About the series
A warm, funny, and startlingly honest series from Kadokawa, Seiri-chan (2018–2020) personifies menstruation as a tiny, persistent character who visits the protagonist each month. Created by Ken Koyama, this seven-issue comic turns a universal but often taboo experience into relatable, slice-of-life comedy, exploring the physical and emotional chaos that comes with the monthly visitor. Its matter-of-fact, empathetic approach made it a quietly groundbreaking work in normalizing conversations around women's health in manga.
