Vendemiaire no Tsubasa

Sirius no Kizuato

both about mechanical girls, wings of vendemiaire comes from the twisted mind of Bokurano and Narutaru creator, Kitoh Mohiro, so expect a whole different level of story.
very superficial similarity, but the twisted world of Sirius' Scar comes as an echo for the twisted characters you encounter in wings of vendemiaire. both makes you wonder deep about fate and consequences of your actions.
