AN:- Greetings, old friends! Mystic had been unfortunately hospitalized - Cancer is curable though, please believe it and stay positive! - and she is now finally back! Still recovering, but in the mood to write and I'm stuck spell-checking and uploading for her :)

She will continue the rest of her stories, but for now, due to her current mood-settings, we shall begin with this one...

Prologue

Rum knew that this was necessary.

For creation, destruction was a must. For a new empire to rise, the old one must fall. To triumph, one must first experience loss. For a new beginning, end must precede it.

That was the way of life.

It had been fifteen years since he'd been a part of the organisation. Most members were older than him; in fact, he was the youngest there was. Yet, in the short span of a decade and half, he'd risen to the highest position in the ranks – the right hand of the Boss himself.

Rum could confidently say that he was the Boss's most trusted agent – Vermouth coming a close second; but then it had been Vermouth who had brought him into this organisation after all. He had no need to fear her jealousy when she thought of him as a son. Gin hadn't been quite pleased at his rise in authority, but had accepted the Boss's orders nonetheless.

To most of the members, he was known as an Avenging Angel – quite contradictory, for an Angel to reside in Hell, but fitting. Because he had never killed yet. Rum was, first and foremost, a strategist. A brilliant strategist that far outclassed Gin or Bourbon. And while he may have been the one to orchestrate quite a few deaths, he had never been the one who pulled the trigger.

Hence, Avenging Angel – a pure being that killed, destroyed, annihilated righteously, yet mercilessly.

The organisation's goals were simple – to create a better world.

It had been the Boss's wish to eradicate corruption, working from the shadows to eliminate all those who harmed society, pulling out evil from its roots.

It had been a worthy aim; a good cause that many joined for. But then, somewhere along the way, Boss realised that one life time was too little, too less to complete their mission. Because to truly accomplish what they had been striving for, they would need years, no, decades.

And after creating the perfect place? They would need to maintain it! To make sure dishonesty and immorality didn't squeeze their way back into society. Decades were not going to be enough either – he needed eternity now.

An eternity he couldn't have.

And thus began Project Silver Bullet.

If they were the wolves, then amnesty against their one fatal flaw was required. The Silver Bullet – death – would be conquered by them and they would reign, immortal.

'Mad Scientist' and 'Hell's Angel'; husband and wife, both scientists of great calibre; had been one of the many chosen for creating a drug that would increase one's life-span indefinitely, but they were the only ones who turned out to be successful.

Things had not gone quite smoothly at first and the Boss had turned towards myths – Pandora – in hopes that the fabled gem might provide an answer. Failure had greeted him there too.

Then, APTX-4869, the first successful Silver Bullet, had been created.

The first few versions worked as an untraceable poison. All lab rats had been killed and the organisation began to use it as an assassination method for high risk missions.

Creating a pill for immortality seemed hopeless.

It had been Hell's Angel who first requested a human test subject. She wanted to create a pill and engineer it specifically for one particular DNA. The Boss had volunteered Vermouth – she was his favourite and if there was one person he wanted along with him in his immortal life, it would be her.

But it appeared that the pill had not worked.

The Boss would have left it at that if both, Hell's Angel and Mad Scientist, had not blown up their lab – committing suicide and destroying all their research and papers in the process.

Five years later, Vermouth had yet to show signs of aging.

The Boss had immediately brought in Sherry to work for them as soon as she graduated her accelerated course in America. The girl was, if possible, even more of a science prodigy than her parents. If it would be anyone, it would be her, who recreated it – the Silver Bullet.

The revival of the APTX-4869 worked as its first version had – a poison.

But the Boss forbade any use of it for killing purposes, devoting all time and research to advance the pill to its next level – agelessness.

Rum had been quite appreciative of the organisation's goals.

There was no doubt about that, since he had been the one to concoct many of their plans and carry it out, even if it was only in the role of an advisor and administrator. But, even he couldn't deny how single-minded the Boss had become recently – his only focus being the perfection of the APTX-4869.

Rum was possibly the only other person who was aware of Vermouth's true predicament, the Boss being the first. So, he knew that it was not merely a dream that the Boss was chasing after; it was reality.

But the Boss had become so absorbed in his pursuit of immortality, that their original goal – to create a better world – had been mostly side-lined.

Which was why, Rum had decided.

He had decided that the organisation no longer had a purpose; for they had begun killing to achieve an end that helped none.

And that went against their objective.

And, thus, like any other corrupt individual or organisation, it must be eliminated.

Each and every one of them; the Boss, Vermouth, Gin, Sherry, himself; everyone must perish. They had reigned supreme, together; and they will fall, broken, together. That was their destiny.

Because, destruction was needed for creation. There can be no beginning without an end. There can be no freedom without struggle.

The organisation was turning corrupt; it was promoting stagnancy instead of progress – what else would you call freezing yourself into an un-aging shell of a body?

Stagnancy.

So, he slowly began working against the Boss, creating a plan to bring them down – from within. The plan would take years to come to fruition, but the seeds had been planted and the roots had taken hold; all that was needed to be done now, was to wait.

Wait and watch.

Rum did not consider his actions to be a betrayal; no, he was only doing what the organisation had once stood for. To him, it was everyone else that had betrayed the organisation.

And he was their Avenging Angel – carrying out justice.

Hell's Angel had realised this, realised how far they had fallen; she'd kick started the process by killing herself and her research. And now, it was left to him to end it.

For, among the Demons of Hell, it was the Angels who needed to see the truth and bring about true justice.

AN:- Well, we have so far plenty of suspects for RUM in the manga - Asaka, Superintendent Hyoue Kuroda, Teacher Wakasa Rumi, Chef/Waiter Waketa Kanekori...well, no idea who it is there, but in this particular fic, I'm sure most of you have figured out the identity already! Worry not about the ruthlessness of the BO Characters - they will be done justice [or so Mystic tells me].

Hope you all enjoyed it so far! We hope to keep updates regular, but Mystic's health will be my priority and spell-check and revision may thus take a while.

Thank you all for your support and well wishes!
