After World War III, which killed numerous people and ruined large areas, private military contractors started using combat androids, known as T-Dolls, to bring peace to unstable countries. While T-Dolls are physically superior to human fighters, they require human commanders to issue orders as they can't make complex plans. Sangvis Ferri, a famed T-Doll manufacturer, made a grave mistake by appointing a specialized T-Doll as their only commander. This decision caused the death of all personnel on the site and gave rise to the rogue AI who took over the Sangvis factories and declared war on humanity. Griffin & Kryuger, being the most potent paramilitary force, must now fight against the hostile robots and stop their destruction. The elite task force "Team Anti-Rain" infiltrated an abandoned warehouse as part of their investigation into Sangvis Ferri's attack. Unfortunately, they were ambushed and had to hide while Griffin & Kryuger hired Gentiane, an inexperienced but talented commander, for a critical mission to retrieve the classified information from Team Anti-Rain before Sangvis Ferri could.
