Best friend or another obstacle?
While Eden was fighting Elric, their future teachers were still watching them earnestly. The future generation seemed to be really talented, and they didn't doubt even a second that these two, including others as well, would be prominent figures later in a near future.
However, in all those people that were watching the battle, just one of them couldn't think straight, especially during Eden's last move.
Yes, this person was Cayron, and it surely didn't escape Solomon's attention.
When he saw this spell, 'The sword of icy dreams', all Cayron could think of was Kila.
Kila was the one who invented this spell, and he even witnessed it when he fought the three slime bosses, and later on the insect bosses. This spell was so beautiful, enchanting, and destructive that even twenty years later, he didn't forget about it.
