Crossover Anime: From DanMachi to Becoming a Garbage Scavenging Master

The place of exile for the Void Blade School is not the island of Bu Cheng.

For the past month, that door has opened every morning in the sea breeze.

Zheng Tianxing would always emerge from the doorway to bring the two girls to practice, along with some novel foods. He would chat with the woman on the reef about the outside world and tell her about her brother's travels. He would then pick the girls up as night fell. He maintained a perfect distance, like an old friend.

This once desolate island has gradually become more lively.

Nagisa sat on the rocks, her gaze fixed on the twins practicing in the distance, letting the sea breeze tousle her long, dark green hair.

The elder sister, Alfia, attacks with the ferocity of a raging fire, her fists and feet always finding openings and striking directly at vital points. The younger sister, Metria, is the complete opposite—her offense is unassuming, but her defense is effortlessly natural. Deflecting force and blocking seem like innate instincts; every defensive maneuver is fluid and graceful. One attacks swiftly, the other defends steadily, honing their skills in each exchange.

Besides their talent, the two also have completely different interests. In her spare time, Alphia likes to continue honing her skills. Metalia, on the other hand, is less concerned with strength and more curious about the history of the Hollow Blade School. Nanami spends more time talking to her sister, occasionally telling her interesting stories about their ancestors. Whenever this happens, Metalia always listens quietly, her eyes focused.

Just then, a pill was handed to Qi Shi.

Nanami reached out and took it, and after swallowing it, a warm sensation slowly spread through her body. Her recently heavy body seemed to have returned to a healthy state. She knew very well that this ailment could not be cured by medicine—but once you've experienced health, falling back into illness is a more cruel contrast than never having had it at all.

"Yesterday," Tenko suddenly spoke, "Nichika encountered the wielder of the blunt sword, Uren Ginkaku, the lord of Shimoku Castle in Inaba Province."

Nanami looked up at him.

"That guy has a famous sword-drawing technique called 'Zero Flash,' which is said to reach the speed of light." He smiled. "But I went to check it out yesterday—it's not even close to the speed of light, let alone a sonic boom. It's barely close to the speed of sound at most."

He looked at Nanami: "Guess how Nanami won in the end?"

Nanami barely hesitated before asking, "...Seven's Style: Du Ruo?"

Tianxing smiled: "As expected of a master of the Void Blade Style. Since she couldn't outrun Zero Flash in a direct speed fight, Seven Flowers used Du Ruo's footwork to confuse the opponent, then stomped hard on Touji's face, who was standing directly behind her, and used the momentum to leap to the opponent's blind spot—the ceiling directly above—and finally finished with the ultimate technique 'Falling Flowers in Disarray,' slashing down with her foot."

Nanami paused for a moment, then sighed softly, "...This is really reckless, Nana."

-----------------

The sea breeze swept over the rocks, carrying a faint salty taste.

Tianxing watched the two figures sparring again in the distance, a sense of satisfaction rising in his heart. Over the past month, Alphia and Metalia had solidified their foundations—last night, when updating their Blessings, both of their stats increased by about two hundred points. At this rate, they would reach the S-rank 999 cap in another four or five months. However, considering the existence of the Flame, they should be able to break through the limits of the DanMachi world like Bell. In any case, reaching Lv.2 within the year was not difficult.

During that month, he returned to the world of Danmaku alone, explored the entire town of Melen, and became acquainted with most of the residents of the shopping district and the fishermen at sea. Occasionally, he would help those in need with healing pills and Jim Rogers bread-flavored soda, earning him the reputation of "Good-natured God" in everyone's eyes.

After completing two major transactions with the Nyod Familia and accumulating funds, he hired someone to build a large villa in the woods not far from the shopping street. By the time the villa was completed, Alphia and the others should be returning from the world of swordsmanship—moving into their new home would surely bring them some pleasant surprises.

Meanwhile, in the world of Katanagatari, after a month of companionship, the desire for life and the yearning for the outside world have quietly taken root in Nanami's heart. The spark has been ignited; all it needs is a gust of wind to set it ablaze.

In the destiny he had glimpsed, Yasuri Nanami would fight the three members of the Maniwa Ninja Insect Group three months later, after which her body would collapse and her life would begin its countdown. In order to find the meaning of her existence, she chose to go to sea to pave the way for her only brother who cared about her, thus embarking on a path that was almost self-destructive—disregarding life and death, slaughtering the Frozen Sky Clan, massacring the Sword-Go-Ken Temple, finding the evil sword, Am, and finally leading her brother to his own death.

And now, before anything has even begun, as long as hope is given amidst despair—a healthy body, a reason to exist—she can pull herself off that self-destructive path. And his kin will welcome a new member.

-----------------

Qi Shi sat down beside him, and after a moment of silence, suddenly spoke: "So—you said you had important business to discuss with me, are you finally going to tell me your true intentions for coming to this island?"

"Oh dear, am I being that obvious?"

Nanami said calmly, "The Kyoto style is not suitable as an entry point for swordsmanship, and your maids are quite talented. Under these circumstances, it seems a bit deliberate to send them here to practice."

Tianxing chuckled softly: "I do have other purposes, but what I said at the beginning about wanting you to be my kendo teacher was not false."

Nanami did not answer, but simply stared quietly at the distant sea.

After a while, Tianxing suddenly asked, "Qishi, tell me—why can birds fly?"

Nanami paused slightly, "Because you were born with wings?"

"But if the gods break their wings, will they still yearn for the sky?"

A sea breeze swept by.

Nanami paused for a moment, then said softly, "If I've ever flown, I probably would. Even if I can never fly again... I'd still yearn for the sky and all that..."

"It seems you already have the answer in your heart."

The next moment, the air suddenly became heavy.

The sea breeze ceased, the sound of the waves vanished, and the entire uninhabited island seemed to be paused—the divine power of the Dizan slowly emanated from Tianxing, and an invisible pressure spread in all directions. His voice also became ethereal and distant, as if it had fallen from beyond the world.

"This world is already broken, and all things will eventually come to an end. And you—Nanami Yasuri—your existence has exceeded the limits that this world can bear. Therefore, this world rejects you, it cannot contain you, so it can only weaken you, suppress you, and let your body continuously collapse from the moment you are born."

The sea surface shimmered with a golden light in the distance.

"And so, your wings were broken."

Nanami remained silent for a long time, then suddenly laughed—the laughter was soft, but carried a hint of almost mocking sorrow.

"Is this why I've been plagued by illness since childhood?" she murmured, then looked up at the vast sea. Her tone remained calm, but a hint of relief crept in. "So I could have flown... but this sky is too small to contain me."

Tianxing gazed at her and slowly spoke, "That's why I came from the outside world, for you. The sky isn't just one place; the world beyond is much wider."

The light on the sea surface shimmered in the wind.

"Yasuri Nanami, become my sword. I will provide you with a vast enough sky, and your talents can blossom here."

Silence once again stretched out in the sea breeze.

Nanami looked at Tengyo, then revealed a somewhat eager smile, as if something in her eyes had been ignited.

"Is this the reason you came here?"

She didn't press for details, as if asking herself or confirming something. After a moment, she slowly stood up, the sea breeze lifting her long hair.

"My Lord God, since you have pledged the heavens to me, you must take responsibility."

She raised her head, her gaze calm and resolute, as if she were making a vow, or as if she were accepting a challenge.

"Without any school or affiliation—Yari Nanashi, from this day forward, will serve you."

As soon as she finished speaking, she seemed to suddenly come to her senses, coughed lightly, and looked at herself with a serious yet playful expression.

"Ah, now I belong to the God. So—I am Amagi's subordinate, Yasuri Nanami. Please take care of me from now on!"

She paused for a moment, then looked towards the distant sea—the direction of Nana's journey.

"However, before I become your sword, please allow me to sever the ties of the past."

She smiled gently: "I'd like to meddle a little in my brother's journey."

"allow!"

Tianxing said loudly.

The sea breeze blew again, and the distant waves roared once more.

And at this moment, a certain predetermined trajectory quietly deviated from its course.
