海帰線 [Kaikisen] [Tropic of the Sea]

In 1990, Satoshi Kon launched Kaikisen (also known as Tropic of the Sea) as a single-issue comic for Kōdansha, marking his only published manga work. The story explores a coastal community's supernatural encounter with a mythical sea creature, blending Kon's signature psychological depth with folkloric themes. Though brief, this early piece foreshadows the visual storytelling and atmospheric tension that would define his later acclaimed film career. It remains a fascinating artifact of a master storyteller's origins in sequential art.
