La Mer and Artificial Flower City (English Ver.)

"Amazed, such an advanced civilization actually existed!"

-A Man's Memoir 01-
I was a poor archaeologist who spent most of my life researching the history that someone had hidden between the Western and New Worlds.
Everything in this memoir is true.
As usual, I was trying to return home on the old Tokyo Metro "unreadable" line, the last train of line 0 to "unreadable" station, and I felt some discomfort in the atmosphere inside the car, the interior, and the advertisements with letters that are not used anymore. Normally, the mere use of old-fashioned writing would have made an archaeologist's blood boil, but I was particularly tired that day, and as soon as I sat down, I fell asleep.
The next time I woke up, I couldn't believe my eyes, because the subway I was on was on the ground and the sun was shining through the windows.
And to my surprise, beyond the end of the line, there existed an abandoned city in a frenzy of colorful flowers.
