A Problem for Gremory's

A very skinny man was running through a building while he was very nervous, his body was losing strength very quickly due to the injuries he had and his blood was also falling to the ground.

-Damn, damn, damn! (???)

The person seemed to be running for his life while a sinister presence seemed to be following him from behind, this evil presence was burning the path he walked on and didn't even seem to be visible.

-Your destiny is to die today and pay for your sins. (???)

The mysterious figure quickly extended his hand forward and chains bathed in fire quickly shot out from them, these chains quickly pierced his victim's chest, opening a hole and then pulling back something that was still beating, something that had a lot of flesh and blood, his heart.

-Contract completed. (???)

The person dressed as an assassin ninja was Hyoudou Issei, a low-class demon who was acting as one of the world's top assassins, the boy made contracts for various races and organizations.

The first contracts were just humans who called on him in the meantime, but later some demons obtained his seal and invoked him to get rid of various situations that seemed unfair.

These contracts carried out in the supernatural earned him fame, but almost made him lose his life several times and he had to be healed by Asia in these missions in which he participated and risked his own skin.

Killing dangerous monsters that were plaguing many people, killing demons that were committing certain crimes and no one knew about them yet, and many other things that almost no one wanted to do, no one wanted to get their hands dirty for that.

His name had to remain hidden and that's why he presented himself only as a demonic shinobi who was willing to dirty his blade for the contract, he also did some investigation before accepting the request.

Dozens of people who tried to use the contract for personal gain and kill some people who didn't deserve it were mowed down, but it wasn't for lack of warning.

The contract in question this time was to kill a demon of the nobility who was using his status as a noble to persecute various others, this person was placing various types of people into his nobility without their consent and the treatment was horrible.

The person who requested the contract was a man who had a family member forcibly turned into one of the pawns, this person had almost been killed. The information had to be confirmed by several sources before carrying out the murder in discreet and non-discreet ways.

"Lucky for me, it wasn't a high-level devil." (Issei)

Hyoudou thought that after more than 10 days of training like this it was enough to level up a few levels, his level was at least 7 now and was probably close to 8.

The power of high-class beings to destroy cities and mountains was what he thought was still far from that, he even remembers Rias showing him a little of her power.

-Do you want to know the difference between a high-level demon and you??? (Rias)

-Yes. (Issei)

-Can your most powerful move destroy mountains or make this city turn into nothing?? (Lias)

-No. (Issei)

-Well, I can do it, and the weakest of the upper class can sweep at least 40% of Kuoh in one attack. I'm not talking about those fancy people who received the bloodline and power, I'm talking about those who are aware of their own strength and honor their status. (Rias)

Issei was understanding a few more things when Rias showed him a video of Sairaorg Bael, the heir to a great house and a high-level devil, a man with short black hair and who had nothing more than his own body.
