Miss Takamine has been in posession of this Digimon, BlackGaomon, for approximately a month now.  As of today you are to be her supervisor and make sure he doesn't run wild and cause trouble.
A month!?
Because she has declined to join DATS, you are responsible for everything she or BlackGaomon do until the day she changes her mind.  Considering she's your "sister", you wouldn't mind doing that, would you?
She never told me about this!!
(*annoyed*)Can't I at least explain myself!?
Sheesh, this is the guy you keep talking about?
I'll let you two work this out in the meantime.  I know the captain will want briefings at the end of the day on how they're doing.
Hey!!  Don't leave me alone here with this!!
(Yoshino leaves, and a long awkward silence begins between the two)
...Masaru, I'd honestly meant to tell you about him.
Tell me?  How am I supposed to *accept* it!?
You didn't want me to see Agumon!  You think you would've taken seeing a big black dog any better??
He knows my name!  He can say it!
You knew about Digimon before I ever met Agumon!  Is that why you knew about Yoshino and DATS and memory erasing?
...It's...it's really complicated, okay?
You heard my mom!  We don't keep secrets in my family!  And that goes for big black dogs like him!
I got a name, girly-hair!!
I got scared, okay!?  I know you better than pretty much everyone!  If you knew the government was on my back about BlackGaomon, you'd do something that could get you arrested!  Or worse!  I...I don't want to lose any more of my friends...especially not you!
(Masaru is stunned by the outburst, especially by her referring to a certain someone in her distant past)
...Sakura...
I know you don't like keeping secrets, Masaru... I didn't want you caught up in all of this.  I didn't want to put you in danger, not for my sake!  But BlackGaomon and I are friends too, and I don't want DATS to take him away!
How come you weren't harassed to join DATS, too?  You saw what Yoshino did!
...Maybe there was something about Agumon that made him extra special.  They still wanted me to join, but...what they did to you was just weird.
That doesn't really answer my question.
...It goes back to you, mostly.  If I was part of some secret government police, you'd get too worried about me.  I mean, it seems really cool and everything, but...
But?  I'm part of DATS now!  What're you worried about?
...I guess I just don't know.  Everything about it makes it sound so busy and huge and nerve-wracking!  Aside from you, I don't really know anyone there!  Can I really trust them with BlackGaomon, or even me?
Doesn't seem too hard to me.  (*thinks of Tohma and gets annoyed*) ...Aside from some things.
But you're not going to make me join too, are you?
Hey, I'm not here to force you to do anything!  ...If it makes you that uneasy, I won't make you join DATS or anything.  And if the dog is--
BlackGaomon!!
...BlackGaomon...is really legit, I'm not gonna do anything to him.
You really mean it?
Since when did I ever break a promise?  A man's word is iron-clad!
