it was a super vr rpg anime which has a unique story and great combat scenes it also feels like SAO.
it doesn't feel like other isekai or game animes out there it is unique for its story and animation & Musictrack are great too. it has right amount of comic fun too.
but the pacing of the anime is a little slow compared to other animes out there.
the usage of skills and the game exp and other small details of the game is a little missing in my opinion if it explains the game mechanics in the anime little bit like sao then it would be a speck less masterpiece.
