It was only when he blocked the fatal sword for me that I understood "fear".
Afraid that his soul will be scattered, afraid that he will no longer remember me, afraid that the world will not be able to tolerate even a trace of his soul.
So I took him with amnesia through the starfall of the Magic Continent, through the smoke of the battlefield of World War II, through the wreckage of the interstellar fleet, and through the wind and sand of the apocalyptic wasteland.
The world calls me crazy, but they don't understand - I tore apart time and space and reversed destiny, just to let my little frog demon remember me again. (Starting from Chapter 1, see how I take him with amnesia through all the world lines to find the complete him)
