「...dual personalities?」
Someone's mutterings
are exactly in line with Chihiro's understanding.
Dual personalities, or
multiple personalities.
Or so called
dissociative identity disorder (DID), or something like that.
（Yes, that's right,
"Nii-san"）
A voice rang out in his
head.
It was similar to
Hazuki Marika's [Telepathy], but the source was not external, but internal.
In other words, it was
the voice of "someone" inside Chihiro.
And again, the mouth
moves by itself.
**a
「I am Chisato. I am the
personality created by Hana-san's thoughts and my brother's ability. ...maybe?」
「Wait, is that
Chisato-chan who speak... not Chihiro-kun?」
「Yes, Aika-anesama」
Chisato replies.
Aika blushed at the
unfamiliar way of addressing her. But surprisingly, she does not seem to mind
being called "Ane-sama" at all.
Seeing such an exchange
between them, the other members of the group react in their own ways.
Maria smiles from her
blank expression. Riko blinks her eyes with a look of dismay.
「Nii-san...? Do you mean
Chihiro?」
「Yes, that's right. But
I'm a part of him, I guess. Though I'm not sure about that, since I've only
recently become conscious properly. And somehow, I call him my brother」
Since she seems to be
another personality based on Chihiro, it certainly feels right to think of her
as a "little sister".
More specifically, she
is his "twin sister".
Although Chihiro, being
the youngest, has no idea what younger siblings are like.
（Nii-san, would you have
preferred me to be Hana-san's daughter?）
A voice saying in his
mind.
It is a strange
feeling, to hear a voice that sounds so much like his own, coming from
somewhere else.
「No, I think I'd like to
have my first child with Aika...」
「What are you talking
about all of a sudden? You disgusting」
Chihiro answered out
loud, and Hana gave him a terrible glare.
（Nii-san.... It's okay
if you just talk in your mind）
（Haha... I'll be careful）
This time, the
conversation succeeded in silence.
It seems that Chisato
can trace Chihiro's thoughts to some extent. Chisato also seems to be able to
convey her intentions to Chihiro without any explanation.
（Chisato, can you use my
body too?）
（Only while Nii-san
gives me permission. So, if you don't think it's a good idea, I can only watch）
Although it was a
strange feeling to have another person inside of him, there was also something
that felt right.
At least it's not too
uncomfortable.
（A little sister, huh?）
（Yes, because we are the
same person, maybe...）
It might be easier to
understand if he think of her as an upper version of the self-question.
But then Hana's voice
came.
「Wait, so, you really
have dual personalities? Not just Izumi-kun's acting or something」
Naturally, she cannot
hear the conversation in his mind. So, she does not know that Chihiro is
beginning to be convinced.
「Hana-chan, this is
exactly where you start to doubt me」
「That's true. If I admit
it, it means I wanted this situation」
――Misumi Chisato, a fictional character, whom Hana dreams exists.
There is nothing wrong
with that.
If it is only that,
there is no problem as long as it is kept inside of Hana, but if her strong
desire has become an ability and realized, it is indeed embarrassing.
Whether she is happy or
not is probably secondary.
（I might understand her
feeling a little...）
（Yes, you're right....
I'm also embarrassed to have people guessing the origin of my "Mind
Reading"）
While sympathizing Hana
and to prove Chisato's existence, Chihiro tries to surrender control of his
body to Chisato.
Chisato smiled and
nodded his head when Chihiro entrusted his body to Chisato.
「...Even if you say so,
it's hard to prove, huh? Oh, that's right」
While Chisato was
saying that, she thought of something.
She shifted her gaze
from Hana to Riko and smiled.
「What? Me?」
「Yes. Riko-san, can I
borrow your [Illusion] for a moment?」
Immediately after those
words.
「Ah」
「Eh...」
「Whoa」
「Oh, my」
「No way」
The girls looked at the
back of Chihiro's head and each let out a short voice.
Chihiro, who was
curious, turn around to see what's going on.
And he saw himself.
No, it was not.
Not exactly Chihiro
himself.
The base is definitely
Chihiro, but the details are different. The person in the school uniform has
semi-long hair and slightly lighter skin color. Her arms and legs are slightly
thinner than Chihiro's, and her breasts have a modest but female-like fullness.

「Chisato?」
「Yes, Nii-san」
Chisato smiled at him.
Her smile gives a soft
impression that softly envelops the viewer.
Also, her voice is not
borrowed from Chihiro's vocal cords, but is definitely her own voice.
「——」
Unable to believe what
they were seeing now, Chihiro extended his hand to Chisato.
「——」
So did Chisato. She
does the same and tried to put her palm to Chihiro.
However, Chihiro's hand
did not feel anything.
Chihiro's hand slipped
through Chisato's palm.
It is an illusion.
「It is Riko-san's
ability」
Chisato has no body of
her own.
Therefore, other people
can only see and hear with Chihiro's eyes and ears, and speak with his mouth.
But now they can see
and hear her after she borrowed Riko's ability to help her.
「Huh? So, Riko... do you
mean to say that you could make a sound as well?」
「Oh, yes. I've been able
to make it for a while now. Didn't I tell you?」
"No, I haven't
heard that at all," Chihiro thought.
Well, it can't be
helped that she doesn't have many chances to use her [Illusion] in her daily
life.
However, is Chisato
could easily borrowed Riko's abillity?
Chihiro glanced at
Suzu. Sure enough, she is looking at Chisato excitedly.
「You can do that?」
「Yes. However, even if I
borrow it, I can't use it freely. It is not the same as copying or looting」
Shortly, all Chisato
can do is project herself as an illusion.
She can change her
clothes and hairstyle, but she cannot change her body shape drastically or
pretend to be someone else. In this respect, she is bound to the image of
"Misumi Chisato" constructed by Chihiro and Hana.
Moreover, she cannot be
far from Chihiro――perhaps more than ten meters away.
It also seems that
Chisato is partially borrowing Riko's ability which is connected with Chihiro's
ability of [Domination]. Nevertheless, Chisato herself seems to have only
vaguely thought that she could do it, and the details of the principle are
unknown.
「But now...」
「I think Hana-san will
trust me, too, don't you?」
The two brother and
sister――or should they be called――turned around together.
And to Chisato's word,
Hana was in tears.
「I was moved」
Apparently, Hana is
crying tears of joy.
Riko looked at her and
muttered in confusion.
「Umm,
Mishuku-san, aren't your characters different?」
