IKUsei

Based on the adult visual novel by Msize, IKUsei follows Masaki Fujiwara as he struggles against an overwhelming and taboo attraction to his own mother. Fully aware that his desires are abnormal, Masaki finds himself unable to suppress them. The burden of this secret isolates him, leaving him unable to confide even in his close childhood friend. As his frustration mounts and his self-control finally shatters, he becomes consumed by his mother's beauty—from her voluptuous figure to her gentle voice—until he impulsively acts on his urges and touches her. Instead of the rejection he anticipates, Mitsue's reaction takes a startling turn. Though she verbally chastises him for lusting after his mother, her physical response torments him in ways that awaken a deep, unexpected sense of elation within him. Unbeknownst to Masaki, his mother harbors a similar hidden awakening, revealing herself to be a masochist despite having no blood relation to him. Caught between his newly discovered dynamic with his stepmother and his childhood friend, who possesses a commanding, queenly temperament, Masaki is forced to confront which path his true nature will ultimately choose.
