Shuu is a member of the literary club that can’t write. One day, he gets a mysterious message on his phone from a girl called Eina, and from that impulsive contact, they begin to exchange messages. They talk of things like their shared interest in novels and grow close. However, when they try and meet, they discover a shocking truth. Eina lives… not in the present, but five years in the past! How will their love develop, parted by five years of nights…!?

Uchiha Natsuki obtained the power system, revived Uchiha, and created the strongest force in the ninja world.

Exclude me Uchiha? Sorry, we quit!

Whoever the garrison likes will go!

“Kakashi, Danzo was the mastermind behind White Fang’s death and was connived by the Third Generation. You actually worked for Konoha!?”

“Itachi, this time I will awaken the Eternal Kaleidoscope for you.”

“Bai, your actual combat ability is too weak. Please enter the Tsukiyomi space to practice for a few years.”

Sorry, we Uchiha have kaleidoscope per capita.

Who can fight in a group fight these days? Get on my shoulder!

Otsutsuki is coming to destroy the world, but you are still striving to be Hokage. There is something wrong with you.

Danzo: “We must not allow Uchiha to gain power!”

“Sir, Uchiha Fugaku has resigned from his position as captain of the Konoha Guard.”

“???”

Third Generation: “The position of Hokage will never be given to you as Uchiha!”

“Hokage-sama, Uchiha has withdrawn from the Hokage campaign.”

“???”

“Sir! Uchiha has established his own country!”

“What!?”

“It’s not rare for us Uchiha to use a Hokage as a treasure. Let’s wait and use him as a target.”

ps: Hizashi did not die simply because he wanted Neji to have a father.

Ten thousand years have passed since the founding of the Tang Sect on the Douluo continent, and it has declined. A new, proud generation of heaven’s chosen has been born. Can the new generation of Shrek’s Seven Devils rally the Tang Sect and once more compose the song of the Unrivaled Tang Sect?
