But it's not as sweet as you think…
Kodoani.com – September 6 is Sister's Day in Japan, and the anime My Deer Friend Nokotan commemorated the occasion with a new image that is both dark and lovely. The image was posted on the account X official of the film, titled: “Torako Koshi Can't Rest Because Her Yandere Little Sister Loves Her to Death.” This event would seem to disappoint characters like a former student council president, but would certainly please her beloved kunai-wielding little sister.
Based on the manga series by OshioshioMy Deer Friend Nokotan is directed by Masahiko Ota (Himouto! Umaru-chan, Onipan!) WIT Studio. The story composition part is by Takashi Aoshima Responsible for, character design by Ayumu Tsujimura performed by, and music by Yasuhiro Misawa (HINAMATSURI) composed.

However, her peaceful school life is turned upside down when she runs into Shikanoko Nokoa girl with strange antlers! Trouble always seems to follow this doe-eyed girl.
