Sebastian x Beast

We were the same height

Endless Kuroshitsuji Moments: 13/★

She is shown to have the initiative to part from Baron's Kelvin's orders. While she complies for Joker and to protect the children back in the orphanage, she can't stand to keep hurting innocent children in return and watch as Joker's spirit crumbles.

Not only do we clearly see her moral ground, we also see how deeply painful this situation is for her because of how it hurts the people around her, especially Joker.

During this discussion, Joker is completely dissmisive of her feelings, pushing her away. She is emotionally upfront and when she was about to tell Joker that she loves him, he cuts her off.

He basically tells her that they have no choice but continue to uphold Kelvin's orders, and leaves her behind.

Beast is completely torn, and Sebastian, being the demon that he is, takes advantage of this, sexually coercing her in the process.

She needed Jokers comfort and reasurance. And just like Joker and the rest of the circus trope—she was a victim of Kelvin and needed to seperate herself from that dark world just as much as the rest.

Beast’s moment of vulnerability with Sebastian is especially tragic, not just because he manipulates her, but because it underscores how utterly alone she truly was. In that scene, she’s desperate for comfort, for someone to listen, and Sebastian, ever the predator, exploits that need.

But what cuts deeper is the realization that what she actually needed was simple: an outlet for her pain, and the reassurance Joker failed to give her.

Her trust in Sebastian is misplaced, yet painfully understandable. After a lifetime of obedience and unrequited love, she’s never had the chance to voice her fears or doubts.

When she finally does, it’s to a demon who weaponizes her honesty against her. There’s something uniquely cruel about that, her one moment of emotional openness becomes another step toward her death.

Something about the way Beast calls herself and the rest of the troupe Kelvin's possesions is so twisted, but it gives us the grasp of the abuse they went through by the hands of their "father."

Kelvin quite literally owns them, and Beast (as well as the rest of the trope) allows him to do so because not only do they feel like they "owe" the man for saving them, the lives of the other kids back in the workhouse are at stake if they don't please him.

When she finds out Sebastian indeed used her to get information, she feels awfully guilty. The circus trope blames Doll for befriending Ciel, but beast knows that deep down, it was her who fell into the trap of the enemy.

The scene where Doll apologizes, only for Beast to immediately cut her off with ‘you are not to blame.’ reveals so much about Beast’s crumbling psyche.

Her guilt isn’t just over the mission’s failure; it’s the crushing weight of knowing she allowed Doll, the youngest and most innocent of them, to shoulder the blame first. In that split-second reaction, we see Beast’s self-loathing collide with her protective instincts.

That fleeting moment of raw honesty where Beast reassures Dollis instantly smothered the second Doll presses further. With a hardened ‘It's nothing,’ Beast slams her mask back into place, retreating behind the role of the Circus’s unshakable strongwoman. But this isn’t just deflection; it’s self-sabotage.

She’s trapped between the need to be heard and the terror of what might happen if she truly is. 

Sebastian’s former act of ‘kindness’ is so insidious because he exploits this very contradiction. He offers her the illusion of being seen, only to weaponize her feelings for further gain. Meanwhile, Doll, the one person who might have understood (considering she was decived by Ciel too.) is brushed aside. 

Beast’s death scene is a masterclass in narrative cruelty: not just for its violence, but for how it mirrors a lifetime of being stripped of her humanity.

When Dagger throws himself in front of her, taking the fatal blow, her raw, guttural screams aren’t just grief, it's also the sound of someone who has always been forced to watch others suffer for her survival.

And then Bard, speaks up, he says:

The line isn’t just tasteless; it’s deliberately degrading. In her final moments, Beast is reduced to the very things that defined her suffering:

A Tool for Others’ Use: Just as Baron Kelvin weaponized her loyalty, Bard reduces her to a tavern fantasy, erasing her pain under the male gaze.

An Object of Exploitation: Sebastian’s manipulation (feigning intimacy to extract secrets) is echoed here, she dies as she lived: a thing to be used, never seen.

A Martyr Without Witness: Dagger’s sacrifice is framed as noble, but Beast’s agony is met with indifference. Even in death, her grief is trivialized.

The arc denies her any dignity, the narrative itself treats her as expendable. The fandom overlooks her, the characters dismiss her, and the world ensures she dies unheard.

This is why Beast’s tragedy lingers. It’s not just her death, but the way the narrative denies her even the smallest mercy: no one truly sees her. Not Joker, who dismisses her; not the other circus members, who are trapped in their own cycles of abuse; and certainly not Sebastian, who treats her vulnerability as a game.

Her story is a quiet scream in a arc full of louder tragedies, and that’s what makes it so devastating.

It’s a perfect scene of how truly terrible Sebastian can be, and it’s diminished down to being commented on as “hot” or “I wish I was her.” All the while completely ignoring the fact that she had been coerced! She didn’t want that! And neither would they want it, because they would still be taken advantage of by a person who doesn’t see them for more than just an object to be used.
