Yurikuma Arashi (Japanese: ユリ熊嵐, lit. "Lesbian Bear Storm"^[2][3]) is a Japanese yuri anime television series produced by Silver Link and directed by Kunihiko Ikuhara. The series was first announced via a website in August 2012, where it was referred to as the "Kunihiko Ikuhara/Penguinbear Project." The series first aired in Japan between January 5, 2015 and March 30, 2015 and is licensed in North America by Funimation. A manga adaptation illustrated by Akiko Morishima was serialized in Gentosha's Comic Birz magazine between February 2014 and April 2016 and has been licensed in English by Tokyopop under the title Yuri Bear Storm. The name appears to be a reference to Akira Yoshimura's novelization of the Sankebetsu brown bear incident, The Bear Storm (羆嵐, Kuma Arashi), though any more concrete link besides the presence of human-attacking bears is only speculated.^[4]

The manga and anime versions have significantly different plotlines.

In the manga version, the shy Kureha meets the transfer student Ginko, who appears in her dreams as a bear princess. As Kureha becomes friends with Ginko and gets to know her, she learns that Ginko is wrapped up in her own world in which she believes everything is made up of bears.

In the anime version, humans have created a Wall of Severance to separate themselves from the bears, who grew violent and attacked humans after a far-off planet known as Kumaria exploded, turning into a meteor shower that fell upon earth. Two bears, Ginko Yurishiro and Lulu Yurigasaki, sneak through the Wall of Severance and disguise themselves as humans, enrolling in the prestigious Arashigaoka Academy and taking an interest in Kureha Tsubaki, a human girl who despises bears after her mother was killed and eaten by one.

Ginko Yurishiro (百合城 銀子, Yurishiro Ginko)

Voiced by: Miho Arakawa (Japanese); Monica Rial^[5] (English)

The first titular heroine and a bear who takes human form and transfers to Arashigaoka Academy, where she sets her sights on Kureha. It is later revealed that, as a bear, she was once friends with Kureha and her mother. At the end of the story, Kureha gives Ginko her promise kiss, and the two head on a journey beyond severance; Lulu states that no one knows what has happened to them afterwards.

In the manga, Ginko sees every living thing as bears, believing Kureha to be her fated one, as Kureha is the only one who appears human to her. Ginko assumes this is because the entire world is made up of bears and only she, her mother, and Yurika can see the world for what it truly is, being descended from the royal family of the forest. However, it is later revealed that the "bear universe" is just a delusion implanted into her by her mother, Kale. She later regains her memories, remembering that Kale was responsible for the death of Reia, and tries to distance herself from Kureha.

In the manga, she introduces herself as Ginko's childhood friend and alleged "lover" who once served under her as a maid, but Ginko apparently has no memory of this. Lulu is much more eccentric in the manga, and views Kureha as a rival for Ginko's love, though the two become friends anyway.

In the manga, she is a shy girl who wears glasses and a ponytail.

Since eating Reia did not satisfy Yurika, she presently plans to thus make Kureha her "bride-in-the-box" and eat her, and manipulates several of the students to achieve this end.

The series has been praised as tackling the "prejudice facing gay people in Japan"^[21] while simultaneously being a "moving tale of prejudice and fear and love" which focuses on cultural treatment of all women, especially those who are lesbians, criticizes the "idealization of female innocence and purity," and serves as a study of bigotry.^[22] Further reviews praised as a well-written drama which is "densely packed with social commentary, multivalent symbolism, and references to historical events, [and] literature,"^[23] is LGBT-friendly,^[24] and is "all about lesbians."^[25]
