This is the story before everything started.
"Merlin, would you like to hear me tell you a story?
My story before I met you. "
"I had a few friends, very good friends.
Later they left one by one.
Will never come back. "
Those guys...
A fallen angel leader who was a caged bird but yearned for the sky and died together with the flying species.
A fallen angel leader from the far north, who finally pulled the Neptune type, turned into chains and sank into the deep sea.
One completely assimilated with mana and made himself into the final technique to seal the fallen angel.
A woman who could see the distant future and jumped off the cliff after the war to meet the ideal country she saw——
And that creature (me) named Abyss, after the last friend left, began to become a fallen angel because of his excessive obsession, and his existence was erased by Abyss (me) himself.
All five of them... Are fools.
"Except for Abyss (me), the existence of the four of them was erased by the world (father), and no human being except me remembers that they ever existed.
I never thought that I would see them one day.
They all have a new life of their own, no longer being used as pawns by anyone. "
I should be happy...
But why do you cry?
This is a spin-off to "Has Merlin Worked Overtime Today", somewhat similar to a personal prequel to 'Abyss'.
The protagonist is not 'human'.
