To celebrate the completion of 'The Secret Palace Garden,' a story about a man's deep love with an AI girl, an early manuscript is being made public.

The manga 'Himitsu no Miyazono' (Secret Palace Garden ), which begins with Kanon, a lonely girl with no family or friends, being proposed to by Rion, a girl who calls herself an android, concluded its eight-part serialization in July 2025.
