Mecha Era: I Can Contract Unlimited Mecha Girls

Synopsis

Blaze Xander was dumped by his girlfriend as soon as he entered the world of mecha girls. "An F-rank loser like you is not good enough for me, Blaze!" Right after his ex-girlfriend, Snow, said that, Blaze bound the system and awakened the SSS-rank talent, 'Infinite Recharge'. When Blaze controlled the SSS-grade mecha and stood at the pinnacle of the human race, Snow asked, "Blaze, can we go back to how things were?" Blaze looked at the charming SSS-rank mecha girls beside him and smiled faintly, "Sorry, you're not good enough for me, A-rank girl."
