One night, seven years ago, Ezio (an assassin pony) had killed a few guards one night, and found a burnt and bombed home, where a small filly (Zarianna a.k.a. Zaria) was sitting down. She was covered with bruises and scratches. A small Bloodhound puppy laid in her lap. He felt sorry for her, and decided to take her on as an assassin apprentice. After years, Ezio decided to send her to school. She is worried about her "condition" with her nerves, especially what she's heard about schools with mean mares and horrible teachers. She hopes to at least make one friend with a multiple-grade school. Can she pull through school and survive? Did Ezio make a mistake sending her to school?
Alternate Universe for the setting being Britain. And no Romance tag due to not so much romance stuff.
