Author knows their stuffs, better than other MMORPG with PVP out there by actually integrating accurately in game mechanisms and terminologies.
The protagonist has a very chill, hot-blooded and competitive battle maniac likeable shounen protagonist personablity (kinda like Goku & Naruto without the perversion). Cast is chill, the twins are funny (Freya is adorable and Frey is a very good dork friend), the drawings are good, there are also a big variety of character subtitles.
Characters are portrayed pretty relatable way if you know the gist of online Internet toxicity but take stride of it as casual fun.
The events are fun and light hearted, there's not an ounce of irritable drama (kinda reminds me the vibes of MMORPG shut in lady who played as a guy; but with a hot headed teenager protagonist instead). No dating shit, no stupid drama, just people looking to have a good time farming challenging mobs, speed running to the top, testing their builds and skills, and focus on the wonders and excitement of exploring new areas.
There's also no weird romance vibes that might make the situation awkward or uncomfy due to the GB. The GB doesn't even matter much just pretty much exists to justify a cute skin for the protagonist (maybe it's more relatable to create a GB girl for the audience than a hot blooded audience since GB is all the rage).
No harem vibes but there's a decent amount of female characters "orbiting" but the ratio of male female cast seems to be 1:1 so far.
It's fun if you enjoy spectating small scale battles.
Tldr: Super chill campy dorky series but with decent action and a love letter to PVP.
