Hell Mode volumes 1-3

Protagonist is obsessed with difficult video games. He's reincarnated into another world where he is the only person in "Hell Mode", whereby it becomes 100x more difficult for him to level up - but in exchange there's no limit to his growth, and he's granted the unique class of Summoner.

I put off this series for a while because I figured the protagonist would annoy me. And he does, especially in volume 1 where he keeps poking fun at LN tropes or explaining how his pro gamer skills mean he's perfectly equipped for a given situation. (And for many other reasons in later volumes)

Still, protagonist aside I am enjoying the series overall. It's your usual fantasy world of monsters and magic, guilds and classes, a demon lord to defeat, etc. Nothing particularly stand-out, but an enjoyable read nonetheless.
