241,500 is all you need to max coins. Unless you enjoy CBT, take it easy and do 3 comfy runs.

- A Lv1 1111 1* Mari will cleanse 1 debuff just as hard as a lv90 5MMM UE60 Mari, for example.

Tips

Defense Exercise is a wave exercise. After destroying enough bots, another wave will spawn.
- Getting as far ahead as possible will allow for spawn killing, resulting in faster clears. Aoba, A.Hoshino, D.Tsukuyo are great at this job.
(Stage 3+) After a specific student destroys 20 bots, she will receive a 25% damage debuff, stackable 3 times. When cleansed, she will receive a 75% damage buff for 10s.
(Stage 4) Barriers receive 30% less damage, and bots do 4x damage.
