electrical energy, taken from the entire Japanese archipelago. The naming is the result of a specific request from the series' director, Hideaki Anno, who asked to include something related to the name Yashima during the production. In "Rei II" scientific concepts are used as well. During Operation Yashima, for example, Eva-01 uses the Positron Sniper Rifle, which draws its power from positron acceleration, generating a bright beam of photons. The Magi System, a biological supercomputer composed of three computers that rule Nerv and Tokyo-3, is also mentioned for the first time in the episode. The Magi System is a democratic and rational system similar to the concept of artificial intelligence. Its name originates from the Biblical Magi who came from the East mentioned in the Gospel of Matthew, traditionally named Melchior, Balthazar, and Gaspar. According to the official Evangelion film books, like the three astrologers from whom it takes its name, the supercomputer is composed of three independent calculators that to solve any kind of problem consult each other and make a decision by majority.

Shinji bursts into tears, and Rei says she doesn't know what to do at times like that; Shinji advises her to smile. Rei overlays Shinji's and Gendo's faces and smiles, and it is not clear if she is able to understand Shinji's feelings in the scene. Writer Dani Cavallaro described it as "an ambiguous Mona Lisa smile". For critic Manabu Tsuribe, the show reaches its climax at the smile scene, and "as a story of 'growth and independence of a boy'—like a Bildungsroman—ended there once. Evangelion as a story has stopped there". Assistant director Masayuki gave a similar interpretation. Evangelion Chronicle magazine noted how the tactical realism of Operation Yashima was a rarity for anime at the time. The magazine linked the realism of the strategy to the Gulf War, the images of which had
