An order drops: upgrade the Firestorm‑3 into something better within a month. At the briefing Estrad's MRLS is shown and Mr. Culley suddenly goes pale. Staff learn Carolyn, the unit's Northern expert from Titan Brigade, was hit and killed while leading repairs. Culley remembers a past life where a Resistance War broke out six months later; lacking firepower cost many lives and pushed him into lifelong weapons research. Now returned to the Founding Era, he vows to build their own MRLS. General Llyod agrees, leaving the team racing against the one‑month deadline.
