魔天楼―The City In the Deep [Matenrow: The City In the Deep]

A haunting, surrealist horror manga from 1994 that remains a singular, unfinished work from Seishinsha. Centered on a mysterious, shifting tower-city that materializes in the deep sea, the single issue is defined by the atmospheric, dreamlike art of creator ぴゅあ. Its enduring cult status lies in its stark, silent storytelling and a premise that feels like a fragment of an epic nightmare, never to be completed.
