Anime Crossover Across the Heavens: Sign In, Starting with Naruto

Ye Feng transmigrated into the world of Naruto and was bound to a System that made him stronger every time he checked in.

From then on, in all sorts of strange places across the shinobi world, people would see a young man carrying a sword.

Uchiha Madara said, "I hear Ye Feng's eyes are called the Tenseigan. I don't know what they are, but they're definitely no weaker than my Rinnegan."

Orochimaru said, "If Ye Feng's swordsmanship weren't so terrifying, I wouldn't care about the Uchiha clan's pretty eyes."

Jiraiya said, "Forget everything else. When it comes to writing, I, Jiraiya, admit that Ye Feng is the best!"

The Eight-Tails' jinchuriki said, "It brings tears to my eyes... I might've just been in the way of his sign-in, and then he stole my disciple from me."

My name is Ye Feng. Feng, as in riding the wind and breaking through the waves.

My rules are simple: if anyone stops me from checking in, I'll make trouble for them.
