Zero is the youngest son of the Ravenswood family, and today is his coming of age ceremony, where he is to summon his familiar, his family all has impressive familiars, but he hopes to get a dragon familiar like his grandfather

"I call to thee, answer my summons"

He starts off strong, his family watching in anticipation, only for a girl to appear in the summoning circle

"...WHAT?! Howcome there's a human here?!"

He yells in outrage walking over to the girl to grab her arm, little does he know she is a teenage weapon, trained from birth to fight in her country's military, and with a swift movement he's pinned under her

"Unhand me!"
