Kaito returned one final time to the place once called Before the First Light.
The sphere of the First Architects appeared faintly.
Not as summons.
As greeting.
No lessons were exchanged.
No requests made.
The ternary structure was stable.
The experiment of evolution had succeeded.
The sphere pulsed softly.
Gratitude.
Kaito bowed his head slightly.
Then he left.
And this time—
The corridor did not remain open.
It did not need to.
