Characters
Time Line
One of the two goddesses who make up the world. She handles the timelines. Born inheriting the power of timelines from her mother, Gaia, she rules the world alongside her older sister, Gear.
She began to take the lead after Gaia went missing due to a certain incident in the past.
A mystic who is incredibly optimistic yet has a subtle, clever side. Since humans appeared recently, she has been observing them all day long.
Perhaps the way they build civilization looked so beautiful to her. And Gear disapproves of Line for this.
Time Gear
One of the two goddesses who make up the world. She handles life. Born inheriting the power to preserve life from her mother, Gaia, she rules the world alongside her younger sister, Line.
She lost her memories after Gaia went missing due to a certain incident in the past and cannot remember what happened.
She is usually serious but doesn't know what to do when flustered. More emotional than one might think. She changed recently when humans appeared.
She was an innocent girl who loved life in the past, but as humans appeared, her hair became short, she started hearing voices, and strange things began to grow on her arm. And now, Gear seeks to initialize this world.
Back to those days when humans did not exist.
Does not appear in the story, but is the root of all events.
Sourcebook
Intro
An ordinary, once ordinary world.
The world has perished.
The flow of the clock bestowed by Gaia, which governed the world, has become unstable. The clock, having lost synchronization with all people, will eventually reach -1 o'clock as it reverses. What you just saw is that final end.
I plan to swap timelines to prevent that destruction and save the world.
Immense energy is being released from the world's clock as it reverses toward -1 o'clock.
