Since then, time has moved forward.
All of us have matured a little.
But despite the fact that we are all flying in different directions in order to fully stretch our wings,
we are still soaring beneath the same sky.
That is easily understood after carefully listening to each of our singing voices.
Chapter: "sonate pour deux"
Chapter: If There's No Name on the Wing
Chapter: Stereophonic Love
Chapter: The Final Interview
Chapter: Nobody Sleeps Tonight
"sonate pour deux" and Nobody Sleeps Tonight gives closure to the entire SPS series. The middle three chapters are side-stories.
"sonate pour deux" — narrated by Naomi
If There's No Name on the Wing — third person narrative on a guest performer for feketerigó
Stereophonic Love — third person narrative on Yuri
The Final Interview — narrated by Naomi / Kyouko
Nobody Sleeps Tonight — narrated by Tetsurou
Tetsurou gets no illustration, despite being the narrator. Kind of sucks.
