[Next day]
Demon, Aster and Hisha arrived at the academy and were welcomed by the group.
"Instructor Hisha has grown a lot."
'Instructor Hisha we destroyed all the crystal we had and have found.'
"But that cave… it's big and there are a lot of crystals."
'Bring, I look.'
She then showed what she had found out and that elemental magic would work on some of the crystals.
It stated the red ones should be frozen de blue once should be burned the green once should be destroyed by electricity and the copper colored by water.
They lead the way and Hisha saw a lot of small blue crystals.
She asked her brother to use a specific spell and he burned the crystal.
Along the way they assessed there were not much crystals left but when they hit the cave chamber she saw a huge blue and purple crystal.
And a 3rd smaller crystal but it was blue reddish.
'No good.'
"What is it?"
She pointed at the blue on. 'I know.'
She then pointed at the other two. 'Didn't see before.'
She jumped out of her father's arms and walked closer to the purple and blue reddish crystal.
She examined the purple first and found there was something inside, but it was not a monster and the color was that of her purple flame.
She deducted that it could be mana.
She then walked over to the other and felt the mana was the same as hers.
She wondered if she could absorb it somehow.
The crystal became transparent and revealed something inside.
She looked at the third to do the same with the purple crystal, because she felt that the purple mana resonated with hers as well.
Suddenly the crystals broke and the two people came out of them.
Everybody was shocked by what they had seen.
Like it was all natural and knew what she needed to do she did, she put in all the mana she had in to the two individuals and she collapsed.
"Hisha!!!"
He picked her up and tried to get her to her senses.
"Hisha wake up!"
The two individuals woke up from their slumber and heard Demon's frantic please.
'Don't worry, you will not lose her.'
Demon looked up and saw a young women who resembled his mother and a young man who resembled his father.
"How can this be?"
"This will come later, we need to prepare for what's to come."
'The women stroked Hisha's face, you did well, so rest for now.'
Cracking sounds were heard and the blue crystal started to break slowly.
"Everybody get ready for battle who is able to!"
Demon looked at the researchers. "Please take her out of here."
They nodded and ran and told Demon they would inform the headmaster.
The crystal now had completely chattered and a very big monster that looked like a dragon appeared in front of them letting out an defining roar.
"How are we going to kill it?"
"Fire, Hisha showed us how, when we came her."
"But father, you have Ice magic!"
'Lucky us then.'
"What do you mean?" Aster asked.
'Well his hide is pretty durable, bit if we heat him to a certain point and then cool him instantly his hide will be vulnerable and crack easily.'
"Focus on the chest or head."
Everybody was getting ready and the battle began.
The researchers reached the entrance and rushed to the academy.
"What happened?" The doctor asked.
'Later, take care of instructor Hisha, we need to find the head master.'
"Head master!"
"What is it?"
'A monster appeared, and the two other crystals…'
"Alright, I'll head down there you take care of Hisha for now."
The head master stood up and went over to the cave.
