In early 2022, Pink Pineapple and the sales agency (MS Pictures) released a brief statement (primarily on their official blogs and via adult retailer newsletters). The statement confirmed that the final episode was delayed indefinitely due to "production circumstances."

However, industry insiders pointed to two more specific reasons:

Given the information above, if you're specifically looking for Episode 3 from 2021:

False. Due to the complexity of adult animation, no fully realized fan-made Episode 3 exists. There are fan-fiction scripts and AI-generated storyboards, but nothing playable or watchable.

Partially false. Pink Pineapple is still operational as of 2025, though they have slowed down new production. They have not gone bankrupt, but they have shifted focus to re-releasing older catalog titles rather than funding new animation.

If you have watched Episodes 1 and 2 of Kuroinu: Kedakaki Seijo wa Hakudaku ni Somaru, you know that the story ends on a massive cliffhanger. Episode 2 concludes with the fall of the main defensive line and the capture of the lead heroine, Princess Prima.

Episode 3 was intended to cover:

Because Episode 3 was never produced, the anime version of this specific visual novel route remains unfinished and essentially cancelled. There is no resolution within this 2021 adaptation.
