Starting March 6th, separate story DLCs will be released weekly for all six of the sisters.  Firstly, One and Two’s DLC content will be available at the same time with the others following thereafter weekly.  Each story will focus more deeply on each of the sisters and their relationship with their respective Apostle.

Here’s the line up:

• One & Two’s DLCs:  March 6th
• Three’s DLC: March 13
• Four’s DLC: March 20
• Five’s DLC: March 27
• Zero’s DLC: April 3rd

Each DLC is 600 yen. From April, however, all sales taxes will be raised, so the price will then be 617 yen.  These extra story DLCs are only accessible after you have completed Branch A and have downloaded and installed the newest patch of the game.

One Vs. One (Brother)

Looks like there will be a scene in which the two twins fight within the Capital Tower.  Hmm…

Gabriella Fights along side the Twins

There’s a scene in which Gabriella will aid the twins in battle.

Memories of the Past

As you play and level up the sisters, it will unlock further “memories” of their past by which to further develop their character.

Utautai Mode

Each sister will of course have the ability to use their Utautai Mode in battle.

One and Gabriella

There will be a scene or two in One’s story in which you can ride on the back of her dragon companion, Gabriella.  At least in this point in time, she resembles a normal dragon rather than her chaotic form which Zero had to battle.  She also seems to have one heck of an attitude! “Shut up, porky.  I’m tired of you.”

Zero and Michael

Zero’s story will involve her past along with Michael as her dragon companion.

Gimme da Gold!!

It will be much easier to obtain a ton more gold in the new stages compared to the regular run through the game.  Be on the look out for those Gold soldiers that drop money when you attack them!!

Weapons of the Utautai

Each of the sisters will come with their own unique weapons that can be levelled up to unlock its Weapon Story.

LoV3

Zero & Mikhail will appear in the new version of the arcade card battle game “Lord of Vermilion III Ark-cell” from March 27th (tentative).  Zero’s card illustration is by DOD3 character designer Fujisaka Kimihiko and Mikhail is illustrated by Takagi Masafumi.

Starting with One, all of the sisters (including Zero) will have their extra DLC stories and battles released, starting next week Thursday, March 6th!!  Each sister’s DLC will be released separately every week for 600 yen.

It sounds as though each sister will also have a corresponding Weapon Story, too. Comparatively, as you level each sister up, it will unlock bits of their memory to better flesh-out their character and personality for the player. Hopefully this way, we can learn much more about them!!

According to Dengeki PlayStation Vol. 560, which was just published today (February 13th), we have learned that story DLCs involving all of the Utahime Sisters will soon be released.

Although he couldn’t reveal much at this time, in a brief interview with Producer Shiba Takamasa, we have learned that we will be able to play as each of the Utahime Sisters in a new story chapter for each of them.

He was asked if they would have another NicoNico Live Broadcast featuring this news, and he responded lively saying that he would like to do it again if the fans would be interested in watching, but only after the new DLC contents have been released.

So, hopefully these new DLCs will further develop the Utahime Sisters and give them a little more depth that the initial run through the game lacked.

EDIT:  Here’s the translation of the short interview with Shiba Takamasa.

DLCs are all set! The world of DOD3 is about to get much larger!

Dengeki: Previously in a live broadcast on NicoNico, you talked about future DLCs that would eventually become available. Could you tell us anything more about this?

Shiba: Yes. I came here simply to talk about this…although I can’t talk about the details just yet. I believe I also touched briefly on this in a previous broadcast on NicoNico, but we’re about ready to release some new Story DLCs. We’ll make an official announcement about this in a few days, so please hang in there until then. In any case, we’d like to add onto the game with these contents without making you wait too long to play with them. As far as what these contents will entail, you will be able to play as each of the Utautai sisters as they play the main role in a new story. These stories will fit into the beginning portion of the game, like a prequel. Please look forward to it!

Dengeki: Wow, that does sound pretty awesome!! Then, will you put on another NicoNico live broadcast before this release?

Shiba: I knew you would bring this up. There are a lot of factors–and courage–involved with doing a broadcast after a game’s release…… But if it’s for the gamers, I’ll try my best! In the end, I hope to announce more information about these extra contents soon! To all the fans, I really appreciate your support!

Dengeki: Thank you very much!
