His work wasn't anything really complicated:

He had to deliver Flug´s inventions to customers, steal some artifacts from heroes or sometimes go in search for enchanted amulets and such from ancient temples, Do mundane task such as going to the store and buying things since the others were too absorbed into their tasks to be able to take time to do that, ect.

The catch? He had to travel to different parts of the universe for his deliveries and robberies

Sometimes, the job proved to be deadly.

Getting chased and almost eaten alive by monsters, losing an arm or a leg, having to kill someone who tried to stop him from accomplishing his job…

All of those were almost daily events.

While he didn't find the idea of killing appealing, and, tried not to whenever possible, sometimes there wasn't another option.

He didn't care much about how deadly his job was, after all, he knew he couldn't die even if he wanted to.

He had the time to get to know everyone working for Black Hat:

The cute lizard girl that was head over hills for the eldritch

The naggy megalomaniac scientist who did everything he could to make their interactions as uncomfortable as possible (not that Elisse helped much with that, anyway.)

The cute and cuddly bear who enjoyed to play fight with him and who Elisse tried to teach to sneak and do other predator stuff even if he knew the bear would fail do to his color and size.

And finally the monster himself, Black Hat.

Black Hat wasn't really, as… "insufferable" as Elisse imagined him to be.

They hadn't talk much besides work and an occasional attempt at scaring or intimidating him as he did with the rest of his crew

It didn't work quite as how the villain would have wanted it to.

The most fear he had even gotten out of Elisse was a little gasp when he startled him

And even then it didn't really last long.

But he didn't have much to complain about besides that

Elisse was efficient, pretty apathetic and antisocial, but efficient

And that's what he was searching for

Elisse didn't care what Black Hat did with whatever he stole most of the time

But, he did feel guilty some days, especially if there were any causalities caused by whatever they used.

He cared about killing innocent people

Not heroes, not villains, but innocent people.

He cared about their suffering, even if he didn't mind hurting a hero or even stealing from them

People who were already into that world were likely to suffer, regardless of what side they rooted for.

They were supposed to already know that, but the fear in some of their eyes and their cries of agony proved him wrong.

He tried not to get attached to anyone precisely for this reason.

Not that he cared for anyone on his or the opposite side

Except for a few, selected, exceptions to the rule

He cared for 5.0.5

He cared for Dementia and even talked to her from time to time

He cared about his "family" and tried to write to them as much as he was able

He still had feelings, as much as he tried to deny that to himself.

They all already knew how they would end up, and feelings were just going to make things more complicated than they already were.

His time off was mostly spent working on devices he created to compensate for his weaknesses

He had a seal on himself that prevented him from using any of his demon powers

But he had learned a lot to compensate for it

He had adapted and overcome this obstacle

He was smarter than he appeared but he didn't want to be seen as a threat

He had studied ancient Garufian magic, engineering, self-defense and knew how to use a multitude of weapons from his time as a hitman.

The rest of his time was spent searching for a particular hero.

Any data, trace or location that could let to him finding this particular hero

Nobody knew why exactly Elisse was so interested on searching for them

Vengeance perhaps?

Elisse refused to answer to his motive most of the time.

He had to play dumb most of the time to gloss over any kind of question he would get.

After all he was no novice in the art of pretending

He knew Flug has began to suspect him from day one but, the scientist, smart as he was had been known to get jealous and be overly dramatic any time Black Hat complimented other villains or was interested in them

He had a superiority complex that probably existed to compensate for a poor self steem.

Everyone misinterpreted or dismissed Flugs distrust of Elisse as jealousy much to the convenience of the demon

There was always tension present whenever they interacted

A silent battle of egos and prides that wasn't visible to anyone but themselves

Still, Elisse had the advantage of having his façade very well constructed.

He had always felt like he was in the pinnacle of what he had wanted to accomplish.

He had an stable job

He had a lot of resources thanks to working in a villains base

Time and pretty much creative freedom to create whatever he needed

But, the cost he was paying was very high.

If he wanted to play villain, he had to bare all the weight that allegiance meant to his conscience

Slowly, day by day he was getting more and more numb to everything happening around him

He knew that the organization had kidnapped innocent people and forced them to work for them

He also knew some of them were used as tests subjects for Flugs inventions

He knew that, while he liked Demencia a lot she was willing to harm or kill whoever if it meant getting Black Hat´s favor.

He knew that nothing he cared about hold any weight anymore.

His search was fruitless

He could never return to his family because they would be in danger

He couldn't do anything to help all the innocents in this mess if he wanted to keep his job

And he needed the job, at least until his research was done for

But what would he do when his objective was finished?

He didn't know if he could shake the villain title off even if he didn't really comit any big crimes

He didn't know if he could live without the rush of adrenaline he got from stealing and killing sometimes

And if he was out of the organization, he would surely not have any way to help anyone who fell on to this horrible void

He would never be a hero, even if sometimes his intentions and actions could be considered heroic, simply because he felt an enormous disgust for heroes.

He would never work for them because their view on justice was tainted and corrupt

If he needed to, he would create justice by his bare hands.
