With Genshin Impact 2.5, HoYoverse introduced a version of Kazari’s Mask that players can use as a piece of furniture in their Serenitea Pot. To receive the mask, the player must first complete the Sacred Sakura Cleansing Ritual.
The Sacred Sakura Cleansing Ritual is a lengthy quest that the player will need to complete upon first arriving in Inazuma. Once completed, the player can visit the Grand Narukami Shrine, where they usually talk to Mae Yiko.
Find Inagi Hitomi, one of the shrine maidens, and talk to her. She is usually found near a waypoint that the player can use to teleport to the temple. All you need to do to get the mask after completing the long quest is talk to her. The mask is fully crafted, so you can put it right in your home.
