Detective Conan: My Wife Is Yumi Miyamoto

After being born into the world of Detective Conan and living there for eighteen years, Uehara Tsukasa always thought he was just an ordinary, lucky guy. Then, just as his relationship with Yumi Miyamoto settled down, memories of his past life came roaring back. Along with them came the activation of the Romance and Self-Preservation System of the Myriad Worlds: it automatically draws top-tier rewards from the Myriad Worlds every day, with no cost or restrictions.

Peak charisma, an eternal physique, maxed-out cultivation techniques... On a stage where the timeline is forever chaotic and nobody ever ages, Uehara Tsukasa decides to stop being a mere spectator. Faced with lurking darkness and a steady stream of cases, he wields the power of the Myriad Worlds and resolves to weave a legend of his own. Starting at Yumi Miyamoto's breakfast table, he will travel to every corner of this world, gathering every star that shines in the river of fate into his eternal tapestry.
