This run is done with no resets, ez to clear challenges if you know what you are doing.
Gimmicks:
Challenge 1 & 3: Sleepge
Challenge 2: Killing a Black Tortoise mob produces fire, so healing is a must to keep yourself on top, Atsuko is good for her passive healing, but you can also use other healers too. MG also make quick work for killing mobs faster.
Challenge 4: Destroy drones to put dmg reduce on the boss, killing an MG mob here will produce fires that can kill drones faster, Tsukuyo can bruteforce this challenge but you can also use other units for this.
Challenge 5: After a certain time, the cart will start shooting constantly at you, and there are 2 healing generators that you can use to mitigate the damage, and also, remove the mobs as soon as possible cause it will burn your units if they get close as they die.
My previous challenge clears for this event:
Challenge 2: • (Old) Blue Archive - Playing Tag at N...
Challenge 3: • (Old) Blue Archive - Playing Tag at N...
