In July 9th and 10th, 2016, the co-sponsored (between Nyanko Daisensou Developers and Indle Game Festival) Indle game festival "BitSummit 4th" was held in Kyoto's Event Hall "Miyako Messe". To commemorate, a time-limited Special Stage called 協賛BitSummit記念！ appeared in Legend Stages. Completing the stage would grant a Rare Cat Ticket. The event has returned every year since then.
