Hell's serpentine overlord (Hazbin Hotel Harem X male Obanai reader)

Training arc: Tengen's final challenge and Zenitsu's true strength

It's been three days since Charlie and Vaggie had started their training and they seemed to be doing exponentially well.

They were able to avoid some of the traps and in the events some were triggered, they managed to avoid them.

Of course some traps managed to strike them down, ensnare them or generally slow them down.

But yet they still manage to be first to reach the end of their laps and run back.

Now we see the two demon girls resting up, sweat rolled down their entire body as their breathing had become heavier.

They were drinking some soup that Makio and Suma had provided for the entire group and everyone was slurping it down hungrily.

As they drank, they saw Tengen had walked up to them.

Tengen: I gotta say, you two were mighty flashy out there. It almost made me forget you were the princess.

Charlie blushed a little before responding.

Charlie: Well, what can I say ? I guess I just got really used to your training routine.

Tengen: Yeah, well don't get used to it. Not only an I just the first teacher you guys got but there's gonna be a final challenge.

This had gotten everyone's attention and Zenitsu cried out what everyone was thinking at the moment.

Zenitsu: Th-There's more ?! WHY ?! Y/n-sama said once we finish 3 days of your course we get to leave and do the next teacher.

Tengen: That's just the thing, scrub, the third day isn't over just yet and I got a little plan in case you maggots finish earlier than expected

He points his bladed arm over to another much larger mountain in the distance.

Tengen: All of you will arrive at that mountain by 7'o clock where we will begin your final challenge under my jurisdiction. Fail to do so or slack off in any way and you'll be seeing my wives about it. Spoiler alert, they can be worse then I can be.

He motions to the three demon women who smirk, crack their knuckles or balance the blade of a kunai on their finger tips.

Charlie and Vaggie shrunk back a bit, even the fact that these three were considered lesser demons compared to Charlie, that didn't mean they weren't just as intimidating as the overlords.

Vaggie: (Thoughts) Now I see why the rest of the exorcists never came to Y/n's district. If the weaker demons are this intimidating, just imagine how they saw Y/n and his right hand men.

It was then Vaggie remembered the kind of reputation Y/n had gotten over the years with the rest of the exorcists.

Some had their legs torn off by wild animals, others were bludgeoned and pounded by Y/n himself.

Even Lute, who got cocky and tried to kill Y/n got one of her hands fed to crocodiles and beaten half to death by gorillas.

Had Vaggie been one of the unlucky fools to enter Y/n's territory, the wings and eye she lost from Lute would have been an mercy to what Y/n could do to her.

But Y/n do that to her, not now at least, now he was training them to protect themselves from dying to Adam and his angel army.

(Timeskip)

We cut to later in the day as all of the cannibals, assassins, Charlie and Vaggie had arrived at the mountain.

It was quiet, awfully quiet. Normally the group would be hearing the complains of one blonde haired assassin.
