In Naruto: Reborn With Talent - Chapter 274 - Ch274. The Source

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…

Transported to a rural family in 1973, where eating required food stamps, dressing needed cloth tickets, stepping out asked for a letter of introduction, doing business was considered speculative profiteering, and securing a job demanded an urban household registration. She, a young girl from the countryside, faced an indifferent mother, a troublesome younger brother, and an elder sister who often had poor ideas. Life had become insufferable.Memories from her past life are mostly forgotten, yet the myriad of objects in her magical storage ring baffles her greatly.

[You have been killed by the Hero of Light.]

[You have died.]

I had died at the hands of the main character in the novel I had read before.

But I got another chance. I regressed and returned to the time when I first entered this novel world.

Once again, I live in this novel world as an extra character.

Since I have experience and knowledge, especially my World System which had upgraded, I'll do what I want to do.

I will become stronger than the main character.

Standing before you are:

Guardian and patron of darkness,

Disruptors and Reshapers of Order,

creator and persecutor of licking dogs,

The tea master, the goddess of the dark night, the nightmares and gravediggers of the gods,

The true ancestor of blood – Charlotte de Castel.

With madness, with blood, with curse, with destruction.

This is a legend belonging to the blood family…
