He is voiced by [Lanling Li](https://anilist.co/staff/188374/Lanling-Li) as a teenager.

A junior disciple of the Gusu Lan Sect. Born Wen Yuan, he's the last remaining blood descendant of the now-extinct Qishan Wen Sect. He was one of the Wen clan remnants taken in by Wei Wuxian shortly before his death, but he lost his home for a second time in the first siege of the Burial Mounds.

Discovered by an injured Lan Wangji who came searching for Wei Wuxian's remains in the aftermath, the then-three-year-old boy fell into a high fever and lost all memories of his past. He was then re-named to Lan Yuan and later presumably given the courtesy name Sizhui in the same year that Wei Wuxian returned to the living world.

- Mysterious Inscription Sect's third disciple
- Age at the start of the story: 19

He wears a navy blue version of the standard Demon Slayer uniform, along with a black and white pinstriped haori, the hem and cuffs of which are striped lengthways rather than vertically, which covers his hands. Obanai also sports bandages in place of the leg-wraps around his calves, as well as another set of bandages that cover his mouth, and blue-strapped zori on his feet.

He is also always seen with his white snake, Kaburamaru, wrapped around his shoulders.

Sai is the replacement of Sasuke Uchiha in Team 7. The name "Sai" is given to him for the purposes of joining the team. He was recruited at a young age by Root, which trained him to have no emotions so as to make it easier for him to accomplish missions. This lack of personality causes Sai to meet with hardship upon joining Team 7, as he makes the mistake of insulting the other members in an attempt to seem sociable. He tries to seem more caring by smiling, though his teammates come to dislike it due to his obvious insincerity. 

Sai is a talented artist, and claims to have drawn thousands of pictures. Despite the magnitude of pictures he has drawn, his lack of emotion makes it impossible for him to be inspired to give something a title, and thus all of his works are nameless.

The eldest of three brothers, owner of the Rubrub ability.

__Level:__ A

Mingfei Lu's older brother.

A member of 全性Quanxing who can lend others qi that makes them hunt other 异人outcast and drain their power, which he also receives as interest.
