Taimanin Yukikaze: Taimanin Sinks into Hell

Taimanin Yukikaze: Taimanin Sinks into Hell is the official manga adaptation of Taimanin Yukikaze. It was originally published in Heroine in Trouble (ヒロインピンチ) Magazine in chapters and later bundled as a single release with an extra chapter.

Differences to Game:
The manga follows the same plot of Taimanin Yukikaze but skips the beginning confrontation with Yazaki Muneichi. In the first chapters it switches between the mission explaination of Asagi, Yukikaze and Rinko's good bye and their arrival at Yomihara and Under Eden.

Going over the contract and multiple scens in the visual novel closer than the OVA, it follows a bad an alternative bad end route simular to Rinko's bad end.

Mizuki Shiranui shows up like in the visual novel but has sex at the same time with Rinko and Yukikaze. Akiyama Tatsurou tries to attack Real but is knocked out by Rinko.

However, unlike the normal Rinko ending, it seems to follow an alternative neutral ending in which new videos are uploaded of their training. Without arriving later on, back in Gosha Academy.

The extra chapter just shows more single page training moments.
