This work is a manga version of a PixivRequest illustration( https://www.pixiv.net/artworks/98962809 ), and is available in PDF format for paid plan members only.
In my own game BluePort, there is a scene where one of the heroines, Ai, is captured and interrogated by the enemy. What if she drowns in that scene? I made a manga of this situation.
The number of pages is 12. (including front and back covers)
This work is originally intended for all ages, but has a rating of R18 due to hard drowning expressions. Please be careful if you dislike it.
...By the way, this manga does not have a tragic ending.
