Fixten

In a world where summoners wield the power to call forth vampires, elves, angels, demons, and all humanoid creatures from across the realms, Nathan found himself unable to summon beings except from beasts. 

However, those beasts are not ordinary beasts. They are divine beings who once stood at the same level, if not higher, than the legendary creatures the world ever knew. 

Casting his gaze to the left, Nathan sees numerous summoners accompanied by the likes of demon kings, archangels, vampire progenitors, and other legendary beings. Turning to the right, a massive army of alien symbiotes is waiting to attack. 

There was no fear in his eyes, because standing on his left is a majestic wolf who managed to kill a god, the legendary eight-headed serpent coils on his right, above him is the bird who is glowing like the sun, and behind him is a dragon that once gnawed the roots of the world tree. 

“Let the war begin.”

Summoners War: Only I Summoned Divine Beasts

"Why did a vampire evolve from sucking my blood?"

When she heard that question, the fairy queen gave an answer as if she had read it in a book. "There are multiple reasons. First of all, do you know what the vampire sucks?"

"Hmm? Red blood cells, white blood cells, or something like that?" Nathan tilted his head in confusion. "I don't know a lot about biology."

The fairy queen shook her head. "Your blood is influenced by your Ena and your soul. If you are a being from another world, it will change your blood as well. And due to your unique Ena that can summon a beast, we know that your blood is different from other people."

"That is weird." Nathan thought for a moment. "If that's the case, why would the one who discovered me to have Ena in my body consider me to have a tremendous amount of Ena? Meanwhile, I only had 60 Ena when I summoned my first familiar."
