Zero to Hero: The Accidental Isekai Revolutionary

Zenjiro Iwanaga, a 27-year-old average Joe, was minding his own business when - poof! - he found himself whisked away to a fantastical world of skills and professions. Talk about a rude awakening! Three high school girls who were summoned alongside him hit the jackpot, receiving cool abilities and fancy job titles. But poor Zenjiro? Zilch. Nada. Nothing. The summoners, unimpressed by his apparent uselessness, decided to lock him up. Little did they know, our hero was secretly packing a mountain of skill points! Using his newfound points, Zenjiro pulled a Houdini and escaped his captors. Now he's living his best life, bringing modern conveniences to this medieval world. Imagine the looks on their faces when he whips out a smartphone or starts a karaoke party! While teaching his kidnappers a lesson or two, Zenjiro's busy creating his own personal paradise. Who needs a fancy title when you can introduce indoor plumbing to a castle?
