Aiko no Maa-chan

Finished

あいこのまーちゃん

Aiko is a schoolgirl who feels left out when she discovers that all her friends have already had their first menstruation, while she hasn't. Frustrated, she punches herself in the uterus, which awakens Maa-chan, her anthropomorphic vagina. Maa-chan introduces herself as a lifelong companion who will guide Aiko through the challenges of growing up.

With Maa-chan's help, Aiko begins her journey into adulthood, navigating the physical and emotional changes that come with puberty. The story follows their unique bond as Aiko learns to accept and understand her own body.
