I've gotten reborn into a mecha. Furthermore, I'm the type with just a metallic shell without an actual body piloting it.But I still manage to secretly help my pilot many times with my powerful battle intent so that we can save the world, which has gotten infiltrated by monsters.I'm supposed to be hailed as a hero, but instead, I'm used as a trashed mecha that's meant to serve as a practice mecha for newbie pilots. This is all thanks to the fact that I've gotten my core damaged during my last battle with a monster, which has caused my functionality to drop rapidly.But just as I'm thinking that I should spend the remainder of my years in peace, little do I know that it's only the start of my nightmare.
