This Doomsday Series is a collection of chiptune or video game-like songs composed by sasakure.UK that talks about the gradual destruction of earth and humanity due to a war. The series covers the events of the previous conflicts, continues with the war itself, then with imminent cataclysm and finally the post-cataclysm period, with each event sung by a different VOCALOID representing different individuals, each one with their current circumstances, own convictions, goals, and message.
