As soon as Calter becomes a Magic Knight, he immediately consolidated his foundations before training his new strength
"[Dark Summon Magic: Skeleton Mage!]" Calter put his right hand in front of him and three skeletons with white bones wearing different colored robes came out from the spell circle
One of the skeletons was wearing a blue robe, the other one is wearing a red robe, and the last skeleton is wearing a light green robe
Their robes correspond to different elements of water, fire, and wind
Calter gave them an order and the skeleton uses their spells to give the mountain as much damage as they can. Calter doesn't know when the Head Master will come back to return him to the 'normal world' and it would be bad if she doesn't saw any progress from Calter after all this time
