Forgot name of the manga

[Oukishi]

Can sb help me find this horror/tragedy-ish manga series? I remember it's protags were girls, and in a arc one of the girl went into a church/cult that was for widows and each girl assigned a name of a flower, and then they discover some girls were turned into fertilizer for the flowers. Tyvm and merry xmas

I think you think Murcielago. If it turns out that's it, then that was some pretty vague description that left out very important details.

Yes it was Murcielago, thank you for finding it! And I can't help but forget some details since it's been a while since I last read it, and well, that arc stated before is the only thing that pops up from memory. Thanks again @mikegnesium
