Septentriones

Alioth, one of the Septentriones.

The Septentriones (セプテントリオン, seputentorion) in Shin Megami Tensei: Devil Survivor 2 are mysterious invaders that arrive in Japan and begin attacking the country on a Sunday.

Appearances

Devil Survivor 2

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.

Naming

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)	Star of Greedy Wolf
Merak	巨門星 (Kyomon Sei)	Star of Gigantic Gate
Phecda	祿存星 (Rokuzon Sei)	Star of Wealth Saving
Megrez	文曲星 (Bunkyoku Sei)	Star of Scholarship
Alioth	廉貞星 (Renjō Sei)	Star of Incorrupt and Chaste
Mizar	武曲星 (Bukyoku Sei)	Star of Martialism
Benetnasch	破軍星 (Hagun Sei)	Star of Crush Army
Polaris	北極星 (Hokkyoku Sei)*	Star of North Pole
Alcor	輔星 (Ho Sei)	Star of Auxiliary

* 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).

Members

• 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.
• Phecda: While immune to almost everything while whole, it is also capable of splitting itself into two, while sacrificing its nigh-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: A god-like entity and mastermind of the Septentrione invasion. It rules multiple universes from the Heavenly Throne, and thus is able to control their fates.

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.

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

Trivia

• Each member of the Septentriones is named after one of the stars that make up the Big Dipper constellation. Excepting Alcor, they also appear in the story according to their Bayer designation, starting with Dubhe (alpha) and ending with Benetnash (eta)
• 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.
