This is a manga adaption of Ikuhara's new anime project. It's illustrated by Akiko Morishima, one of the most well known yuri mangaka.

Anyway, the first chapter is out. Kureha (the MC) is a pretty introvert girl and has no friends, so she calls herself "transparent." But lately this really popular girl called Ginko Yurishiro has taken an interest in her. Yurishiro seems to have a secret, but I'm not sure if the secret is that she's an alien bear like Kuraha thinks, or that she's in love with Kureha (probably both).
Anyway, the promotional picture features another "bear" girl, so I assume that one will be introduced later. It could be a love rival or something.
