After the 'Planetary freezing' in 2047 Ishitar planed a project with engineer Alita The human conservation project, The plan is to save 600,000 datas of brain informations and DNA samples using 12 Ark servers However, problems are began to arise. Datas that maintained a life in Ark server began to give up their lives one day. The loss rate increased overtime and it became a serious trouble for Ishitar.
One day, Alita came to Ishitar and proposed the plan that was so bizarre but tempting offer. The plan is to emphasize the survival of datas.
The plan is called as "Parablum simulator". In Parablum simulator, there will be an enternal war. Datas fight for survival from conflicting sects.
Ishitar accepted Alita's proposal In 2252, 12 Ark servers have been separated into various sects and declared the war in the Parablum simulator.
