How to Counter Black Enemies in Nyanko

First, when you enter Nyanko's World, Future, or Cosmos chapters, you'll see three buttons: 'Start Battle,' 'Power Up,' and 'Character Formation.' In the middle of the screen, there are two large doors. If you pull the handle of the right door to the right, you'll hear a 'meow~' sound and see a black cat. If you pull the handle 60 times within 60 seconds, making it 'meow' each time, you can obtain the EX character 'Cat Flower.' Its first form is a bit weak. However, on the 22nd of every month from January to December, if you access Legend Story, a stage called 'Cat Flower's Attack(?)' will appear for just 1 minute. Clearing that stage unlocks its third form. The third form, 'Cat Bomber,' is an effective unit for mass-producing black enemies and is a strong stopping character frequently used in the later stages.
