To summon more characters in Anime Warriors, tap on the Summon button on the bottom left-hand side of the screen. Choose your banner, whether it's Anime Mashup, Shinobi Storm, Pirate Plunder, Saiyan Rush, or others. You can summon one at a time for 50 Crystals or ten at once for 500 Crystals. You have a chance to unlock common, rare, super rare, epic, legendary, and ultimate characters with each summon.
