Scalpel, Phantom Pain, and Nexus

Good news: He transmigrated to the world of Ultraman and found Asuka in an alley, where she became his live-in roommate.

Bad news: This is the grim, gory world of Nexus, where Space Beasts that eat people roam the streets, memory police erase witnesses, and the powers behind the scenes are always trying to strap the Deunamist to an operating table and dissect them for research!

As an experimental subject abandoned six years ago, Ling Lei only wanted to look after his little clinic, pamper his own tsundere young lady, and live out the rest of his life in peace. Until Ren Senju's final battle ended, and the light that should have chosen Nagi Saijo instead fell into the hands of this pilot who had lost her Unit Two.

When the light of Noah that had lain dormant within Ling Lei for years began to beat once more, Asuka drew the Evoltruster. With a scalpel in her left hand and the light of evolution in her right, she also pulled Jun Himeya and Ren Senju back from the brink of death, even though they were supposed to have left the stage.

But where will the unknown story after Ren Senju's arc lead? What secrets lie buried in the depths of Ling Lei's erased memories?

"Hey, you idiot quack, what are we having for dinner after we take down this monster?"

"Whatever you want. But before dinner, I need to clear out that bunch of annoying flies outside."

P.S. This fanfic is based on scrapped ideas from the original work, including but not limited to Team Two and Dark Lucifer. Aside from the beginning and the ending, it's mostly original.
