A Hell Direwolf.
A Reaper.
A Colossus.
These are the creatures which were summoned by Lumina's enemy at that time. Everyone thought that her enemies were already deploying their strongest summons but, they were wrong. Because the ones that came out at that time felt exceedingly more dangerous. To such an extent that comparing them to the first one would be like comparing a hill to a mountain.
There was a good reason why these summons weren't used right away of course. And, it is because of the price for them coming out which, Lumina's opponents were already suffering. With all of them having a kind of wound on their arm. A bite mark, a stab, and a deep cut. Their blood dripping down the grounds of the arena.
"You should've finished us when you had the chance little girl!"
"I don't mind."
"What did you say?"
"As far as your summons go, I'll get as many chances as I want."
"Don't belittle us!"
