Monster Siren Records (MSR), one of the world's largest music publishers in the tenth century in Terra. From heavy metal bands to the idol industry, MSR artists are involved in all aspects of music. According to the latest statistics, MSR occupies more than 30% of the music market in Terra.

Monster Siren Records (MSR), commonly known as Monster Siren or Siren, is a record label in the world of Arknights. Based in Columbia with the famous rapper Emperor as one of its producers, many renowned musical acts from all backgrounds and genres across Terra are associated with MSR, earning them worldwide popularity and made them the most successful record label in Terra.

MSR is noted to employ some idiosyncratic marketing tactics, one of which is forming a "mystical rap/rock" band made up of five handsome Lupus.[1]

Associated artists




Hypergryph releases all songs made for Arknights under the Monster Siren Records flag. They also made an official MSR website where many Arknights songs, both from past and future events (in the Global server), are available for listening.

Later, Hypergryph (through a third party) made official accounts of Monster Siren Records in YouTube, YouTube Music, Spotify, and Apple Music. This is likely done to allow an easier access of their music to Arknights players outside of mainland China and in response to a YouTube account that monetized videos of Arknights music, taken from Bilibili without Hypergryph's permission, since taken down.[2]

Interestingly, although it is a common meme within the community that Hypergryph (through MSR) is a "music company," the music in Arknights appears to be exclusively composed by freelance composers external to the company itself, as will attest Operators' Themes, but also, surprisingly, the two in-game background music tracks that have been released on the label and thus received artist credit, Under Tides and Rewinding Breeze. Assuming that these two tracks are not an exception, this would mean Hypergryph does not produce any music in-home.
