Transmigrating into Death Note: L and Light Reborn

Huihong transmigrates into Death Note and kills Light Yagami and L. The three of them enter an otherworldly instance together. After completing the Beastmen World and a deduction game, they are reborn in the real world. But L becomes a child again at Britain's Wammy's House, the orphanage for geniuses, and is adopted by Watari once more. Perhaps this time, Death Note will have a different ending.
