What happened

Okabe deliberately leaves the year in which he is destined to die, allowing history to continue toward its required conditions. The rescue closes STEINS;GATE 0 by carrying forward what was learned across countless failed world lines.

Cause

Both principal endings have been established, and the video D-Mail and time-machine coordinates are ready.

Action / decision

Okabe sets out to find Mayuri and Suzuha and reaches their era with spare batteries sufficient for the return trip.

Consequence

STEINS;GATE 0's true ending is completed; its chain of information reconnects to the original game's final chapter and makes the Steins Gate world line reachable.

Version differences

The official Traditional Chinese ending title is cross-checked against a Taiwanese guide; the game and anime frame the rescue differently.
