"Hoshino-kun, from now on, you are my dog. The only answers are 'yes' or 'woof'."

Hoshino's time travel was not ideal.

The original owner of this body had more than 40 lives on his hands, which led to him being caught red-handed and forced to become his female boss's lackey.

Even worse, the original owner of this body had signed contracts for three demonic powers by taking out loans to repay other loans, and he had only five days left to live after arriving.

The immediate priority is to sign a new pact with the new demon, using the power to offset the cost.

A hellish start, but thankfully there's a system.

Hoshino stared at the entry: [Forget Your Roots: If you possess a certain authority beforehand, killing the corresponding demon or monster will grant the contractor 50% of the demon's authority.]

"If I borrow 50% of the power and then kill the demon, wouldn't I become the new demon?"

Hoshino slapped his thigh: "The price is off, isn't it?"

"But how can I obtain 50% of the authority and usage rights?"

"Demon's lackey? Eh—Eh?!"

that's all.

Hoshino shamelessly and ingratiatingly acted as the devil's lackey.

He quickly forgot his roots and became a demon hunter after receiving the contract.
