Naruto: The Life Changer - Chapter 73 -:

A series of short stories in the world of Toaru Majutsu no Index organized into chapters featuring Kanzaki Kaori as the protagonist, going around the world and space doing missions for the Church of Necessary Evil, however, there is more than meets the eye as each incident is connected.

One chapter was bundled with each limited edition release of the Toaru Kagaku no Railgun anime DVD and BDs, with all of them together being equivalent to a single normal Toaru Majutsu no Index volume

When Fang Zheng opened his eyes, he was surprised to find himself reborn in a fantasy world of magic, dragons, knights, and princesses. Not only that, but even the game system that Fang Zheng had designed before also followed him into this world. Then, his next step would be to traverse thousands of plains, gain endless strength, become a brave hero, defeat the devil, marry the princess, reach the apex in life… wait, wait, wait, before all that, why was he reborn as someone who everyone called a cultist?

Through Naruto, I like to mention the super krypton gold system, as long as krypton gold can become stronger!

Uchiha Natsume, who has praised the lucky money for ten years, finally opened the [Kaleidoscope Writing Wheel Eye]!

Next, what about Flying Thunder God, Immortal Mode, Bamen Dunjia, Samsara Eye, Heavy Particle Mode… I want all of them!

From today, I will never be Konoha’s licking dog again!

Defeat Fuyue, fight Sarutobi, kill Danzo, betray Konoha… Whoever stands in my way and betrays the village will die!

Life and death are bearish, if you don’t agree, just do it!
