Theos vs Vampire King Ezreal

But before the battle began, Theos declared with a smile. "Let me make this clear, I am not a challenger, I don't want to be a King. I want to kill you so that you stop being a King and finally the Vampire race of this territory will prosper."

His words caused a violent reaction from Ezreal.

"How dare you!" he roared.

Like a meteor, he flew swooping towards Theos, extending his sword to perform a great slash, but Theos already predicted his moves.

With speed, he moved to the side to dodge the powerful attack that hit the ground, leaving a giant crater.

'My, if that isn't a monster,' thought Theos. 'His terrifying power, worthy of being a Grand Master rank.'

According to the strength he perceived in that attack and also thanks to Ezreal's information in the novel, it is a Grandmaster rank, an Intermediate Grandmaster more specifically.
