Shizuku
Shizuku is an alternative method for installing and updating extensions in Reikai.
It taps into system APIs to directly install packages without requiring user interaction.
To get a detailed understanding of Shizuku, its purpose, and how it operates, refer to the information provided here on Shizuku.
Setting up Shizuku
To set up Shizuku, follow the instructions here on Shizuku.
After configuring it, enable Shizuku within Reikai by navigating to then setting Installer to Shizuku.
Manga extensions only
Light novel plugins are JavaScript that installs inside the app, so no installer setting touches them.
