"Additional Memory" is an original song by Jin featuring Hatsune Miku.

The song is part of the Kagerou Project, with its focus on, as she commits suicide and becomes trapped in the Daze. It can be said that the song is the parallel version of Ayano no Koufuku Riron, both surrounding the event of her death; the overall atmospheres of the two songs seems to represent the conflicting emotions on the decision. While the former speaks about Ayano's resolve to save her family and friends, the latter mainly expresses her regrets. She laments to having not confessed her love to, and grieves that she can never be with him again.

The song will be released in Jin's upcoming album, Mekakucity Reload.
