[Mecha + no System + one heroine + Gundam-esque + urban + no transmigration + no rebirth + alternate world]
Blue Star's fossil fuels are gradually running out. The Lighthouse Covenant Federation is the first to develop the mecha “NFT,” changing the balance of power in the world. Kahn, son of a federation hero, joins the Crimson NTF Training Base. From that point on, the world's schemes and conspiracies will gradually be brought to light...
Standard Synopsis:
In Year One of the RN era, after Blue Star's fossil resources were depleted, the world consolidated into three major factions: the Tower Covenant, centered around Lighthouse Nation; the Human Alliance, centered around Dragon Nation; and the Pan-Western Alliance.
To resolve the energy crisis, the Pan-Western Alliance deployed troops to the small nation of Finan under the pretext of providing aid. In truth, it wanted to mine the vast mineral deposits discovered in the region, sparking an economic uprising in Finan.
Hyperion Corporation, a subsidiary of the Lighthouse Federation, discovered a rare, unusual alloy in the deep sea. Improper handling triggered a catastrophic incident.
Years later, the Lighthouse Federation announced the launch of the world's first NFT mecha. It also announced that it would enter Finan and station troops there, ostensibly to help the country achieve economic prosperity and freedom.
Kahn, a newly graduated mecha trainee, is assigned to the region for a nominal peacekeeping mission.
And so, the undercurrents stirring through the world begin to surface.
