Monster-Colored Island

Without a single friend, middle schooler Chigawa Kon lives on a small island and laments that she hasn't "fallen in love" yet, unlike her classmates. She often plays by "the Hole", a cave near the sea where a man-eating monster lives, according to folk tales. One day, as she meets with another girl who accidentally drops her smartphone in the sea, they fall from a cliff together but miraculously survive. It turns out Furuka is also all alone. Half chapters (10/12 pages) are published in Young Dragon Age (formerly Bessatsu Dragon Age/Dragon Age Extra), every 2 months, if the series isn't skipped. Update 08/2026: the author gave a heads up and now, full chapters will be published every 4 months.
