Megumi Chigasaki sports short, spiky orange hair with curtained bangs swept to one side and violet tareme-shaped eyes. Her slim, pale teenage frame stands 158 cm tall, measuring 82-56-85 cm (bust-waist-hips). Born on November 11, she typically wears casual outfits like crop tops, tank tops, shorts, trousers, belts, and headbands, occasionally donning occupational costumes such as a maid’s apron-dress or school uniform.

Initially homeless, she lives alone in a shipwreck off Shizuoka’s coast. Her energetic, confrontational nature surfaces immediately—she clashes with protagonist Youhei Hozumi during their first encounter around May 28. She frequents the local shopping district street and shoreline near her makeshift home.

Later, she peripherally assists a struggling band at Shinjyou music studio, though she isn’t a core musician, vocalist, or instrumentalist. Her background and motivations for joining remain unspecified, yet her interactions imply gradual community integration.

Her narrative presence is confined to the original visual novel, with no documented development, backstory expansion, or appearances in other media adaptations like the non-hentai OVA.
