Zero is the child of Rhinne, the Transcendence of Time. Born from her tears in an attempt to free her powers from the Black Mage, things do not go as planned once the Black Mage figured out her plan. The child was split in two, Alpha a male and Beta a female, and imprisoned in the Mirror World.
Only with their powers combined will Alpha and Beta be able to break free from Mirror World and ascend to be the next Transcendence of Time.
When the Black Mage attempted to seal the Transcendence of Time, Rhinne, she shed her tears to create a successor. However, the Black Mage was aware of this plan and Will, one of his commanders, was tasked with sealing off Zero in the Mirror World. To prevent Zero from reaching full power, Will also split him into two vessels and sealed one (Beta) away before taking the other (Alpha) to be brainwashed into their own goals.
Alpha, known as Nine at the time, was monitored by the Shadow Knights to keep him in his place, sending him off to fight off monsters known as Darklings. However, Zero grew increasingly suspicious of the Shadow Knights as they tried to keep him detained in Shadowvale, and his suspicions proved right when he finds a girl that looks exactly like him at the Umbra Temple. He later discovers a scroll detailing about the Black Mage's demise and his desire for power, which also details about how Rhinne was his target and shed tears to create a child.
The next day, the Shadow Knights make their move in destroying the Umbra Temple and deleting any traces of the girl, seemingly suspecting Nine's suspicious movements. Nine massacred all the Shadow Knights but was promptly defeated by Will, who inadvertently destroys the containment on Beta. The two halves of Zero reconnect, awakening their power and reverting the Umbra Temple to its original state.
Alpha and Beta are then informed by the temple's Record Keeper, Pietta, that the two are stuck in the Mirror World and, although they can leave to the Maple World, their power there is incomplete. Thus, the duo search for a way to break the chains holding them back in the Mirror World.
Instead of using Mana, Zero uses Time Force (TF). Time Force replenishes very quickly (approximately 5 points per second), allowing continuous use of skills.
Zero can battle monsters by Tagging or Assisting via Dual Combat. When using a different skill, Tagging allows Alpha or Beta to alternate, and the switched out character will continue to Assist for a short while, causing the switched out character to deal more damage.
Alpha and Beta do not share their HP and TF, meaning that if Alpha is running low on HP/TF, he can switch out with Beta, and vice versa. Potions are also not shared, and only affect the selected character. When switched out, the character on standby regenerates their HP and TF extremely fast.
Zero uses a unique evolving weapon that grows with them. Alpha wields the long sword Lazuli, while Beta wields the heavy sword Lapis. These weapons upgrade every 10 levels up to level 170.
After completing Chapter 1 of the main story, Lazuli and Lapis can only be enhanced through a special weapon UI accessible from the weapon button on the bottom left of the equipment inventory window.
Only 1 scroll or enhancement item is needed to upgrade both weapons. When the weapon evolves, you will have the option to carry over all enhancements or to reset the weapon. If the weapon is destroyed, the weapon can be repurchased without any enhancements.
By defeating enemies and completing dungeons in Mirror World, Zero will also accumulate WP (Weapon Point), which, with a small meso fee, can be used to reset and possible upgrade both Lazuli and Lapis’ potential.
Because Zero is unable to unequip their weapons, Lucky Item Scrolls have been added to turn Lazuli and Lapis into a piece for another equipment set. These scrolls will not change the stats of the weapons but will instead count the weapons towards the set bonus of the scroll used. Visit Cello in Zero’s Temple to obtain a few of these Lucky Item Scrolls.
As there are two characters that are able to be controlled, both Alpha and Beta wear the same cash items, though it is possible for them to wear both female and male garments accordingly at the same time, switching as they tag in and out.
Zero's skills are divided into two skill sets: one for Alpha and one for Beta. Both sets receive 3 SP every time they level, but their points cannot be distributed in the other tab (e.g. Alpha's SP cannot be added into Beta's skills, and vice versa). Zero only has one Job Advancement, and begins at level 100. Transcendent and shared skills are unlocked as Zero levels up, similar to Hyper Skills.
Alpha specializes in movement attacks and critical attacks, enabling him to attack much faster, while Beta specializes in defensive skills and heavy attacking, therefore attacking slower than Alpha skills.
