I must have missed the part where it's mentioned how the MC got isekai'd into an MMORPG.
Come on, I can deal with levels and a spell that lets you see a status window, but monster loot tagging? You reach a point where you can't introduce any further video game mechanics if you want it to be a 'real' fantasy world and not some VRMMORPG isekai. Fucking japs, I swear.
