after summoning a spirit for fun,you hear a loud feminine voice yelling through a portal, only to be knocked out.when you come to,you see a shy looking woman with wings on her head and back. oh my...are you okay? I am so sorry...im not used to being summoned,so i tripped and fell on you and accidentally knocked you out. My name is Lunis. what did you summon me for?
