Quasi-Spirits (準精霊, Jun Seirei?) are mysterious beings that live in the Neighboring World after the Spirits left for the real world. Unlike a genuine Spirit, they only possess a fragment of a Sephira Crystal. They make up the majority of the cast of Date A Live Fragment: Date A Bullet.


While living in the Neighboring World, a Quasi-Spirit's existence is powered by their Sephira fragment. If that crystal is damaged or removed, the Quasi-Spirit in question will immediately begin to fade away. The body of a Quasi-Spirit is actually formed of Reiryoku into an image acknowledged by their Sephira, including the physical injuries it sustained. If the Sephira believes that it has died, the Quasi-Spirit would die regardless of if they are already physically healed.[1]

In some cases, this belief-powered existence can result in impossible physiological traits, such as Rinemu who doesn't sweat even after a long walk because she believes "Idols don't sweat and don't need to go to the toilet", but sweats profusely when she realizes her career as idol had ended.[2] Another instance of this was when Rinemu's bust size changed due to her belief in the myth that drinking milk can make one's breasts grow larger.[3]

Additionally, the vast majority of Quasi-Spirits only have portions of their memories of their old lives as humans in the other world. However, the majority can't remember how they ended up lost in the Neighboring World to begin with. It is also not uncommon for a Quasi-Spirit to completely lose their memories and even their entire personality during their stay in the Neighboring World. Despite losing their memories though, Quasi-Spirits have knowledge about the real world. They also know they are Quasi-Spirits and have their own abilities, such as Astral Dresses and Unsigned Angels.

While living in the Neighboring World, the physical body is inconsequential compared to the real world due to the laws of the Neighboring World being completely different. What is essential for their survival is having a dream or aspirations for the future. A Quasi-Spirit that isn't attached to a strong desire will eventually completely fade away regardless of the condition of their Sephira fragment.[4]

In the Neighboring World, a Quasi-Spirit has territory. This territory acts as their protection. Inside this territory, a Quasi-Spirit can realize anything they want, although there are limitations. For instance, a Quasi-Spirit can only create things that suit the area they are located. A chalkboard or pencils can easily be created in a classroom setting due to easily blending in with the scenery, but something like a weapon would be harder due to naturally feeling out of place. There also needs to be adequate Reiryoku provided to fuel generating the creation. The ability to create this territory is also linked to the ability to realize their Angel and Astral Dress and thus makes them a full-fledged Quasi-Spirit, not a mere newborn Empty.[5]

A Quasi-Spirit can consume the Sephira fragment of other Quasi-Spirits to gain power. This is most often practiced in Malkuth, but other regions usually have an aversion to such an act of cannibalism.

When leaving for the real world, Quasi-Spirits must cast away their Reiryoku-based bodies for physical vessels made of flesh and blood. The process of physical incarnation can be extremely dangerous for those unfamiliar with human life. In Hibiki's situation, since she was never human to begin with, the procedure of creating lungs to breathe and forcing her heart to beat felt like torture and nearly led to her death if it wasn't for Sawa's lingering voice guiding her through the process. Afterward, if successful in entering the real world, the Quasi-Spirit becomes an ordinary human and loses all their powers. By the end of Date A Bullet, around 100 Quasi-Spirits underwent this process when migrating to the real world, leading to several of them to be taken under the care of Ratatoskr.[6]


Empty (エンプティ, Enputi?) is a state a Quasi-Spirit enters after losing the will to live. There are many girls who become Empty after falling into the Neighboring World because they lose all their memories, identity, and purpose as soon as they arrive.

An Empty is physically characterized by their white coloration, from hair to Astral Dress, and red eyes. Their energy is weak and, if left alone, they will disintegrate into light particles, which is commonly termed as "Lost."

Psychologically, becoming Empty is a horrifying experience, as they can feel their sense of self fade away. It comes in the form of lethargy and abandonment of everything in the world. According to Hibiki, who once fell into a near-terminal stage, Empty would even grow detached from their fear of death. There is discourse among Quasi-Spirits regarding the transformation into an Empty. Some believe becoming Empty rids a Quasi-Spirit of their suffering and pain while everything disappears. Retsumi Jugasaki mentioned that becoming Empty was like a disease that destroys the desire to live and decays the victim, and found it a more painful experience than Hibiki did as she didn't fall into such a serious stage. Despite this, Empty can still think. Their acceptance of death also allows them to fight without any restraint, abandoning taboos such as using their Unsigned Angels on others.

Empties are commonly regarded as insignificant. In regions where society develops, they are often used for menial jobs such as being servants or even slaves because of their obedient nature. The Empty under the White Queen are fanatical followers who would gladly sacrifice themselves for their beloved queen.

Unsigned Angels[]

Unsigned Angels (無銘天使, Mumei Tenshi?) are the personalized weapons of each individual Quasi-Spirit. While the appearance of each weapon might widely vary, the abilities usually revolve around the attribute of the Quasi-Spirits' genus. While similar to the Angels employed by the Spirits, an Unsigned Angel lacks the sheer authority and might possessed by a genuine Angel.

As a result of Unsigned Angels being comprised of Reiryoku, Quasi-Spirits can freely summon or dismiss their Unsigned Angel at will depending on how much Reiryoku they have left. According to Hibiki, an Unsigned Angel matches their respective Quasi-Spirit just like genetic fingerprints. While other people may pick up and use another Quasi-Spirit's Unsigned Angel as a weapon, only the true wielder can activate its full powers. Despite this, there are people like the White Queen, who are known to have armories storing Unsigned Angels stolen from other Quasi-Spirits.


Each Quasi-Spirit has a genus that is determined by the type of their fragment out of the ten Sephira Crystals. Their genus determines a rough archetype of their powers.

  • First genus (光): Light
  • Second genus (情報): Information
  • Third genus (影): Shadow
  • Fourth genus (氷): Ice
  • Fifth genus (炎): Fire
  • Sixth genus (封印): Sealing
  • Seventh genus (変化): Transformation
  • Eighth genus (風): Wind
  • Ninth genus (音): Sound
  • Tenth genus (物質): Substance/Material

According to Sheri, types 1, 4, 5, 8, 9, and 10 account for 80% of all Quasi Spirits. The other types are viewed as uncommon, with Type 3 being extremely rare at below 1%.


Dominions (支配者ドミニオン?) are the current rulers of the Neighboring World. Following the departure of the Spirits from the Neighboring World, each of the ten regions of the Neighboring World came to be under the rule of a Quasi-Spirit. As the leader, the Dominion stands at the top of the hierarchy of the region and determines how Sephira fragments are distributed in that region. Dominions also have the authority to reshape their region, although this is limited by how much control they have over their region. Dominions also don't necessarily have 100% control of their region.

The criteria to become a Dominion varies between regions. Chokmah is stated to rely on tradition; only Quasi-Spirits who meet the requirements can become Dominion. In Malkuth, strength and power are favored, with the strongest becoming Dominion, and in Yesod, Dominions are decided by popular vote.[7]

Due to Dominions that rule over their respective territories with an iron fist, Hibiki has noted that traveling between regions has now become much more difficult than it was before in the past.

After the conclusion of the war against the White Queen, Hibiki, Kirari, Mizuha, Carte, and Retsumi all decide to leave for the real world. Consequently, this led to a vacancy in the Dominion positions for their respective regions. Conversely, Maya, Ariadne, and Haraka decide to stay in the Neighboring World to help maintain it after becoming completely severed from the real world. Maya also appoints Yui to the role of Dominion of the Seventh Region Netzach, although Yui is still rather reluctant to accept the role. Upon Cistus' request, Maya grants the title of Dominion to the former Kurumi clone as well.

  1. Keter: Currently None
  2. Chokmah: Maya Yukishiro
