Kuroko Tetsuya, a deceased person, whose soul remains in the world due to unknown obsessions.
Having lost his memory of his life, the only way to make him disappear is to fulfill his wish.
So, what kind of story will he have with the five people from the Age of Miracles?
(↑↑↑↑ "Unheard Flower Name" means that the visual sense is correct. I just added the setting of the coded little angel in Unheard Flower Name to the Kuroko little angel QWQ)
