Vasha, a subordinate vampire, is trying to regain lost memories and abilities.
Todd, the sole survivor of a fallen lineage, seeks revenge against humans.
They enter into a soul contract, each hiding their own purpose.
However, when making a contract, one must read the terms carefully…
“I, 【 Vasylisha, 】propose a 【 Binding Contract.】”
“I, 【 Todd Van Drake…】”
“What? Todd Van Drake?”
“…accept the 【 Binding Contract! 】”
Vasha, unaware that Todd is both a vampire’s enemy and a renowned vampire hunter.
“You… aren’t you a high-ranking vampire?”
“… Did you notice that?”
“No wonder! A high-ranking vampire wouldn’t consider making a mere human brat their familiar!”
“What do you mean by ‘brat’…”
Todd, realizing too late that Vasha, whom he thought to be a high-ranking vampire, is just a lower-ranking one.
They become reluctant companions due to the existence of an unknown letter.
But is it just because they are enemies?
Despite being the closest relationship one could have in the world, Todd, who is sharp and aloof towards everything in the world, doesn’t easily open his heart to Vasha.
Yet Todd is still young.
Until Todd grows up, there’s time to slowly become friends!
While Vasha tries to raise this stubborn enemy…
Can they each achieve their goals?
