Quick answer
Grow Up Show: Himawari no Circus-dan premieres in July 2026, and new ads reveal the theme-song artists. The original circus-troupe anime joins a crowded Summer slate; the streaming platform is still to be confirmed.

Original anime carry more risk than adaptations, which is exactly why they are worth tracking, a circus-troupe premise has room to surprise. The theme-artist reveal is the production's first real pitch for attention.
What the ads confirm
Theme-song artists and a July window. Full cast and the streaming home were not detailed here.
