Tsuma, Shougakusei ni Naru.

Tsuma, Shougakusei ni Naru, known in English as If My Wife Becomes an Elementary School Student, was created by mangaka Yayuu Murata and debuted in the seinen magazine Weekly Manga Times in 2018. The series was conceived as a poignant exploration of grief and reincarnation, focusing on a man who loses his beloved wife and is shocked to encounter her soul reborn in the body of a ten-year-old girl. This high-concept premise challenges domestic norms and emotional boundaries, grounding its supernatural core in the heavy, lingering reality of long-term mourning.

Murata’s artistic approach emphasizes subtle character expressions and the quiet, melancholic atmosphere of a home left behind. The manga received critical attention for its gentle handling of a potentially jarring narrative, finding success through the empathy it builds between the reader and the protagonist as he navigates the complex social and psychological implications of his wife's return. The work's steady popularity eventually led to both a live-action television adaptation and an anime series, solidifying its place as a notable entry in the modern drama-manga genre.
