In the world of Blue Archive, a halo (ヘイロー, halo) is a disk, ring or abstract pattern floating above a humanoid girl's head. Halos vary in colors, shapes, and designs, mostly referencing their respective students' personalities or general character theme. The halo's basic concept is easy to understand, yet mysteries around them still remain.

General Information

Seeing a halo is nearly as common as seeing gunfire happening in Kivotos. Halos act as a student's form of consciousness. If a student is unconscious (e.g. sleeping or knocked out), her halo will disappear temporarily and will return once she regains consciousness, which is denoted by her halo flickering.

Although it's generally believed and accepted by the students of Kivotos that halos belong to students as only they are seen with halos while other citizens aren't, it doesn't seem to be the case as other exceptions have been proven to exist with halos. Most notable are Tendou Alice and Tendou Kei, an android and an AI with halos even before she were enrolled as Millennium students. In her case, it's believed that they have a halo because they retain a connection to the Nameless Gods.

Another example is Decagrammaton's Prophets, giant robots/mecha roaming around Kivotos. In spite of being automatons, their connection to the mad god-machine has enabled them to gain halos of their own.

A few creatures, neither humanoids nor robots, also have halos of their own, such as Beatrice in her Ascended Form.

Design

Although halos are generally believed to normally represent students they belong to— whether they be by their personality, design or history —the halos' designs themselves can be quite abstract, making it hard to understand their connections with their respective students at first glance. The halos' designs can also vary from a plain, classic angelic single-colored two-dimensional shape to a highly-detailed three-dimensional form.

There are certain cases where halos have designs simple enough to make them hard to distinguish from another student's halo at first glance.

Yoshimi's Halo

Nonomi's Halo

Natsu's Halo

Ayane's Halo

As previously mentioned, some students have three-dimensional halos, standing in distinct contrast to the halos possessed by most of Kivotos' student body.

Abilities

While halos provide simple protection from bullets, they often have their limits in extended combat.

A student's halo shattering will result in her death.

Halos are the main reason why students are normally seen with firearms and other military-grade weaponry as they provide outstanding offensive and defensive capabilities, giving students more physical strength and allowing them to withstand small-arms fire and even tank shells; according to Shirasu Azusa, she states that an entire magazine from her rifle was enough to render Kirifuji Nagisa unconscious during the events of Volume 2 Chapter 2.

Halos also provide regenerative abilities, allowing scratches from bullets to heal by themselves, though heavier injuries (often sustained during extended, intense combat) still require medical treatment. Besides strength and regeneration, halos are speculated to also provide other superpowers such as super luck believed to be owned by Ichinose Asuna.

Like most things, the halos have a limit. Although it provides protective abilities, a halo can only shield well when given time. If a student receives massive continuous damage, her halo can shatter, resulting in her death. There are also some weapons that can allegedly destroy a halo if not bypass its protective nature, with said weapons, such as chemical weapons, usually being banned in Kivotos. Additionally, halos are not immune from natural disasters. For example, while a halo can absorb blunt damage, occurrences like infections, diseases, or falling from overly large heights can prove to be fatal.

Trivia

• There is currently only one student in the current timeline who is confirmed to have a shattered halo in the game— Yume from Abydos High School.
  • Anubis' halo was cracked when she appeared in Volume F. After she became playable however, her halo was restored while still retaining a dark color, indicating that her mental health has somewhat improved.
• Halos do not disappear when a enemy student or human mob is defeated in battle. Instead, the character model simply fades away. This is likely an oversight of the devs.
• According to implications from the director of Blue Archive in a 3rd Anniversary Q&A, the shape of a halo can generally be seen by others, but like small details seen on someone's face, they are generally given little, if any attention. Officially hired language interpreters misconstrued (from Korean to English) that Halos' shapes cannot be seen by others over the livestream or that they have no form, despite this being seen as false such as the Plum Blossom Garden background showing a toy shaped like Sunohara Shun's halo, or a Trinity Festival advertisement for Seraphim showing Mari's halo accurately recreated on a chalkboard, which was shown as an in game CG to promote an event alt announced a week after said Q&A in Japan.
