In "Fairy Tail" chapter 512, Larcade will defeat Sting and finish his battle by using the "Sleep" magic. Sting will fall asleep. But in using this magic, Larcade ignores the warning given by the Light Magi. This Magi warned that whoever uses this magic will himself be killed.
He Is Really Set In Killing His Foe
The previous chapter features the potential epic battle between Larcade and Sting, the leader of the Sabertooth Guild. Sting was able to enter the battle when Larcade easily defeated Kagura. Larcade was able to overcome Kagura with his light tentacles. However, these tentacles seem to have no effect on Sting.
It seems that Larcade is really intent on killing Sting in "Fairy Tail" chapter 512. This is the reason why despite the warning, he still used the magic that will bring the ultimate human desire to sleep. A fight between him and Sting started when the latter began to ask questions about his foul smell. Sting realizes that the smell of Larcade is like that of Natsu.
He was confused about this. But Lector and others have explained to him that this Spriggan is a child of Zeref, who is a brother of Natsu. But Sting will not believe this explanation. He said that even if they are related to Zeref, they should not smell exactly the same. Then Larcade revealed that his and Natsu's smell are similar because they are the sons of Zeref.
Larcade Begins To Attack Sting
Larcade then proceeded to attack Sting using the Starvation Magic. Sting looked at Fro as food and tried to eat the creature but it resisted his bites. Sting realizes that it was just Larcade's magic, but he can't resist Larcade's powers.
"Fairy Tail" chapter 512 ends with Rogue giving Sting an advice to eat his shadow so he can regain enough energy for the fight. Rogue also encouraged him as he called for the help of the White Shadow Dragon. But Larcade warned him that he will cast his "Sleep" magic on him.
