Pregnant Ninja by Moonlight

In the shadows of a moonlit night, a young ninja named Kaito finds himself in an unexpected predicament. After a mission goes awry, he encounters a mysterious woman named Ayame, who is also a ninja from a rival clan. Their brief but intense encounter leaves Kaito with a strange mark on his body, one that binds him to Ayame in ways he never imagined.

As Kaito tries to return to his normal life, he discovers that the mark has a peculiar effect: it causes him to experience the physical sensations of pregnancy. Confused and desperate, he seeks answers from Ayame, who reveals that the mark is a result of a forbidden jutsu she used during their fight. Now, Kaito must navigate the challenges of his new condition while dealing with the ongoing conflict between their clans. The situation grows more complicated as Ayame herself becomes entangled in the consequences of her own magic, forcing them to work together to find a way to break the curse before it's too late.
