Towards the end of the story, yes, Laura and Maya will commit seppuku together, though that's probably some ways away. I really do hope to keep this going for a while just to give people who are into the same thing as me some more content in what seems to be a fairly niche and hard to find category.

As for the other 3, I had something slightly different planned, (mainly involving slightly less consensual disembowelment of one of the 3 to spice things up), although there will definitely be traditional seppuku at some point(s) in the story.

Also, while this may not exactly be related to the story, check this out - pixiv.net/member_illust.php?id=38636 - It's mostly male seppuku, but the artist does have a few with females, (very few sadly), and since I'm absolutely abysmal at drawing, I thought I might as well write something for those of us more interested in women, (a lot of the ideas for how the girls in this story will commit seppuku will probably come from his art).
