly approaching her. When the "bird" got even closer—Kasumi widened her eyes in surprise—unable to believe what she saw. This bird was completely metal—size of a small one-story house.
Suddenly a quite large metal "egg" fell out of the "bird" and flew down—and the bird itself increased speed and got away as quickly as possible. Kasumi involuntarily smiled at this ridiculous sight. The metal bird did its bird business and sent the same metal "gift" to someone's heads. But suddenly Kasumi's smile froze.
At the landing site of the bird egg—a powerful explosion occurred, and surrounding houses were simply blown away. The blast wave spread further and further—demolishing more and more houses—turning people there to ash. At the explosion site appeared a huge mushroom-shaped smoke cloud—and it grew larger and larger, and the shock wave demolished buildings further and further.
"Aaaaah!" Kasumi exclaimed and breathed heavily. Her entire face was red and sweaty—she saw something so powerful for the first time. Even the tailed beast bomb the great grandfather saw wasn't so destructive according to stories. She had no idea what could stop such power.
"W-what was that?" the girl asked—gasping.
"In the first scene—a self-loading pistol. In the second—a large-caliber sniper rifle. In the third—the atomic bomb 'Little Boy.' Not the most powerful existing in my world."
"N-not the most powerful?! Uuuugh—god—what horror… You say all this is made without chakra or other strange energy?" she asked—to finally make sure.
"Yes—and all this can be made in your world, but it requires very serious education—a bunch of research, a huge production chain, and many involved people. Your world for some reason develops very slowly. Most likely it's all because of chakra—and all efforts go into mastering it, while simple and "useless" technologies that will become incredibly useful only after fifty years of systematic research—are unnecessary."
"And how many people died in that city?" the girl asked—holding her breath.
"About one hundred fifty thousand." Kenshin answered—and saw Kasumi's eyes widen again.
"Lord… That's almost the entire population of Konoha… And is there no way to defend against this bomb?"
"There is. Need to have the same or even more powerful—and means of delivery. Thanks to this such weapons are no longer used in wars in my world."
After this Kasumi again laid her head on Kenshin's chest and thought deeply. She couldn't imagine such incredible weapons existed. She was still interested in the principle of operation—but now wasn't in the mood to ask her husband anything else.
After ten minutes the girl fell asleep. Kenshin only stroked her smooth back and pecked her crown—and after some time fell asleep himself.
*****
Waking early in the morning—Kenshin didn't find Kasumi nearby. Shrugging—he went to the toilet to relieve himself and saw her in the shower stall standing under streams of warm water.
"Good morning—girl." Kenshin said and—without the slightest embarrassment—began relieving himself.
"Good mo… God—you're such a pervert! How can you do this in front of a decent girl?!" Kasumi said with laughter—not taking her eyes off this action.
"Good that you're a pervert too. A decent girl wouldn't watch such things." he said with a sly smile then quickly pulled off his boxers and walked toward the girl.
"Ah—don't come near—pervert!" Kasumi squealed pretendingly and pressed against the wall. She had nowhere to run—so several seconds later she was in the embraces of her loving man.
After several minutes Kasumi could only scream loudly—pressed with her breasts against the transparent glass of the stall. It was her first time in such a position—but she liked it. Before orgasm the girl forgot how to breathe—and when she came—her legs gave way, and she almost fell but was lovingly caught by Kenshin's strong hands—who didn't stop driving his large cock into the young girl's tight small pussy with all his might.

"Wow! Truly a flower grown in the Nara Clan…" Kenshin thought then suddenly asked.
"Wait—is Kage Mane no Jutsu a Kekkei Genkai?" he asked surprised the black-haired beauty.
"Um—not quite. Even in our clan they don't fully understand why it happened, but shadow control ability is about eighty percent something like Kekkei Genkai and is inherited, but anyone without Nara Clan blood in their veins can also learn it. Only in that case training will be incredibly difficult. One such person was the First Hokage Senju Hashirama. And another—the Third Hokage, Sarutobi Hiruzen."
"Even in your clan archives there's no information about this?" Kenshin asked in surprise. Until now he was certain Nara Clan techniques could be taught to anyone.
"I don't know… Perhaps this information is secret and 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—because at the time outsiders called him "Shadow," and our clan members—"Great Ancestor." It's only known he appeared suddenly and shook the then-territory of the Land of Fire. He was like you—mysterious and enigmatic…"
"Well—that's something… I couldn't imagine your clan history was so mysterious… Good—let's have breakfast then continue." Kenshin said and stroked the girl's head. She purred tenderly and nodded gently—heading after him.
