Tsunami Ōnami (王奈美 津波 Ōnami Tsunami) is a fictional character in the anime and manga series Desert Punk.
Tsunami is the mother of Namiko and wife of Haro. She first appears in "The Demon and the Double D's" being chased by members of the Kawazu Gang, but is saved by Desert Punk. She was almost a rape victim until the Kawazu Gang deemed her "too ugly to protect." Unfortunately, Punk doesn't do this out of the goodness of his heart, and demands 20,000 yen for each of their lives. She and her family later hid in a cave where her daughter was complaining about their lack of food and money while husband was being bitter about not having the strength to defend his wife and little girl himself. Tsunami herself cried over the fact that she was married to such a " useless tool" who lost all their money they were going to use for their daughter.
