Ichiban Kuji is a Kotlin-based application that allows users to collect action figures of their favorite anime characters. The app features a virtual coin system that can be used to either exchange for specific action figures or participate in a gacha system for a chance to obtain random figures, including rare and limited editions. Users can acquire these coins through in-app purchases using real money, enabling them to expand their collection more quickly. With an engaging interface and secure transaction system, CollectAnime provides a fun and immersive experience for anime figure collectors.
