Solid and a "realistic" take on an alternature universe situation. Character interactions are interesting, and the author treats the Thirteen Court Guard Squads as what they are supposed to be: a military force. Action is well-written. However, the pacing is sometimes a bit disjointed at times, and the limited third-person view is difficult to adjust to at the beginning. Despite that, I still greatly recommend this story. Author also uses English dubbed terms/spellings, like "Captain," "Reishi," or "Soul Reaper."
