I stumbled over two Cat's Eye manga on pixiv that I can't find anymore (as it didn't have the series as a tag). Maybe one of you recognizes them and can provide me with a link or post them here.

The first was a story of the three sisters infiltrating a building. Ai, the youngest falls on a pit trap and is impaled by spikes, the other two sisters are then cornered and killed by gangsters, one of them was a samurai looking guy who cut one of the girls with a katana.

The other was about the girls being cornered by gunmen and perforated in a hail of bullets before their corpses are placed on tarps and fucked before disposal

Both were in black and white and probably by the same artist
