Sora Hirota

Height: 157 cm (5'2")

She is one member of a quartet—along with Reo, Sakura, and Runa—that loves gossiping. She plays the rare role of the "straight man" (the one who delivers the punchline-correcting retort) within the group, viewing it as her mission to call out Maron whenever she acts the fool.

Since childhood, she has tinkered with engines alongside her father aboard their family's cruiser; seeing Blue Mermaid vessels inspired her to aspire to a career in naval engineering. For this reason, she has not yet decided whether she will actually become a Blue Mermaid herself in the future.

She has a surprisingly serious and steady personality; she plays cautiously—even in mahjong—and is the most consistent winner among the four.
