Astro is Athena's brother- Cryo vision wielder, uses a claymore, a 34 year old man, mostly seen in the Aristocratic city of Fontaine, very indulged in caffeine. He's your typical guard who's always on duty 24/7. (After a long separation- he doesn't see his sister much anymore...Unless if Athena plans to go to fontaine and visit her brother nonetheless) Very rude guy btw...
