Jellyfish Can’t Swim in the Night
夜のクラゲは泳げない• Yoru no Kurage wa Oyogenai
Synopsis & Story
"I want to find what I enjoy." Shibuya is a city full of identity. It is here on Shibuya’s late night streets that illustrator Mahiru Kozuki, former idol Kano Yamanouchi, Vtuber Kiui Watase and composer Mei Kim Anouk Takanashi — four young women who are slightly outside the world — join together and form an anonymous artist group called JELEE. “I” also want to shine like someone else. If it's not me but “we” then we might be able to shine. (Source: Crunchyroll News, HIDIVE, edited)
