Asakusa Midori wants to create an anime, but she's too disheartened to make that first step by herself. By pure chance, she meets Mizusaki Tsubame, an up-and-coming socialite secretly dreaming of becoming an animator. Together with Midori's money-loving best friend Kanamori Sayaka, the energetic trio slowly work towards making their "ultimate world" a reality!
Episode 1:

This gave a strong feeling of 'anime of the season'. Although I think the main girl's voice sounds too much like a boy.

Animation is great, characters likeable, and the story has an unpredictable flow which made it feel like a Ghibli production.

Ofc, the opening is an absolute highlight, too.
