Early details on Devil Survivor 2 have surfaced from this week's Famitsu.

As mentioned here earlier, Devil Survivor 2 is being developed for the DS. It's not to be confused with 3DS title Devil Survivor Overclocked, which is a remake of the first Devil Survivor.

Mysterious invaders known as the "Septentrion" suddenly attack Japan one Sunday. They make their attacks once a day from then on. It's up to a band of 13 demon summoners to deal with the attackers within seven days.

Characters introduced in the magazine include:

Main Character
A third year student at a school in Tokyo. He gets caught up in all the happenings while on his way home from a test, and learns of his ability to summon demons.
Io
A student in the same grade as the main character. She's a gifted student who's admired by others.
Daichi
The main character's friend from childhood, and also a fellow student in the same grade. She's cheerful, bt doesn't think too deeply about things.
Gameplay will combine simulation with command battle elements. You'll be able to obtain new demons through demon auctions. One new system is the "Enishi System", which has something to do with your ties with your friends.

Staff includes Kenji Ito on sound. Like the original, the main character designs are from Durarara's Suzuhito Yasuda. Mohiro Kitou is doing the designs for the Septentrion invaders.

Devil Survivor 2 is due for DS release through Atlus this summer.

The game's setting includes major cities throughout Japan rather than just the Tokyo setting of the orgiinal.

The new "Enishi System" expresses the level of friendship you have with your fellow demon users. As this favor level increases, your allies will unlock new skills and more.

In an interview, director Shinjiro Takada said all gameplay systems are being improved. The staff is working to make players feel like all areas have been improved. He also said to expect a game that can be enjoyed repeatedly.

Regarding the three characters who were introduced in our previous article, the unnamed main character, Daichi and Io (who's a girl, not a guy as I previously wrote -- sorry!), the magazine reveals that all three suddenly gain the ability to use demons. They'll use this ability to fight against the invading Septentrion creatures.

The Septentrion invasion begins on a Sunday. They'll make another attack every day. You have seven days to stop them.

Based off the wording in the magazine, it seems that a different Septentrion creature will attack on each day of the week. The magzine introduces the Thursday attacker, who's named Alioth.
