A Ninja and an Assassin Under One Roof (2025) s01e10 Episode Script

1
This is good, kunoichi.
You've improved on your
Western-style cooking.
Right?
But I'm getting tired of feeding you.
It's your fault I'm like this.
You're going to have to
thoroughly take care of me.
When you put it that way, I really can't argue
Who could that be so early in the morning?
I wonder if it's the Calcium Lady I ordered.
It's supposed to be good for healing
broken bones, so I set up weekly delivery.
Go get them for me.
Okay.
Sorry to keep you waiting.
Calcium Milk
Is this the residence of Izutsumi Marin?
Not really, but yes.
Here is her order of the milk set.
That'll be 1,200 yen.
Oh, I guess I'm paying for it.
This is on the house.
Apple
A promotional gift for your first purchase.
Apple juice! This is free?
Yes. Since it's a promotional gift.
A Ninja and an Assassin
Under One Roof
A Ninja and a Baby Assassin
Leaf 10
I got the goods, Marin-san.
Thanks.
Sleepy
Oh. Glasses is awake.
Good morning, Konoha-san!
We received apple juice as
a promotional gift. Here!
Ugh, apple juice?
Not my favorite
Glasses can have my share.
You like fruit juices, right?
I do, but how did you know? Creepy.
I'll drink mine tonight.
Actually, why are you having
your stuff sent to our house?
1000% Sparkling Apple
Apple
Super Good
How long do you plan to crash here?
Don't be so cold. It's only until I heal up.
The reason I'm here in the first place is
because your kunoichi here is a nincompoop.
I've learned my lesson.
I'll take care of you, for sure.
But I see that you don't rely
on your family, do you?
No human who works as an
assassin has a family.
That's usually the case.
I mentioned it before to the kunoichi,
but I have an older sister.
Before I became an assassin,
I lived in a relatively normal household.
I was super close with my sister,
who's five years older than me.
I won again!
Sorry, Marin-chan.
Your pouty face is so cute!
I loved my sister, but
She's a really talented person.
She excels in everything,
was recognized by her school,
and even won awards.
Meanwhile, I get moody and can't perform
well at things I'm not interested in.
Our parents would often compare us.
That was around the time
Marin-chan, let's play a game!
I started to distance myself from
the sister I loved so much.
Then, one day
Mom—
My sister, covered in blood,
stood over my parents' corpses.
Huh?! This story took a turn!
She's gonna kill me!
I was scared and took off running.
When I went back, my sister was gone,
and she's been missing ever since.
After that, I grew up in an orphanage
and was adopted by
the assassin organization.
And that's how I got to where I am today.
Wow, that's horrifying.
Why did your sister do that to your parents?
Who knows?
I'm not sure.
Certificate of
Commendation
Maybe she was dealing with her own stress
due to all the pressure and
expectations from our parents.
Maybe our lives would
be different if I'd stayed
and listened to her side of the story.
Marin-san
But then I wouldn't have
met you and Glasses.
Actually, Glasses reminds me
of my sister a little bit.
If you were just a little nicer to me—
Huh? Where'd she go?
She was here just a moment ago.
Maybe the bathroom?
Konoha-san, where are—
Huh?! Who is this baby?
Wait, could she be
No way This appearance
Is it you, Konoha-san?!
Whoa, she started crying!
It's because you raised your voice.
Huh?! Wh-What should we do?
How should I know?!
Just hold her for now. Hold her!
But I I've never even
touched a baby before.
Even if you've never touched one,
you should know that's
not the way to hold one!
She's finally calmed down.
I just have to rock her
like this? Is this right?
Yup. That's what it says online.
Also, this must be the
doing of a ninja pursuer.
I dunno, but maybe?
Since we didn't turn into babies,
it's safe to assume the apple juice did it.
In that case, that delivery person
should still be in the area!
I'll go find her! Here!
Don't throw her at me without warning!
She really doesn't like me
Anyway, can you really handle it on your own?
Your combatant's been reduced to this.
Y-You're right
And I'm in a wheelchair.
Right now, we have zero strength in combat.
Let's calm down for now and think of a plan.
The enemy already knows where we are,
so we should take shelter elsewhere
She just peed.
Konoha-san?!
I'm sure it was hard to bathe a
baby and someone in a wheelchair.
Good work.
I never thought I'd have to perform
childcare and elderly care at the same time
Marin-san, can't you start walking tomorrow?
You know full well that I can't.
We need to do something about
Baby Glasses here first.
Even if we make a plan,
we don't know when she'll turn back.
She won't be a baby forever, right?
Konoha-san, please hurry and get bigger.
Things You'll Need to Raise a Baby
Clothing
Short underwear3~5 pairs
Long underwear 2~3 pairs
Baby dresses 3~5
Diapers
Cloth diapers30 pairs
Diaper covers3~4
Disposable diapers1 pack
Diaper bin
Bedtime Necessities
We'll need diapers.
And for food powdered milk.
We should prepare a few other things, too.
Sent
All right, kunoichi. I sent you the list.
Take the baby and go buy the supplies.
What? By myself?!
You're not coming with me?
I can't take care of her
in my current state.
And it's hard to get around in a wheelchair.
Baby HQ
Make sure you go out in disguise.
You could be targeted.
And since you're going
to disguise yourself
Thank you very much.
Why a gyaru disguise?
But the employee kindly helped me
when I followed Marin-san's script.
It must be tough when you're so young.
She's my child! I'll raise her properly!
Show me your list!
I'll help you find what you need!
I wonder what that was about.
Right, Konoha-chan?
You're not getting mad at me
even if I call you Konoha-chan.
The usual Konoha-san would
definitely get mad.
No way Here?
I thought she was a ninja pursuer
because of her flashy outfit.
Looking for parakeet!!
If she was, we would have been killed, huh?
I'm going to ask Marin-san to make
us a Roboko that can protect us!
Are you a baby on the
inside, too, Konoha-san?
What are we supposed to do from now on?
Are you reassuring me?
You're right! I can't be upset!
Baby Undies
We also have Marin-san,
so surely things will work out!
Are you hungry, Konoha-san?
We're almost there. When we get home,
you can have milk and
Oh, today I'll make your favorite
curry with lots of honey
Do not feed honey to infants
Huh?
It's unlocked.
That's weird. I know I locked it when I left.
Marin-san! We're home!
Marin-san? Are you here?
Mari—
Huh? Marin-san?
Ninkoro.
Ninkoro.
It's been three days since
Marin-san disappeared.
Since then, Konoha-san has grown rapidly.
No! I wanna go outside!
You can't, Konoha-chan.
The outside is very dangerous.
No! No! It's snowing!
I wanna make a snowman!
Why don't you play hide-and-seek
with Mommy indoors?
No! Mommy sucks at hide-and-seek!
You suck at finding me!
I'll find you for sure next time.
If I can't, we can go outside.
Okay.
Now, count to ten, Mommy!
Okay.
One, two, three, four,
We haven't gone outside for
fear of the pursuers.
But they know where we live anyway,
so they could attack us at any moment.
five, six, seven,
It's scary.
eight, nine, ten!
We can't go outside yet.
Okay, Mommy will come find you now—
They're here!
Huh? Roboko?
It has been three days since my master,
Marin-san, lost access,
so I came to verify your safety.
What? But Roboko, didn't you
Mommy, what was that sound?
What? Konoha-san? Why do you look like that?
"Mommy"? What?!
I'm going to malfunction!
You know about Konoha-san, so you
must be the Roboko from back then.
I see. That is why you've been cowering
at home and did not look for help.
Well, yes.
You are supposed to be the
origin of my AI. How shameful.
I'm just a drop-out ninja. I can't fight.
I was only able to get by because
Konoha-san was with me.
Oh, that spot's sensitive.
And that very Konoha-san became a baby.
I'm scared.
Oh, but Konoha-san has been
growing at a really fast pace,
so I think she'll be an adult in no time.
Maybe then we can figure something out
Mommy, I want this!
Do you think this will grow
up to be the same person?
Oh! But with you here, we have
the strength of a hundred people!
As you can see, my body is
not the same as before.
My current form is made to
support my master's lifestyle.
Mommy, uppies.
Yes, yes. You must be sleepy-weepy.
There's only so much we can do, but let's
start by finding out their whereabouts.
B-But Marin-san's computer
and phone were destroyed.
I believe the ones destroyed were fakes.
Then
Hit!
The real ones are here.
And since they were hidden here
Find My Device
Her whereabouts should be discoverable
through her cellphone.
A-Amazing! Both you and Marin-san for
executing that in the heat of the moment!
Oh? This place is
Do you know it?
Master inputs all her data into me, so yes.
Satoko.
I will need your and Konoha-san's help.
What?
But I just told you that
I'm useless in combat.
And Konoha-san's in this state.
Hot-blooded mode: on!
I can't do anything by myself
Ouch!
Satoko, when did you become so wise?
Because you're scared, weak,
and can't do anything about it
Have you been able to make a
change by using those excuses?
But unlike me, you're smart—
How long are you going to sulk?!

I have been downgraded since my first
form and have no combat skills.
Normally, as a support robot, my role would
be to wait here for my master to return.
However, now I am doing everything
I can to rescue Master.
Do you know why?
Because you, the one I am based on,
are the type to act without thinking.
That had quite an impact on me.
Mommy
And even if Konoha-san cannot fight,
you have the brutal ninjutsu
of turning things into leaves.
The very power that killed me.
Listen here.
That ninjutsu of yours is much
more powerful than you think.
That power can do many different
things depending on how you use it.
Besides, since when were you alone?
Though we are small,
you have me and Konoha-san.
We are going to save Master.
Ruins Guide
By region
Even ruins maniacs
are unaware
But before that
Satoko, it is time to train.
Yes!
You'll slip and fall if you run.
My conclusion is that the person who
kidnapped Master was someone she knows.
Most likely her missing older sister.
Not a ninja pursuer?
This person was able to make a medicine
that turns humans into infants.
They must be extremely intelligent.
There is a high likelihood that they would
know how to make a medicine to turn her back.
Turn her back
If Konoha-san continues to grow up like this,
she might look the same, but she could be a
completely different person on the inside.
To ensure that does not happen,
let us save Master and get the cure.
Mommy!
Look! A snowman!
It's so cold!
It feels good to stay like this, though.
I was thinking the same thing. Just a little.
Marin-chan, say "ah."
C'mon, open wide.
Cut it out! Stop feeding me!
Just leave me alone! I can eat on my own!
But you'll run away if I untie you,
won't you, Marin-chan?
Of course I will!
C'mon, now.
What do you want with me?!
Turning me back into a kid and
keeping me in our old house
You even turned yourself into a kid!
What? Don't you get it?
We finally got to reunite.
I was surprised to see you show
up at the hospital where I work.
That explains why I couldn't find you
no matter how much I searched.
I wouldn't have thought you'd
be living as an assassin.
Not to mention, you were living
with an assassin and a ninja.
I thought it would be hard to snatch
you away with those two around,
so I gave you a drink to turn you into a child.
But you didn't drink it.
Don't you like apple juice?
Not anymore.
I'm reminded of that day whenever I drink it.
Hm?
The day you killed Mom and Dad!
What?
But they were in the way.
Those two neglected you, Marin-chan.
And because of that,
things got rocky between us.
Even though we used to be so close.
So you were smiling
that time because
That's right.
Because I knew we could live
happily together from then on.
But you had to go and run away.
Your big sis was so lonely for a long time.
But it's okay now.
Let's take back the time we lost.
Whoa! What are you—
Let's play some games in the very house
full of memories that we used to live in.
Whoa! What's—
That's enough!
We're here to take back Marin-san!
The ninja girl!
Kunoichi! Glasses! You came!
How did you know?
Also, this is the eighth floor!
We flew to save Marin-san!
Wasn't our grand entrance cool?
Wait. You two seem smaller.
Don't let your guard down, kunoichi!
My sister was a martial arts genius as a kid!
I'm so happy you remembered!
I don't know how strong
you are, Ninja-chan.
But if you have to protect that child, then
Huh? Where did she go?
Here. Now you can run away.
What? Glasses!
What?! Impossible! When did
My child was once a highly skilled assassin!
Hiding her presence is no big deal for her!
Did I do good?
Very good!
Hmm, interesting.
Her nature remains with her even
after turning into a baby.
But what can you do with a bunch of kids?
The only exit is behind me,
and you can't escape from the window.
What'll we do, kunoichi?
We can't leave unless we defeat her!
That's right.
I can't fight.
That's why I thought I wouldn't
be able to save everyone.
But I know now that I can't just
dwell on the things I can't do.
There are things that only I can do!
What are you saying?
What is this shaking?
This is
That's right!
Marin-san has experienced this once before!
I used my leaf-turning ninjutsu
on the building a few hours ago!
Huh? But you'll all be caught up in this, too!
What are you going to do, kunoichi?
What's that?
I told you.
That we flew!
Looks like the plan worked.
Roboko II! You're here, too?
I am glad you are safe, Master.
We built this plan by investigating
abandoned buildings,
testing Satoko's ninjutsu on them,
and then calculating the timing it
takes for different-sized buildings
to turn into leaves.
As expected of a robot I invented!
No way
I finally reunited with Marin-chan
Huh? Marin-chan?
Are you trying to kill us?!
What'll happen to Glasses
if we abandon my sister?!
Oh! You're right! The cure!
Let us continue to lovingly raise Konoha-san
like a flower and fix her then.
Curse you, Roboko!
Growth and Maintenance
Yummy
Here, the reversal medicine.
If you take this and sleep,
you'll turn back.
Also, there's only one of these,
so we won't be able to turn back.
No way! Oh, well.
You're okay with that?
Hey, Marin-chan. Why did you save me?
Huh? Of course I would.
Sure, I'm scared because
you killed our parents
and then turned me into a
child and imprisoned me
But I was also worried about you.
Besides, you're my only family.
I can't abandon you.
Squee!
Marin-chan!
Hey! I'm still scared of you!
I won't say we can go back to
how things were right away.
But we can take baby steps.
Thank you Marin-chan!
I've always thought this, but
Stop, don't come any closer!
Marin-san has such a big heart.
The Next Morning
Good morning.
Oh! Konoha-san!
You're back to normal! How are you?
Do you remember being a baby?
Huh? I do not remember at all.
Remembers Everything
Is that so? That makes me a little sad.
I feel like I lost the baby
I spent all that time with,
even though it was just for a few days.
Well, I don't know what happened,
but it seems you've worked
very hard this time around.
Right, Mommy?
Huh? Konoha-san, do you actually remember—
I don't know what you're talking about.

Mom—Hey, Satoko-chan.
Did you just say "Mommy"?
Nope. I didn't.
But you did?
I didn't.
Oh, Konoha-chan.
Don't turn into Mommy. Stop.
