How old is Sayu in Genshin Impact?

The community's favorite ninja girl, who's mostly known for lazing off in hopes of growing taller, as well as being voiced in English by popular Twitch streamer Lily "Lilypichu" Ki, Sayu has recently emerged onto the Genshin Impact scene as one of the game's best support options.

How Old is Sayu in Genshin Impact?

At the time of writing, although Sayu's birthday has been confirmed to be on Oct. 19, miHoYo has yet to disclose exactly how old and tall the 4-star Anemo Claymore character is in Genshin Impact.

However, due to conversations travelers can have with Kano Nana, the NPC located in Grand Narukami Shrine, Inazuma, it is inferred that Sayu is indeed a kid who should be in the ballpark of Razor, Bennett, Xinyan and Barbara (potentially) as one of the youngest playable characters in the game when considering biological and chronological age.

Raised since she was a child in the Shuumatsuban—a secret organization in Inazuma under the Yashiro Commission—Sayu is said to be extremely loyal to her group. However, her most prominent trait is not that admirable loyalty, but instead laziness.

Sayu believes that sleeping can help her grow taller, which is why she's long mastered the various arts of ninjutsu (e.g. escape techniques and aura adjustment) to hide and doze off.

When is my growth spurt gonna come? Everyone my age [is] practically twice my height, and I'm still... Ugh, enough, I need sleep, sleep is the answer. Good night!
