Nana Mifune 三船奈々
Nana Mifune was a girl who became Collector for the Alien.
Nana is a nice smart girl. She had realized she got the recommendation only because Shuichi declined it. She likes Shuichi and when he looked depressed, she tried talking to him to see if there is something she can do to help him.
