People cross lines that cannot be crossed, or break off connections that can't be rejoined. What's striking is how you leave open multiple possibilities rather than resolving conundrums in the manner of genre fiction. It's as if you simultaneously affirmed and denied the existence of fantastic realms. Tell me when you find out. Some characters in my books do find their own doors.
Nobody knows whether that door is fortunate or ominous before opening it.
The most important thing is to realize that the door exists. That's the way we are. Contradiction and ambiguity are our two best, most honest friends. Without them we'd be totally lost. You operate outside the mainstream of Japanese literary culture, and at the same time your books are widely popular.
