Good Summon, Wrong Summoner

Tori's body slowly started to turn transparent while light particles floated around him. 

Ban was not surprised by the sight in front of him. He already knew that this would happen the moment Delo was killed. 

Every time a Monster was killed, they would no longer have any chance to come back to life again. Their body would remain on the Summoner's World, be consumed by other Beasts or Monsters, be buried by their owner, or left behind to rot. 

However, if the Summoner was killed before the Summoned Monster, their body would slowly fade away along with the light particles. 

According to the Adventurers, if a Summoner was killed, the Monster would return to slumbering, waiting for the right opportunity to be summoned again by another Summoner.

That was also another reason why he was adamant about killing Delo. Not only was it the right choice to begin with, it would also create another chance for the pitiful Tori.
