The Puppeteer

After dying at the hands of Haruno Sakura, Sasori no Akasuna-once an S-ranked criminal and master puppeteer-awakens in an unfamiliar world. Stranded in the midst of Final Selection, he quickly realizes he has been thrust into a new reality, one where demons lurk in the shadows and swordsmen wield techniques unlike anything he has seen before.

Forced to adapt, Sasori takes on the role of a Demon Slayer, concealing both his past crimes and the truth of his existence as a living puppet. But his carefully constructed facade is shaken when he encounters Rui, a young Spider Demon who fixates on him, declaring Sasori his new father. Initially taken aback by the boy's attachment-and the fact that he is a demon-Sasori makes a choice that could cost him everything.

He secretly takes Rui on as an apprentice, drawn to the eerie parallels between the boy's fractured soul and his own.

As their bond deepens, Sasori begins to question his own nature and the rigid divide between humans and demons. But when their secret is discovered by other Demon Slayers, he is faced with an impossible decision-protect the only one who has ever seen him as more than a weapon, or uphold the role he has claimed in this world.

In a world of black and white, Sasori walks the thin line in between, but how long can he keep his strings from snapping?
