Міко

Miko and her best friend Mako are hatched from eggs bought by Ai and Rika. Along with her best friend Mako, Miko was a fanatical fan of an idol named Yu-Yu. She and Mako 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, Miko often attended concerts and meet-ups for her favourite idol, Yu-Yu, along with Mako. They both admit to having acquired 'sugar daddies' in order to be able to afford attending Yu-Yu’s events.

When Yu-Yu committed suicide, both Miko and Mako were quick to follow in his death as soon as possible, though they don't seem particularly remorseful about it.
