Unable to fit into society, Grape and Apple get by running a sketchy handyman business, until they take on a bizarre new job: raising Wrench, a robot who has somehow developed human emotions, as a "normal" boy! Now, the curtain rises on a chaotic new life of firsts as this unlikely trio starts living under one roof!!!

In a world where kaiju attacks are an everyday occurence, our fiercely otaku protagonist Haruto ends up being chosen as the candidate for the "Giant Anti-Kaiju Unit Vigness", despite having absolutely no will to fight them. However, when the things he likes are at stake, he'll do whatever it takes to protect them--even if it means transforming into Vigness Type-3.
