When despair envelopes the world, no matter how people call, the world remains chaotic and crazy, and people pray for the arrival of light.

Until a beam of light broke through the darkness.

A traditional Cthulhu mythology background.

The protagonist is transformed into Ultraman through the system created by Hikari.

"I am Amatsuki Susumei, my profession is Shinigami." He is a Shinigami who survived the first Gotei 13. A close friend of Kirinji Tenjiro, and a shinigami enthusiast. Infiltrating the first Gotei 13, Amatsuki Susumei unleashed his instincts. For victory, to surpass Yamamoto Shigekuni, to surpass Aizen Sosuke, to surpass the Zero Division, to surpass Yhwach, and even, to surpass the Soul King! He must trample everything underfoot! "Toukai, immortal! Unohana Yachiru! Come and fight!" Amatsuki Susumei raised his Zanpakuto and declared.

Meiqian, a terminally ill patient, is bound to the [Naruto Live Streaming System]. In order to gain [Chakra Emotional Values] to prolong her life, she can only try her best to make a fool of herself.

Danzo: Am I the 5.5th Hokage? The First Hokage? Unbelievable!

One against seven: Forgive me, Sasgei, this is the last time...

Sasuke: My stupid brother, you picked my nose and expect me to forgive you?

Carrying the cultivation technique "Mysterious Origin Creation Manual," he transmigrates to Konoha in 1942 at the age of 6, becoming Uchiha Chen of the Uchiha clan. He grows up before the Third Shinobi World War, rises to prominence during the war, and hides in Konoha to cultivate immortality.

A programmer who was terminally ill for various reasons died and ended up in the year 0078 of the Gundam Universal Century.

Confined to classrooms, companies, and hospital wards during his lifetime, he wanted to use his knowledge of the Gundam world to travel around the world and explore the universe.

Of course, it would be even better if I could make a fortune along the way.

But this universal century seems different from the world he knew so well.

Is this 0079? Or GQuuuuuuX? Could it be the timeline of THE ORIGIN?

It can't be... that three timelines are mixed up together..., can it...?

[Adventures in the Roger Era] + [Gunslinger] + [Pure Devil Fruit Development] + [No System] + [Unchanged Power Levels]

Darrow travels to the world of One Piece and becomes the younger brother of Roger's wife Rouge. Fortunately, Roger has not yet conquered the Grand Line, so Darrow still has time to change his sister's tragic future.

With the power of the Compression Fruit and his innate Observation Haki, Dead Eye, Darrow grew step by step and made a name for himself on the high seas, writing his own legend in an era where heroes like Roger, Rocks, and Whitebeard rose to prominence.

The story begins with the crew's adventures (partially original storyline + extensive references to the old era in the manga), and after Roger's death, they become one of the Four Emperors and vie for supremacy.

[The strongest gunslinger] + [The most imaginative fruit development]

Arriving in the Naruto world, Hyuga Gen contracted the Byakugan bloodline disease from a broken moon core, becoming a notorious sickly child. To survive, he set his sights on the Root, hidden deep beneath Konoha... Hiruzen Sarutobi: As long as this sickly child lives, Konoha is safe. Danzo: That damned sickly child, he's fleecing me again! Orochimaru: Why is this sickly child causing trouble every day using my name? Akatsuki: How can my plan proceed if this sickly child doesn't die? They fear me, revere me, obey me. They call me the White Moon of Konoha, the controller of the Moon Land, the Lord of the True Moon. My name is Hyuga Gen. Anyone who dares to defy me, take my Moon Wheel Reincarnation Explosion first!

"Reincarnated into the Hyuga main family, becoming siblings with Hinata Hyuga. Knowing the plot's direction, Fuyuki is a little panicked... When the time comes, what should he do when the ancestor Kaguya rises from her coffin? Should he... accept the ancestor's lack of martial arts skills, or become the ancestor's obedient grandson? Fuyuki, holding the 'Summoning Scroll of the Whirlwind Demon Society,' fell into deep thought. ...Keywords: Naruto, Konoha"

The story begins with the Nine-Tails' rampage, but the protagonist instead goes to steal from the Fourth Hokage's house! Reincarnated into Konohagakure in the Naruto world, he's even a relative of Sakura Haruno! And a seemingly "ordinary" medical ninja at that. Watch how the protagonist uses his precognitive abilities to live a different life and save countless unfortunate souls…

The world of One Piece is amazing! I heard that everyone who transmigrates there can become a superhuman. Just eat a Devil Fruit and take off instantly? But the question is, where do you even find a Devil Fruit? Joining the Navy means you can learn the Six Powers and climb to the top of power step by step? But the Navy doesn't accept ordinary people! Can you just join any pirate crew and bully men and women? What if the main characters come to kill you? Find a kendo dojo and become a master, and with enough effort everyone can become Zoro? The physique of a transmigrator is worlds apart from that of the natives of the One Piece world! Ordinary transmigrators have terrible physical abilities, are considered undocumented and have no choice in their birthplace, and their only advantage might be their statistical attributes. It seems like a disastrous start, but it's actually just the norm for ordinary transmigrators. Is there any chance of survival in this situation? Yes! ...
