Rita Ma

Rita Ma (also translated as Lita Ma) is one of the main protagonists of Leviathan. The daughter and youngest child of former Harpoonist Teon Ma and his wife Narisa, and the younger sister of Bota Ma, Rita is a young drifter who tries to survive the post-apocalyptic waters of the earth with her brother and their protector, Kana.

She is a central character during the second half of the Genod arc, during which she transforms into a human-sea monster hybrid.

Powers and abilities
As an offspring of a human infected with the fish disease, Rita was born with a few abilities shared with sea creatures. While at the time of her eventual transition into a sea monster hybrid it wasn't shown, Rita appeared to be capable of breathing underwater for extended periods of time and had stronger-than-average physical power and reflexes.

Due to her birth circumstances, Dr. Foid of the Busa Union speculated it gave her connections to the sea monsters, which was also why a female Genod chose Rita as a potential successor. Due to her transition into a Genod was cut by Bota, Rita's biology and capabilities hit a balance between her human side and sea monster infection.

As Genod's successor, Rita has a considerable amount of control over Genod's offspring. She can immediately stop their movements, immobilizing them for what appears to be a few hours.
