Hatsuseno
Alpha and Takatsu Kokone are robots who appear in a manga by Ashinano
Hitoshi
called
Yokohama Kaidashi Kikou.
There is
currently not an official English translation, however there are a
couple of fan translations available online: There is one on
this site and
another available from
Manga Project.
Alpha runs her own coffee shop, Café Alpha, and Kokone
works for a delivery service. They first met when Kokone had to deliver
a message to Alpha using a "direct transfer" method which appears to
involve connecting sensors that are located underneath the robots'
tongues. They quickly became friends.
Before meeting Alpha, Kokone was focused on being human-like. After
meeting Alpha, she realized that perhaps she doesn't have to try so
hard and she started opening up to just being herself. The two of them
seem to share a very deep connection.
When Alpha's coffee shop was destroyed in a typhoon, she left to wander
Japan for a year. While Alpha was gone, Kokone started going out with
another robot named Maruko, but Kokone still seems fond of Alpha.
There's still a chance Alpha and Kokone could be together again. I hope
so. They're so cute together!
