''Itsuwari no yume ni hikari sagashitemo Shinjitsu ni wa tadoritsukanai to Wakatteiru kara''

''Sono maboroshi wa kanashiku dakedo yasashiku kagayaku Kokoro ni yadoru tashika na ishiki wo sagashita Tatta hitotsu no ashita wo yume mitai ni mo kanjite Kono chikara ga ima jounetsu wo hanatta''

Trivia

 * This is one of the two openings in Toaru Kagaku no Railgun anime adaptation in general to not include Kamijou Touma, alongside future gazer.
 * The opening video contains the most Level 5s in any opening video of the Toaru Majutsu no Index animated adaptations alongside sister's noise.
 * Despite Mikoto seen battling the Doppelganger's fake copies in the opening, in actuality, she only cut the threads that the fake copies generate and does not fight them. The ones that she fought however are the ones at the airship and have a different appearance than the fake copies.
