A stranger who traveled to the ninja world inherited the character card system, allowing him to transform into the character on the character card.

S-class, A-class, B-class, C-class.

Overlord Body, Cyclone.

Ape Demon, Crow.

Different levels of ninjas, unique secret scrolls, and powerful summoning beasts.

As Sanshui gradually uncovered the system's secret functions, he discovered that he had already surpassed everyone else.

“My name is Yuanshang Sanshui, you can also call me Fifth Generation Lord.”

Because of an accident, Tang Zijun traveled to a parallel world.

Traveling with him was an unknown Kamen Rider Belt.

After realizing that there was a strange inner world called the Mirror Plane hidden beneath this world, Tang Zijun spent several years alone to successfully eliminate all the monsters in the Mirror Plane.

At the same time, he is gradually adapting to his new identity.

Just when he was living the peaceful life he wished for, Tang Zijun accidentally discovered his sister's secret - she was actually a magical girl!

Could it be that there is a faction in this world that even he doesn't know about?

Are there more evil monsters than just one in the Mirror Plane?

Was I going to have to watch my sister live the same dangerous life I had before?

Regarding this...

A most mysterious organization has emerged on the mainland – "Akatsuki".

No one knows who its leader is; all that is known is that its members are all monsters.

The runaway prince is being hunted down by the Tsukuyomi ninja "Uchiha Itachi";

An impregnable fortress was reduced to ruins by the art demolition expert "Deidara";

The ruler of the deep sea was slain by the tailless tailed beast, Kisame!

As for me, Ye Chen, the creator of "Akatsuki," I simply watched calmly from behind the scenes as my reputation soared.

"My chess pieces are now scattered throughout the world."

Transmigrating to the world of Bleach, he became Kyoraku Shunsui's nephew, Kyoraku Tokimura, and was bound to a check-in system—getting stronger by checking in—and even obtaining a unique time-type Zanpakuto. Time reversal, time stop, timelines severed… However, in the perilous world of Bleach, for his own safety, he decisively chose to join the Fourth Division. You say I'm lusting after Hana-nee's body? You bastard, I just want to develop better in the Bleach world! Wait, it's actually pretty good…

After Wen Yao arrived in the Hell of Gensokyo, Shiki-sama's daily life became like this: In a singularity, discussing the meaning of death with Ereshkigal, the goddess of the underworld; Izanami, the goddess of the underworld, confiding in someone about her loneliness in a broken world; exploring souls and the abyss with Ash (primarily Gensokyo)... Primarily Gensokyo, interspersed with other worlds, the narrative will likely not follow the above pattern. A mix of first and second settings, the setting is not rigorous (updates will be irregular for now; daily updates will resume after the previous main story is completed; I will try to maintain uninterrupted updates during holidays). PS: If Shiki fans can't find any Shiki-sama fanfiction, they'll have to write their own. PS: I'm bad at creating summaries; this is not the final version.

Transmigrated into the body of Uchiha Kagami, an orphan from Konoha, burdened with a disability, he faces an incredibly difficult start. Relying on his forensic mind and scientific methodology, he resolutely embarks on an unprecedented path as a ninja.

He eventually became a powerhouse surpassing the Kage level, joining forces with the Fourth Hokage and the Legendary Sannin to completely revolutionize Konoha and lead the ninja world towards an unknown new era.

The protagonist travels to the world of Dragon Ball and becomes Piccolo Daimaō.

Although they faced the crisis of being defeated by Sun Wukong right from the start.

But as a transmigrator, our Piccolo the Great Demon King naturally also has a system.

With the system's help, Piccolo easily turned the tide and successfully defeated Goku right at the start.

...

"Piccolo is too strong, we are no match for him at all!"

"Is this the power of a Namekian with super-genius combat skills?"

"Sigh! Even if I become a Super Saiyan, I still can't keep up with Piccolo's pace of getting stronger!"

When a musical prodigy comes to the other side of the sea to pursue his dreams, he unexpectedly becomes a teacher at the Moon Forest.

What?! Me, a grown man, going to teach at an all-girls school? Really?

What? My students formed a rock band? Really?

What? The keyboardist ran away? The band broke up? Is it true?

What? My student has formed another band? Really?

What? My student is lost? What does that mean?

Amidst repeated shocks, Du Feng, holding the brown-haired girl in his arms, suddenly realized...

Wait a minute? Wasn't I supposed to be forming a rock band? Where did this come from?
