Kawaii Co has developed a free personalization application for Android called Fan Anime Live Wallpaper of Ruby Rose. This app features a kawaii anime live video wallpaper with support for phones and tablets. The wallpaper can be customized according to the user's preference by disabling the sliding between screens and changing the frame rate in settings. There are no in-app purchases, making it absolutely free to use.

This app is perfect for fans of Ruby Rose, the main protagonist of the popular show RWBY. Ruby is known for her High-Caliber Sniper-Scythe (HCSS) known as Crescent Rose, and her fair skin, silver eyes, and black hair that fades to dark red at the tips cut in an asymmetrical bob. Her outfit is topped by a red hooded cloak fastened to her shoulder by cross shaped pins.

Overall, Kawaii Co has done an excellent job in creating a high-quality live wallpaper that is sure to impress fans of Ruby Rose and RWBY.
