テガミバチ [Tegami Bachi]

In the dark, perpetual twilight of Amberground, a young Letter Bee named Lag Seeing risks his life to deliver the light of human emotion across a land where the sun never shines. Written and illustrated by Hiroyuki Asada, this Shueisha series from 2007 to 2016 blends steampunk adventure with heartfelt drama, following Lag and his companions as they navigate a world where letters are precious cargo and the monstrous Gaichuu threaten every journey. Its 20-issue run earned a devoted following for its lush, melancholic art and its tender exploration of connection in a world of isolation.
