This manga is like an 8 year old playing pretend mixed with a 16 year old's daydreams while going through puberty. Tiddies and sex and explosions and basically zero coherence between events and power scaling but mechs are cool yknow.
I can't wait for our genius hero to give them a crash course on semiconductor and circuit theory before starting them up with widespread programming and electrical equipment.... because he surely knows that anything he provides will be useless shortly after he's gone for good one day otherwise...
Honestly, while for the most part this manga is pretty trashy, sometimes it's nice to read something with an edgy asshole who actually makes the right decision in these scenarios lmao
