Casey Baseel of SoraNews24 stumbled upon the gem, which showcases Seiri-chan meeting various women for their monthly visit. Each chapter contains humorous interactions as Seiri-chan tries to help with personal crises.

Some highlights include Seiri-chan comforting a woman after a salacious night of casual sex. Seiri-chan’s visit is greeting with relief, highlighting that the night of passion didn’t lead to an unwanted pregnancy.


Not everything is serious – at one point Seiri-chan gives a callous man a “menstrual punch” and injects him with a drug so that he can experience the wonders of having a period.
