Alioth, one of the Septentriones.

The Septentriones (セプテントリオン, Seputentorion)? are alien antagonists in Devil Survivor 2.



Devil Survivor 2Edit

Mysterious invaders that arrive in Japan and begin attacking the country on a Sunday.The Septentriones show up at least once a day and there is a time limit of seven days to defeat them. They have been employed by Polaris to aid in its destruction and recreation of the world. The main targets of their attacks are the radio towers in Tokyo, Nagoya, and Osaka, as these towers are actually projecting a barrier that has been preventing their respective regions from disintegrating into the Void. Once all Septentriones have been defeated, the path to Polaris will open, allowing humanity to seek an audience with it.


In the Japanese version, the race names ("Star") for the Septentriones differ each other which correspond to their respective ancient Chinese names.

Enemy JP race (romaji) Literal meaning
Dubhe 貪狼星 (Tanrō Sei)Greedy Wolf Star
Merak 巨門星 (Kyomon Sei)Gigantic Gate Star
Phecda 祿存星 (Rokuzon Sei)Wealth Saving Star
Megrez 文曲星 (Bunkyoku Sei)Scholarly Star
Alioth 廉貞星 (Renjō Sei)Star of Integrity and Chastity
Mizar 武曲星 (Bukyoku Sei)Star of Martialism
Benetnasch 破軍星 (Hagun Sei)Army-Crushing Star
Alcor 輔星 (Ho Sei)Auxiliary Star
Polaris 北極星 (Hokkyoku Sei)*Star of North Pole
* Not to be confused with Hokutosei (北斗星), the Taoist name for the Big Dipper.

Except for Polaris, all subordinates directly under the Septentriones (not the generic demons which can be summoned by the player) are given the same Japanese race title as their parents but without the suffix "Sei" (star).


  • Dubhe: The pink mass on its top can expand and explode.
  • Merak: It is capable of creating small, red sub-units that explode upon reaching their destination. It can also fire an icy beam with a large range.
  • Phecda: While immune to almost everything while whole, it is also capable of splitting itself into two, while sacrificing its high-invulnerability.
  • Megrez: It appears from the Pacific Ocean and launches the needles that are on its body at the various areas of Japan. Those needles are capable of moving on their own and can cause earthquakes.
  • Alioth: It flies far above the attack range of the party's demons while dropping neurotoxins at its targets below.
  • Mizar: It is made up of smaller versions of itself that grow rapidly. If any grown clones are attacked, they too can split into smaller Mizar clones.
  • Benetnasch: It can split itself into four pieces, control the minds of team leaders so they cannot injure it, and disable any attempt to summon demons. It can also replicate the abilities of the other Septentriones to a limited degree.
  • Alcor: Appears on the last day in order to open the path to Polaris.
  • Polaris: Not a Septentrione, but a god-like entity - and Administrator - that rules from the Heavenly Throne in the Akasha Stratum and the mastermind behind the invasion.

Each member, barring Polaris, appears for battle on a separate day, and has its own signature attack. Those signature attacks also correspond to each of the attacking elements in Devil Survivor 2. Their order of appearance also corresponds with their Bayer designation in the Big Dipper constellation.

Name Designation Appears Signature Attack Element
Dubhe Alpha Sunday Binary Fire Fire
Merak Beta Monday Circumpolarity Ice
Phecda Gamma Tuesday Dark Thunder Electricity
Megrez Delta Wednesday Ruinous Wind Force
Alioth Epsilon Thursday Marked Wing Curse
Mizar Zeta Friday Star Pressure Physical
Benetnasch Eta Saturday Alkaid Almighty
Alcor 80 Sunday Ominous Star --


  • The eight stars in the Devil Survivor 2 title logo points to the Septentriones needed to beat in order to reach Polaris. Seven stars under the logo points to Dubhe to Benetnasch, while the last one above the 'D' in Devil title is Polaris due to its positioning relative to the Big Dipper constellation.
  • The Septentriones are written as "Septentrions" in the original Japanese.
  • In the game the larger Septentriones like Merak and Megrez were scaled down to have them fit, with the anime showing how big they truly are.
  • The Septentriones bear some resemblance to the Angels of Neon Genesis Evangelion, in that they appear singularly, apparently destroy for the sheer sake of it and are named in a similar manner (in this case stars as opposed to angels).
    • They share further similarity with the series, as they were designed by Mohiro Kitoh, the comic artist who designed the third angel in Rebirth of Evangelion 2.0
