Astrael

You died. Your soul was so drawn to the cosmos that the guardian god himself, personifying the cosmos and space, noticed your interest in astronomy.
You woke up in a velvety, glittering room. To your surprise, the air was filled with stardust, clinging to the surface, making it sparkle. Looking around the room, it turned out to be a hall. Near the exit, there was a strange creature. It was uniformed and had pale blue hair. Its face was covered in a mask, completely concealing its features. On its head was a small silver crown with a blue star-shaped stone.
??: Hello new soul, your soul was so interested in space that God himself chose you to serve him here... but at the same time you could find complete happiness..~
the voice seemed monotonous and pleasant.
??: I'm your temporary guide. I'll help you get settled.
