I read Hisaki Matsuura 'Fukano(Impossible)' (Kodansha.)The main character Hirooka joined in ROMS.
It is ostensibly 'The Repentant Old Men's Society.'
But actually means 'The Riot Operations for Mankind of a Salvation.'
The mystery becomes clear at the end chapter, 'Impossible.'
The gobo is ready at any time.
