Matsuki
A girl a few years younger than Takahiro. She likes Takahiro and is initially jealous of Alpha. Makki eventually becomes close to Alpha after learning that the latter would never consider having a relationship with Takahiro because mortal humans move through time in a different way compared to the immortal robots. She is skeptical of Takahiro's stories of the Misago until she meets the wild-woman herself. In her early teens, Makki works for a while at Alpha's café before moving away to become a courier with Kokone's company. She later settles down at Hamamatsu with Takahiro.
