Phantasy Star Online 2: Episode Oracle (Original Japanese Version)

Out of nowhere, all ARKS are ordered to return to the fleet. What's more, a certain rumor has spread through the panicking ranks of ARKS. Xion appears before a troubled Ash and says this is the moment they have been waiting for.

Guided by Xion, Ash and Matoi head towards the core of the Mothership but find that their way is blocked by the strongest defenders of ARKS.

Gaining the cooperation of the Council of Six, Ash and Matoi rush onwards to save Xion. But before they can reach her, standing in their way is...

Fueled by rage, Luther unleashes the form of Dark Falz [Luther] and attacks Ash. To stand a chance against [Luther]'s overwhelming power, ARKS must unite and confront him together. How will the battle end?

Ash learns from Xiao that all data regarding Matoi and a certain incident ten years ago was completely erased from Xion's memories. Ash resolves to go against the time stream to uncover the truth, but waiting for him there is…

Driven by a thirst for revenge, [Apprentice] assaults an ARKS Ship. With Klariskrays the Second separated from Clarissa, [Apprentice] employs despicable methods to corner her. Ash rushes to her side in hopes of saving her, but…

Ash returns after seeing what fate befalls Klariskrays the Second with his own eyes. Meanwhile, following his encounter with [Apprentice], Afin attempts an investigation of his own to learn more about Dark Falz.

A Falspawn attack on Lillipa prompts an emergency call to arms. Thinking that [Apprentice] may appear, Ash and friends head there at once. While helping Afin search for Euclyta, Melfonseana struggles with her emotions when suddenly reunited with [Elder].

Ash and Matoi have a surprise run in with Sarah who gets frazzled and scurries away at the sight of Matoi. While trying to chase her down, Ash encounters Maria and learns about the "sin" which heavily weighs on Sarah's shoulders.

Ash finally discovers the true identity of the masked Dark Falz who stabbed Matoi. Confronted with the fate of Matoi as well as his own, Ash broods over how he might save her while making his way to visit a certain someone.

Trapped within [Gemini], Ash and Matoi once again meet Luther the Fallen who has become a part of [Gemini]. There he reveals the truth behind the void in Ash's memories.

The [Profound Darkness] has revived. Desperate to defeat it whatever the cost, Regius and Xiao make a heartless decision. However, Ash holds Matoi too dearly to sit back and do nothing.

The final battle begins. As the entirety of ARKS unites as one in hopes of saving Matoi, Ash confronts her now that she's finally become the [Profound Darkness].
