[u][b]Haruko (?)[/b][/u]
A swarm of ants slowly gathers, pushing through the loose gathering of spirits. The others seem to be rather lazy, letting most of them by after a single battle. Haruko sighs inwardly. As an amalgam of downtrodden spirits, they can relate.

Nonetheless, the situation is unacceptable. The entrancing pillar of light, the geyser of tormented brethren, each only now regaining what makes up their very being, is appalling. The eruption disturbed and displaced all of those dwelling in the well, and while all of the spirits knew deep down that a grand revolution isn't feasible or helpful, letting things go without an attempt at retribution, at change - letting things resolve peacefully after seeing other spirits stepped on, abused, and now finally seemingly discarded was unconscionable. The spiritual force of the release was too disturbing for a spirit to stick around to gleam the details, but that the cloaked figure was human was unmistakable. There's no chance at all that this isn't completely the fault of humans.

Let's see...

A bespectacled girl accompanied by the spirit of a vampire...
The girl with the Elf guard who arrived with the host...
The girl with dark world influences...
There's the 4 spiritually inept in red jackets...
And then there's the two Jerry Beans Man and Gokibore have decided to accompany... Hard to keep it against the two spirits. It's in all of their natures to accompany human duelists, after all.

All in all, 9 people have gathered. Quite the crowd. Although the spiritually inept could just be ignored or manipulated, this whole mess isn't really about achieving vengeance against humans, now is it? If that was the goal, then being beaten once wouldn't be the end of things for a duel spirit. About half of these fools know nothing of shadow magic after all, and the other half can only intuit how it works at best, but hounding after humans on repeat, forcing them into duels over and over until they slip sounds nothing but exhausting. Sure, maybe some would die, but it'd be a hollow vengeance when each duel spirit of the well still has a human out there who abandoned them.

Duel spirits can't just ignore what they are. They've done nothing but stagnate without human intervention. A world without humans at all is one where the weak stay weak and the strong trample upon them. It might as well be no different from living at the bottom of a well as they have been.

This is about 'us'. This is about the catharsis of showing these humans not to mess with spirits ever again. A representative? A clear winner? Laughable.

Haruko makes a decision. They'll take on all humans at once, up until they've been defeated or the point where no humans remain.

They're not weak. Not right now. Not with Haruko.

The crowd of spirits, as if coming to a tacit agreement, all begin collapsing on Haruko. Humans, their duel spirits, the two defectors, and the forlorn Scapeghosts rush to get out of the way as a stampede of otherworldly beings begin to vanish as they fade into Haruko as if being absorbed. The glowing aura around her begins to brighten, eventually shining a light blinding enough to rival the geyser of spirits behind them, before it finally calms all at once, and Haruko, still floating several feet off the ground, begins to multiply like a Kuriboh.

In front of each of the humans gathered, a discreet Haruko floats before them. She addresses each of them, and nine voices speak in unison, each an amalgam of other overlapping voices, forming an otherworldly choir.

"I do hope you've all realized your lives are on the line."

Each Haruko materializes a semitransparent duel disk as shadows begin to envelop and isolate each Haruko and their opponent.

The entire world goes black. Each student is all alone in an endless inky void with nothing but a possessed ghost girl dueling them, apparently to the death???

Each Haruko begins drawing cards. It's time to duel.
