Battle Cats - Festival mission Red Sky at Morning (Oncoming Storm) using only 1st Forms 

The main unit that's probably the most important is Kotatsu Cat. After sending out Kotatsu Cat and it stalls Perfect Cyclone, you can use rushers and time your cannon so they can get into the blindspot. You can also potentially use hacker cat to help deal with the peons that will get in kotatsu cat's way. Hacker cat has a very long range so it shouldn't get hit like how my Chronos did which have shorter range.
