Genshin Impact just released the gacha banner for Yoimiya, which also includes new 4 star character Sayu, an Anemo vision holder, and a kunoichi from Inazuma - One Reddit fan managed to find a particularly fun and cute bug which unveils one of Sayu's secrets.

Reddit Genshin Impact player manages to find a new Sayu idle animation bug

Sayu, just like every other Genshin Impact character, has a special idle animation. As in, an animation that triggers when you aren't moving the character around nor doing any action. In Sayu's case, she uses her ninjutsu to camouflage as a tanuki, the mystical animal her costume and all her ninjutsu are based on.

You definitely know what's a Tanuki is if you've been watching anime for, let's say at least 5 years. Since it's a pretty common creature in Japan's folklore. If you played through the Kazari quest in Inazuma, one of the best quests in Genshin Impact so far, you should have learned what a Tanuki is too. If you still don't know though, I suggest watching Pom Poko, a movie that was directed by the late Isao Takahata at studio Ghibli.

Anyways, when Sayu triggers her idle animation she hides inside a tanuki-shaped ball. And one player on Reddit,

Update: Execpt Sayu's outfit isn't designed around the Tanuki but the Mujina, which look extremely similar and are often mixed up together. You should still watch Pom Poko if you haven't yet though.

More on Sayu, Genshin Impact

Did you pull the Yoimiya banner for Sayu? Personally, I definitely advise against doing so unless you also want Yoimiya herself. It's much more efficient to wait for Sayu to get on the Standard Banner and try your luck there.

Genshin Impact is currently in its Version 2.0 which added the Inazuma region, Kamisato Ayaka, Yoimiya, and Sayu as playable characters. Version 2.1, according to leaks, will add the three leftover islands of Inazuma. miHoYo also already officially confirmed the Raiden Shogun, Kujou Sara, and Sangonomiya Kokomi will be added via new banners.
