Raiden, Astrid and The Twins

Raiden and Astrid just watched as the young girl began battling the three magic users, and when she transformed, the large energy that was released shattered the ice dome, blowing the ice away, however they did nothing to help the girl realizing if she had the power to stop the combined attack from three magic users one of which was even stronger then Rogue then they would just get in her way and the priority at the moment was stop that crystal falling into the wrong hands. They then restrained the twins and stop them from continuing their attack which so far had hit no one the four then simply waited

Dagur. 

Dagur watched as the girl defended herself against three magic users, he saw that she was getting more and more stressed every time she noticed a new magic user. He smiled and decided she would be his first target. He decided to join the battle against her and team up with the other three magic users. He teleported behind the girl and used his magic to cover himself in stone armor, then he set his fist on fire and simply punched her in the face. This would not do much damage as he did not put a lot of magic energy into the attack. It was simply meant to reveal himself as a magic user to make the girl panic more, making it easier to defeat her. 

Sabrina

Sabrina watched as the girl was getting ganged up on by multiple magic users. She simply used her Nen to create a small portal underneath her, she would fall through it, making Dagur's attack miss completely. As she fell through the portal, a second portal opened beside Sabrina and the girl came through it. Sabrina looked to her and smiled as she said. 

"Let's take them out together."

With that she placed both hands on the ground and used her alchemy to create hundreds of stone cannons out of the ground and as all the cannons began firing at everyone who had attacked the girl so far, she infused a small amount of Nen in each of the stone cannon balls that were fired, making them hard as steel and increasing their power and speed. The Nen would also explode on contact, she added this little feature because she saw Drayko could eat the elements. So if he would try and eat cannons, they would explode in his mouth however the explosion would not produce fire rather a strong shock wave of Nen aura breaking his jaw and shattering his teeth at the very least. She then stood back up and took a deep breath, as her dragon flew over to her and stood behind her, they both prepared to defend themselves and the girl from any counter attack.

Ryuji 
 
Ryuji watched as three groups of people formed in the battle. The first group was the inhabitants of Berk. The second was a group of four magic users and one dragon slayer and the final group was two magic users. Ryuji noticed that one of the magic users in the second group had enslaved a large white dragon, and another one was using dark magic on her own dragon, causing it a great deal of pain. Ryuji had now identified two of his targets. He calmly walked over to Sabrina and the girl and got ready to join the fight.
