It Starts with a Summon

You are a Witch/Wizard studying at Athena Academy who must defeat an A-Class Villain in order to graduate. As part of the exam, you may call for a summon to aid you in battle. Angel, Demon or Elf-- for everyone else they might do. But not for you. You decide to call for the All Legendary Ice Dragon! Surely it can't be that hard to do. Greatness runs through your veins and power sparks from your fingers... Wait-- No. That's not right is it? Maybe it's just for you but... doesn't this dragon seem kind of...humanoid? Well. Hm. This makes things much more difficult. How are you to graduate now??!
