In this new and vast world, he tries his best to get used to his new body and get stronger along the way. With his overpowered system and skills. To one day become untouchable.

When a Demonic Assault occurs, most people stuck inside of a Fracture end up hiding inside of a bunker in the hopes that they don’t end up killed by a demon.

Others might even hope for the slightest possible chance at signing a contract with a spirit and becoming a Guardian.

So when Scarlet was caught in a Fracture, the last thing she expected was to become a demon herself.

Exactly two centuries ago, humanity was struck with their very first Demonic Assault.

The skies above the capital of the US, shattering as if made of glass; demons of all kinds appearing out of nowhere; and no way to effectively stop them before the end of the Assault.

On the brink of devastation, some of the humans managed to find themselves offered a contract whilst inside of a Fracture. One bringing a chance at power, fame, and fortune.

Now, long after every nation of the world joined together to form the Terran Republic, Scarlet finds herself stuck trying to find a university from the Republic’s capital that will accept someone from a lower tier city into their midst.

In order not to become Danzo’s consumables, Mu Yue worked hard to teach and increase her strength.

“Complete the teaching rated A for the first time and receive the reward – mastery of fire attribute chakra properties change.”

“Under your guidance, Uchiha Shisui has worked hard to practice, and his overall strength has been greatly improved, and he has been rewarded – the Immortal Human Body!”

Under Mu Yue’s guidance, Zhishui understood that the village’s enemies were not necessarily other big countries, but could also be within the village. People who spoke righteously about the will of fire might not necessarily act in accordance with the will of fire.

Obito got rid of the title of being the weakest person in the ninja school, and Metkai became a master of physical skills even earlier…
