SpoilerMako and her best friend Miko are hatched from eggs bought by Ai and Rika.
Along with her best friend Miko, Mako was a fanatical fan of an idol named Yu-Yu. She and Miko attended concerts and meet-ups together in life. She is very cheerful and enthusiastic when talking about Yu-Yu, and very happy to see her best friend in the dream world.
In life, Mako often attended concerts and meet-ups for her favourite idol, Yu-Yu, along with Miko. They both admit to having aquired 'sugar daddies' in order to be able to afford attending Yu-Yu’s events.
