Okay just the reveal about why Allen is in this world and the first place is worth the price of admission. And I cannot wait for that scene!
I am a little bit surprised at how when I read something on J-novel club, and then reread it later on as just a straight book, I'm not sure if the changes I see are just my memory being a tad bit faulty, or if things really are changing between versions. There were short stories in here that I had no memory of.
Also, the whole cartoon villain thing, really doesn't come off. The boss just comes across as cruel. If they're going to do the cartoon villain thing, they need to make it a little bit more obvious to the reader aside from our MC just saying, 'Oh he sounds like a cartoon villain.'
Aside from that, our smart MC does SmartThings and I am here for it.
Also, I have to wonder, how much further can he go? I mean what's he going to summon next, a god?
