Detective Conan: I Accidentally Picked Up a Little Girl and Made Her My Sister

A top intelligence analyst transmigrates to Beika Town and inherits the old library her parents left behind. She only wanted to live a quiet life, but one rainy night she finds a tea-haired girl. The girl is wary, precocious, and shrouded in mystery.

As they grow closer, she discovers that the timeline of this world is in disarray, and that the “APTX4869” the girl mentions is connected to her parents’ research.

As the Black Organization’s shadow silently draws near, the protagonist gradually uncovers the truth about this world.

Half in the dark, half in the light, with extraordinary intelligence. This time, the intelligence expert takes neither side. She stands only beside the small girl who refuses to let down her guard.

She uses bookshelves as shields and information as her blade.
