Operation Arc-Light

Operation Arc-Light (misinterpreted as Operation Aquila in the official translation of the Steins;Gate 0 visual novel) is, on some Beta World Lines, an operation executed by Mayuri Shiina and Suzuha to bring Rintaro Okabe to his senses following his failed attempt at saving Kurisu Makise, all in order to reach the Steins Gate World Line. This plan would be backed up by Operation Skuld; if only one or none of the operations had succeeded, the path to Steins Gate would not have shown itself to Okabe.

In the Drama CD Arc Light of the Point at Infinity the plan was devised by Mayuri herself, while in the Steins;Gate 0 visual novel it was relayed to her and Suzuha by a Itaru Hashida from 2025.

Namesake
The name "Arc-light" comes from how the star Vega is supposedly described outside of Japan, namely "Arc-light of the sky". Furthermore, the star Vega can also be called Orihime in Japan. Orihime is a girl in the Japanese version of an old folk tale who had a lover named Hikoboshi, but to their dismay they could only meet once a year; a specific day which is celebrated as Tanabata in Japan. In the Beta Attractor Field, Mayuri Shiina wanted to be the "Orihime" of Rintaro Okabe, who she in turn called her "Hikoboshi".
