Amyzades's manga / #Preview?(1)

Gray(Lujun Kazekaoru)

Ongoing | Lujun Kazekaoru | 2015 released

Really silly, bad history, but the art is beautiful. People say it's a 'Prologue', a 'Preview' of something else, it's really ongoing (not complete), but stopped being updated/translated a long time ago (2017).
