First of all, this manga isn't a direct adaptation of PS3 RPG Ar nosurge. The story in the manga are different and takes place before the game, so essentially it's a prequel. It's hard to recommend this manga to people who doesn't have any experience with the series since this manga will assume that the reader are already familiar with the characters and events that happens in the PS Vita game Ciel nosurge, another game from the same series that never got released in english officially. However if you're a fan of EXA_PICO universe or Surge Concerto in particular then you should definitely check out this manga, it'sa fun read with pretty good art and the story definitely adds more lore and world-building into the series.
