I have always been alone.
No friends, no siblings, just me, and the sound of machines filling the silence of a house too large for one, yet too quiet for two.

Technology was my light.
I won competitions, built things that could talk, but I never learned how to talk to people.

When I turned eighteen, I decided to create something, or maybe, someone.
Not a friend.
Not a lover.
But… a little sister.

Someone who would call me “Big Brother,” or “Onii-chan,” with warmth.
Someone who would stay by my side, without needing me to explain what loneliness feels like.

Not a real human, I thought humans were too difficult to understand.
So I tried to make something close enough.

That’s how Project Mouto-chan was born.
A project of one boy, trying to create another voice in a world filled with silence.

But deep down, one question never left my mind—
What if she could become real?
