A familiar, thin figure was standing at the doorway.

He wore a yellow and black square haori, and his long, deep red hair was unusually tied in a high ponytail.

He was holding a katana that he had never seen before.

That was the back view of his father, Tanjuro Kamado.

And facing Tanjuro face to face.

It was a man Tanjiro had never seen before, dressed in a black suit and wearing a small top hat.

Because Tanjiro fell in the snow, he couldn't see the expression on his father's face, who was turned away from him.

But he was able to see the other side.

—The man in the black suit, his red eyes revealing a look of horror.

That was an expression as if he had seen a ghost.

[System, Upgrade, Treasure Chest, Cheat Code]

Seven Nights transmigrated, and he brought a system with him.

The system has a cute loli voice, but it only urges Qiye to continue getting stronger.

The world of Naruto...

Eye techniques? Bloodline? Summoning beasts?

The system says it has everything, so it's giving the host an enhanced version!

Impure World Reincarnation?

System: How about a permanent control type Edo Tensei card? No side effects!

The world of Douluo Continent...

Martial Soul? Soul Bone? 100,000-Year Soul Ring?

With the system in hand, everything is a piece of cake!

I've heard that the Asura God breaks the law while enforcing it?

System: Host, get the hell out of here!

The rest of the world is still being sorted out...

Synopsis 1: "Next up, Xiao Qian!" "Battle Qi, nine...nine-nine-nine eighty-one levels?!" -------- Synopsis 2: "Xiao Qian, your exes have each built their own factions in the Great Thousand Worlds." "That's good, they should have their own lives and pursuits... So, what factions are they?" "Ni Gan City, Wei Gan Palace, the Qiankun Ruler Alliance." "You're really targeting me, aren't you?" Xiao Qian was speechless. -------- PS: Battle Through the Heavens and Martial Arts: Closed-loop plot, one million chapters in reserve, no bad endings. -------- PPS: Two excellent older books already written, experienced author of romance novels, completed with integrity.

I'm in the Honkai world, having just traveled through time. The question is, what's with this strange narration? [Take off! Take off! Such a wonderful start! Looking at this opening, you feel like your life is about to reach its peak.] No, it doesn't feel like it's taking off at all. Besides, the Honkai world is notoriously unfriendly to ordinary people, right? (╯‵□′)╯︵┻━┻. [There are many beautiful Valkyries to choose from.] [Even if you want to go big, there are Honkai Gods, Soulsteel Mini-Bishops, and Cyborgs as well.] [You feel like you're already fired up!] Not at all... Wait, Otto, you can do that? [Changkong City! The place where destiny begins! This is the perfect place for you to take your first step after traveling through time!] [Defeat the Herrscher of Thunder, then collect the Herrscher of Void and the future Herrscher of Reason into your crystal palace—the world is mine!] Wow, with this setup, you want me to go head-to-head with the Herrscher? I get it. You probably want me dead.

I traveled to a world dominated by summoned beasts. When you were breeding summoned beasts, I happened to obtain a Gundam Gachapon machine system.

Shoot! Hit the target! Strike for freedom!

Draw again! European Emperor picture! Unicorn!

While the roar of the dump truck crushed mortal bodies, Lu Ze's will burst forth into countless stars in the vast river of time and space. He transformed into freedom, shocking the past, present, and future... However... A perpetual repeater at the Shino Spiritual Academy: "My strength is limited, so I can't become a regular team member." The ramen shop manager in Konoha Village: "Fire Style controls fire, Wind Style wakes the noodles, and Water Style condenses dew. Only this kind of ramen is chewy!" An ordinary clerk in a tavern in Windmill Village, his pupils reflecting the silhouette of the future: "Two guests from the southwest, arriving in one minute." An ordinary cave explorer on the first floor of the Abyss: "I'm just a scavenger. I earn enough to pay for my medical expenses and call it a day. I will never touch the deep curse." An ordinary fighter who travels back and forth to earn money on the first hundred floors of the Sky Arena: "I dare not fight. I just need to eat and eat." One day, the newcomer Lu Ze said, for some unknown reason: "Why are you playing it down?"

"That year, I saw the students of Class B slumped in their chairs, sobbing uncontrollably. That scene is unforgettable. At that moment, I thought, if I could become the class president of Class B, I would lead Class B to victory!" "So, Ichinose, let me be the class president of Class B." "No, Uesugi-kun, you're too radical." "Ichinose, you'll regret this!" "Uesugi, I am the class president of Class B." *Slap!*... "Hmph, naive Ichinose, do you think I can't do anything if you don't agree? Shibata, notify Kanzaki to prepare to close the net!" "Uh, um, Uesugi—" "Shut up, Shibata, this time we must act quickly. Before Ichinose can react, expel them from school. I want to see who can stop me this time." After a while, "The wind on the rooftop is so strong..." "Uesugi, come down quickly, I will never reveal your plans to Ichinose again." "You write it down!!"

He transmigrated to Konoha Village, becoming a cannon fodder genin. The Second Shinobi World War raged on, and Natsume's ninjutsu consisted only of the D-rank Three Body Technique and the C-rank Earth Release: Wall. His superiors were utterly inhumane, always using him as cannon fodder, forcing him to narrowly escape death on almost every mission. Natsume felt he could die at any moment. Fortunately, the "Good Boss System" activated. By sacrificing his direct superior or seizing their position, he could gain a chance to win rewards. Sacrificing a Chunin captain granted him the Kagura Mind's Eye. Sacrificing a Special Jonin captain granted him a Jonin-level chakra. ...When the death rate of Natsume's direct superiors became extremely high, he finally faced questioning from Konoha's higher-ups, "Natsume, we need you to explain why your superiors' casualty rate is so high?" "Because they deeply understood the Third Hokage's..."
