Episode 0 of Gatchaman Crowds Insight to be streamed on Hulu before the airing of the main series.

Every day, a young girl wearing a mask stands by the beach and sings a nostalgic melody. After experiencing two sudden heart-wrenching partings when she was only a child, Nino Arisugawa has been singing her songs to the ocean, bound by a promise made with her two childhood friends—her first love, Momo Sakaki, and a boy who composed music, Kanade "Yuzu" Yuzuriha. Having never met each other, the boys both individually promised that if Nino was ever separated from them, her voice would be the beacon to reunite them once again. After six long years, destiny has finally placed Nino, Momo, and Yuzu in the same high school. However, the passage of time has changed many things in their lives—while Nino relentlessly attempts to fulfill her childhood promise with the boys, Yuzu's feelings for her from the past resurface, and Momo goes to great lengths to prevent a reunion with Nino. Through music, will they be able to mend their friendship and overcome all the feelings involved in this complicated love triangle?

The hilarious everyday lives of ancient deities and mythical creatures in the modern world. Super simple setup. 5 minute long episodes that center around the daily life of mythical creatures, deities and demi-gods who live in modern society in the human form, or a form that mildly reminds humans. The entire series consists of around 1 minute-long gags that show us fractions of the daily lives of our main characters. These follow the overall story line in a manner that makes the overall structure seem closer to continuity than episodic. The events vary greatly from our characters building snowmen in winter scenery to office parties and character specific problems that can only be solved with the help of friends. Most of the events are rather cute and heartwarming while the atmosphere is consistently comforting. That's pretty much the only noteworthy side of the story, and those who don't find this to sound interesting at all, most likely won't find any beauty from it.
