Foreword: I keep exploring the vast vaults of Silky's games. This time it's even more suspicious work - a full scale yuri game. But it has many SF elements and even has genetically modified mutants - knowing Silky's they would not settle with an ordinary yuri work.
Foreword: There is a negative English review, but VNDB voting shows a decent 6.72 score atm and this is Silky's story oriented work, same Silky's that I praised multiple times for Kawarazaki-ke no Ichizoku, Reira Slave Doll, Ushinawareta Rakuen and Koihime. So I decided to make it to the end of Jack ~Haitoku no Megami~ no matter what.
