Celestial (Aeri)

**Celestial** (天(てん)体(たい), *Tentai*?) is the Quirk used by Seiya Akaboshi.

## Description

Celestial grants the user the ability to user to use various properties of many astronomical objects, generate, and manipulate them. The properties of Celestial rely essentially on astronomical objects like the stars, meteors, comets, and the energy of the stars to release and incorporate into the user's own body. However, unlike many other Quirks, Celestial offers many supportive usages like creating weapons for friends to use and healing the wounds inflicted by humans, animals, and weapons alike.

Explicitly, it's sufficient enough to heal utmost injuries it's employed on, and to offset the effects of powerful venoms, and is competent to restore the body externally and internally including the patient's body stress and fatigue. Still, using similar powers is extremely tiring, as Seiya can not heal in successive renewals, nor can she use it to restore and heal herself.

Upon release of starlight, the light takes form as bright golden beams that can travel straight, bending along the way, or in a spiral, appearing similar to Nejire Hado's Wave Motion Quirk. The amount of starlight released can be adjusted by Seiya at will. In addition, her starlight can burn up to high temperatures just like the stars. Seiya has proven these temperatures to be extremely high, even higher than that of Dabi's flame, reaching temperatures of 2,087°C (3,789°F).

### Weaknesses

The release of starlight and creation of astronomical objects relies on the user's exposure to starlight during the night. Thus, the user must spends hours of their night out and about underneath the stars. Overusing Celestial and using up the night's exposure to starlight causes Celestial to use the own user's vitality to substitute, making it very exerting and tiring to the user. This is especially true when employing healing abilities, as it takes up two to three times the amount of stamina than it takes to create offensive attacks.

Celestial in it's raw form is extremely destructive and unpredictable, meaning the user must spend lots of time honing control over it's many niches and components.

## Usage

Seiya is a extremely skillful user of her powerful Quirk. Despite it's natural lack of agility, Seiya utilizes the energy of starlight in her own body to increase her own physical capabilities. By doing this, she can quickly get up close to her opponent allowing the blasts to hit the target sooner. The blasts of starlight have proven to be very effective against groups of villains and larger enemies that also lack in speed.

Seiya can control how much starlight she wants to output and can release it from her palms, elbows, knees, and feet. By continually releasing controller amounts from under her feet, Seiya is able to fly around with great control. Additionally, she can focus the energy under her feet with every step, giving her a quick boost with every step while traveling on land. She can easily defend herself and attack in many ways particularly from a longer range. Her overall fighting style and the way she handles her Quirk is very reminiscent of how Nejire utilizes her Wave Motion Quirk and Katsuki uses his Explosion Quirk.

Seiya can release very large and powerful blasts of light from her hands or legs as a offensive attack. In the same way, continually releasing this light from her feet increases her mobility, allowing herself to fly. Seiya can attack with her Quirk in close range combat, increasing her own physical capabilities, and adding more and power into her punches, kicks, and other close range attacks.

Seiya also uses her Quirk for many capturing, restraining, and supportive purposes. During the many events at Hosu City, she used her starlight to create a cage capable of momentarily keeping a Nomu at bay while Pro Heroes came to the scene. While taking the Provisional Hero License Exam, she was able of using her starlight to propel herself forward to save a couple about to be crushed by a fallen building. On the other hand, she could use her light to destroy things out of the way and a black hole to suck up things in the way, giving citizens a more secure path to safety. This all further shows Seiya's extensive control over her Quirk, as the damage she can create is large, she is able to control it to save others, not bringing them in any harm.

Activating her Quirk requires Seiya to drain her own exposure to starlight. She can suffer from fatigue if she overuses it as once her starlight storage is used, her body uses her stamina as substitute. Through intense training from a young age and her Quirk developing, this has allowed Seiya to build up more starlight energy in a short period of time and have high stamina, as well as being mostly resistant to stamina draining Quirks.

## Trivia

* Celestial stems from Seiya's father's Quirk, Brilliance; albeit Celestial has much more capabilities.
* Coelestis is named after the Atlas Coelestis, one of the more important and influential historical star atlas'.
