"From the moment i received power, i gained only one dream. To be the best. To become the strongest Dragon Slayer ever existed in Pangaea, so i won't let you lot stand in my way."

Astraios (アストレーオス,Asutoreeosu) is a Dragon Slayer that utilizes Celestial Dragon Slayer Magic that was taught to him by his foster parent Cosmologia. He along with the other three dragon slayer children of the Dragon Hermits put a temporary ceasefire between them, all in order to help in the revival of the Magma Dragon Hephaestius so each may try to slay him and gain immense power.



Astraios has the appearance of a pale skinned teen with red eyes and white hair. He wears a white colored winter jacket with a fur collar and also has white long pants. He wears a black collar of magic nature that restrains his power. Normally, he has an apathetic and bored appearance but when in battle, his red eyes shine and his face becomes more twisted.

Astraios' appearance


When he was little, Astraios was emotionless, never feeling and hoping for anything. After Cosmologia saved and raised him, he became cheerful and a dreamer while he ended up loving to fight and due to that, he is mostly apathetic for most things and always seeks to fight with strong individuals to improve and strengthen himself. He loves Cosmologia immensely, to the point of training to the point of death in order to bring honor to her name against other dragon slayers and even join hands with the current ones in order to revive the supposed magma dragon and slay him to become stronger for her sake. He is childhood friends with Kranion Dragspilaion with whom he promised to fight when all the other dragon slayers, to whom he is bossy and cold towards,are dead and he will accomplish any goal he has set for himself like him. Despite his love for fighting and mission to eliminate the other dragon slayers, Astraios doesn't fight to kill and loses interest to those he defeats.

Celestial Dragon Slayer Magic

Celestial Dragon Slayer Magic  (天の滅竜魔法,Ten no Metsuryū Mahō) is a Caster ,Lost Magic ,an  Ancient Spell and a form of Dragon Slayer Magic that revolves around various cosmic forces.   This magic allows Astraios to transform the physiology of his body into that of a celestial dragon, being able to turn his body into light in order to avoid or commit attacks at terrifying speed. He can also utilize a golden light that is much stronger, hotter and holier than other forms of normal and dragon slayer forms of light magic, magic that he as a user of celestial dragon slayer magic can easily devour.Also, he can devour solar and lunar light while also being able to utilize them in his magic and being immune to them also.

This magic however isn't limited just to the utilization of light, being able to utilize forces such as gravity in their attacks in varying ways among other things, making this magic terrifyingly versatile, but gravity magic stronger than the user's own can undo and even affect the users.

The light of the celestial dragon is plasma hot, melting most things in its way and causing sever burns to those unlucky to face it. The celestial dragon's light is also holy in nature, being able to purify hordes of undead with its shine and harm demons and due to its status, it is often compared to the holiness and brilliance of Celestial Spirits which is proved to be true, with Astreus being able to siphon the magic energy of present celestial spirits which ends up sending them back to their world as Roxanne and her friends found out the hard way. Despite its power however, Astraios asa user of this magic can't affect with his light god slayers of the same element like Roxanne's Holy God Slayer Magic while said god slayers can easily devour and be immune to this magic's light.
