Mecha Girl Era: Cold Beauty Seeks Night Upgrades — Episode 15

In a world ruled by mecha girls, Caesar Leat was nothing: F-rank scum ignored by all. Until he awakened the Upgrade System. A dying mecha girl was his first masterpiece: SSS-rank, born from scrap and sheer determination. Now he ascends, one upgrade at a time. But power doesn't go unnoticed. Mechanicus, the hidden elite pulling strings, thinks they're untouchable. They haven't met the boy who turns trash into legends. And his mecha girls? They would burn the world for him.
