Yato’s Older Sister Case : Haku-san
—That’s right, Haku and Yato are not blood-related sisters.
Everyone around them believes they’re real sisters, but in reality, they’re complete strangers with no connection. Haku’s parents went missing when she was young.
As a result, she was taken in by the agent organization “Dark Card Agency” that her parents had belonged to during their student days, and became a member.
To be precise, Haku was taken in by Ren’s mother, who was the leader of the Dark Card Agency at the time, and Haku volunteered to become an agent to repay that kindness.
Those around her didn’t really expect that much from Haku.
However, for Haku, who had been left alone, it was an essential act to create a place where she belonged.
Eventually Haku grew up, and with her compensation as an agent, became able to live on her own. It was around that time that she found Yato.
Yato was sitting on a park bench, sleeping as if cut off from the world.
When she first saw Yato, Haku was so captivated by the sight that she couldn’t help but stare.
It was as if a hero who had saved the world had collapsed on a park bench in a now-peaceful park. It gave off such an impression.
There were two reasons: the Yato that Haku discovered was covered in wounds.
And in her hand, she gripped a single deck.
These things told a story about what Yato had experienced before losing her memory.
Eventually, Yato woke up.
Having lost her memory and remembering only her name, Haku reached out her hand to her.
For Haku, who had lost her parents and thought she could only live alone, Yato was an existence she couldn’t ignore.
In the end, with the help of the Dark Card Agency, Haku and Yato became sisters.
That is the secret the two of them carry.
Yato, who lost her memory, might not even be human from this world.
More accurately, it’s unclear whether she’s even human at all.
So at first, she had quite a struggle adjusting to this world.
She didn’t know how to use money, how to use a smartphone, or even the rules of daily life.
Still, little by little through effort, Yato became a “normal girl.”
Because she watched that, because she supported those struggles by her side.
Haku wanted Yato to remain a normal girl.
She wanted her to live an ordinary life, ordinarily.
Going to middle school normally, living without any danger.
Haku wanted to create such a world.
However, fate cruelly invited Yato into the world of fighting, as if trampling on Haku’s wishes.
From the beginning, Yato is a special existence.
A girl covered in wounds who collapsed and lost her memory couldn’t possibly not be special.
So Haku was prepared that someday, somehow, Yato would be caught up in some major incident.
That’s precisely why Haku, as an agent, needed to protect Yato. But ironically, the first fate to involve Yato came from a place unrelated to Yato herself.
The Dark Fight organization “Hound.”
Haku and Yato were attacked by an executive of Hound.
Because Haku possessed rare cards, and above all, because she was an agent of the Dark Card Agency.
The one targeted was Haku, not Yato. And Haku was defeated… and fell into evil hands.
Brainwashed, she hurt many people. Among them was Yato.
Moreover, the one who saved Haku was Yato herself, who had become an agent.
In the end, Haku had dragged Yato into the world of agents.
However, Yato after becoming an agent seemed very fulfilled.
She grew close with the manager of the card shop “Duelist.”
She became best friends with the employee Erea, truly the kind you could call close friends.
The activities within the Dark Card Agency must have suited Yato’s nature too.
Yato became remarkably stronger as a fighter.
Surely now, even if her secret bared its fangs at Yato, she could overcome it.
—Because she felt that way, two kinds of darkness were born in Haku’s heart.
One was that, as a result of trying to protect Yato, she had dragged Yato in and hurt her.
And the other was that, as a result, she had constrained Yato’s way of life.
Such darkness in her heart began to sprout little by little in the depths where even Haku didn’t notice… and would attract a certain demon card.
It was supposed to.
And here, our manager makes his entrance. Boom.
Originally, Haku was supposed to pick up a single card by chance.
[Masquerade Vorpal Bunny].
When Haku picked it up, it wasn’t a demon card yet.
It was merely a card that was “becoming” a demon card.
That’s why Haku picked it up and took it home.
Then, [Vorpal Bunny] would dig out the darkness in Haku’s heart and make Haku fall to evil.
But, however. The fact that it wasn’t a demon card at that point means it’s subject to the manager’s “bug.”
That thing where his trait of not being able to get involved in incidents involving demon cards and his trait of eliminating incidents just before they occur malfunction.
Moreover, unluckily for [Vorpal Bunny], around that time “rumors of a legendary card” were spreading through the city. And those rumors reached the manager’s ears too.
And the manager is, so to speak, an existence like an angel of God.
Such a manager has godly power dwelling within him that purifies evil cards.
Or rather, the aura of “Primordial Holy Angel Ancient” automatically purifies evil cards.
If it were a demon card, it wouldn’t be purified even so.
However, for a card that’s merely becoming a demon card, it’s super effective.
At this point, it’s all too natural that when the manager picked it up, that card became [Legendary Masquerade Vorpal Bunny] (a very emphatic assertion).
—Thus, Haku’s dark fall plotline was blown away somewhere after an ultra-C level spin.
What remained afterward was only the dark fall costume that Haku was supposed to wear.
That is precisely the costume that “Moon Rabbit Mask” currently wears.
This costume was placed in front of Haku when she woke up the next day after bringing home [Legendary Masquerade Vorpal Bunny].
Originally, it was the costume that [Vorpal Bunny] was planning to dress Haku in when it made her fall to darkness.
However, [Vorpal Bunny], which had become neither a dark card nor anything else, couldn’t possibly have such power remaining. It could only leave behind the costume.
And if she’s not fallen to darkness, Haku is basically an exhibitionist.
Through the manager’s guidance, with the darkness that had stuck to the depths of her heart gone somewhere, Haku freely put on that shameless costume.
Obtaining [Legendary Masquerade Vorpal Bunny] must have been some kind of divine will too.
Thus Haku decided to act as a street fighter while hiding her identity.
That is “Moon Rabbit Mask.”
One of the strange street fighters who have recently been causing a stir in the city where the manager and others live.
Originally, Haku had no intention of letting her acquaintances know her identity.
Because even Haku would be embarrassed if acquaintances saw this form.
However, fate cruelly invites Haku into a world where her identity is revealed, as if trampling on her wishes.
The incident begins to move significantly when her identity is discovered by the manager—in a sense, the acquaintance Haku least wanted to know.
Just before Haku, having lost the fight, begins to tell the truth.
Yato happened to pass by that place—
