Background

Yu Chenluo, a medical student, transmigrated into Natsu Hiraku's body after the original Natsu's parents died. He retained fragmented memories of the host, including Natsu's unremarkable life as an ordinary high-school student with mediocre grades and athletic ability. 1

Following the death of his parents, Natsu awakened Cursed Energy and an ocular ability while killing a Cursed Spirit. Gojo Satoru noticed his potential, arranged the funeral, and offered him a place at Jujutsu High. 1

At Jujutsu High, Natsu initially could not control his Cursed Energy. Principal Yaga tested his resolve with an attacking cursed doll; Natsu's rage activated his scarlet Sharingan, allowing him to predict the doll's movements and dismantle it. He was accepted as a student afterward. 2

Natsu also has a playful, entrepreneurial side. He cooks for his classmates, attempts to sell cooking subscriptions, makes jokes during training, and willingly participates in his friends' teasing despite his initial reluctance. 8 14 118
