Chesed

Chesed is the second raid boss in Blue Archive

The boss consists of two stages: For the first stage, you will face waves of Heavy armor enemies until you reach the boss room where Chesed is located for the second stage of the bossfight where you have to clear all the robots to build the stun gauge and reveal the unprotected core with zero defense when the bar is maxed out. The core will stay revealed for a period of time and then it will protect itself again, forcing you to repeat the process if you want to have it reveal itself again. The boss has extreme defenses while protected so it's reccomended to focus on clearing the enemies instead to build gauge quickly.
