Intro:
I was reincarnated from the dc world, with my regrets and fears, and it was I who indirectly harmed the Green Arrow Oliver...
At the moment of my death, so did my sword.
Oliver gave it to me himself. He told me to pass on the sword of King Arthur...
Since my rebirth, life has been very quiet, I have a new family, and a particularly good brother.
It wasn't until I was 11 years old that my brother Dane and I, who were traveling to ancient Egypt with my stepfather, had a lot of weird things happen in the temple of Ramses II.
The Fog giant hunted us down, but luckily we were saved by a big black dog who claimed to be Cold, who said he was from three years later and handed me a letter saying that I from three years later wrote to me from three years ago...
We follow the guidance of Tanus, accidentally into the world of Middle Earth, in the hobbit village, and accidentally gave birth to a boy...
It turned out his name was Edward.
Dane stole Bilbo the Hobbit's Ring, and his character changed from then on...
And I, upon my return to the real world, received an invitation to Hogwarts...
And frequently dream of a wizard who calls himself Merlin, he is constantly looking for a person -
King Arthur.
