Classic route: go to the SoL first, receive daily Silver Tickets to get Normal Cat's True Forms, then unlock the Crazed Cats in the progress, you barely need any Ubers to get Ururun. Nekoluga alone is enough, you may need some Critical attackers...

Modern route: Beat the fourth Moon first, use tanky Cats such as Jamiera, Island and Valkyrie to beat Cli-One.
