How to Change Endministrator's Identity in Arknights: Endfield

Want to switch up your hero, Endministrator, in Arknights: Endfield? First, level up your Authority to 15! If you're not there yet, explore Valley IV for chests and missions. Once you hit Level 15, tackle the Work Preparation mission to reach the Protocol Singularity room. There, you can change Endministrator's gender with a giant crystal! Just remember, there's a 24-hour cooldown before you can switch back!
