大雪海のカイナ [Ōyukiumi no Kaina]

In this concise 2022–2024 sci-fi fantasy series from Kōdansha, writer Tsutomu Nihei and illustrator Itoe Takemoto reteam for a stark, four-issue saga set on a frozen world where humanity clings to life atop a vast ocean of snow. The story follows Kaina, a young boy from a dwindling treetop village, as his encounter with a mysterious girl from a distant, technologically advanced kingdom sparks a journey that could reshape their dying planet.
