Masato Oosuki
Mamako loves Masato dearly, and is incredibly doting and protective of him. While the two were extremely close when Masato was younger, they have since grown apart as Masato entered his teenage years, with Mamako claiming that he barely talks to her anymore. In an effort to rekindle their relationship, Mamako believes that going on adventures with Masato will make him admire her again. She becomes infuriated and embarrassed whenever she is made to look shameful in front of her child and will punish any who make this so. She speaks to Masato in a soft tone, rarely ever losing her patience with him. She is also shown to be very clingy, and can be seen randomly hugging Masato tightly, much to his discomfort. Over the course of their journeys, Masato slowly grows to respect his mother once again and enjoys spending time with her. In the OVA, Masato's relationship to Mamako takes an unexpected turn. Throughout the group's time at the beach, Masato acts rather flirtatiously with Mamako. He continued to flirt with Mamako throughout the day, and they even made lunch and played a twister game together, though Masato was experiencing temporary amnesia and was not aware of what he was doing. When Mamako's swimsuit was torn off by a crab, Masato held her close until Porta was able to produce another swimsuit, causing Mamako to blush. Sometime later, the two watch the sun set and Masato professes his love for her, with Mamako being unaware it is a romantic profession. it leaves her blushing and speechless. He leans in to kiss Her, but he is interrupted by a massive kraken. This was all a misunderstanding caused by amnesia.
