Wanta

Wanta is a devoted dog who makes an effort to defend those he loves. No matter what, he is always there for his family. After escaping her cruel parents, Mayu first runs into Wanta on Yuigahama. Mayu was about to walk deeper into the ocean, a potentially deadly maneuver given her inability to swim, when the dog's sudden arrival and affectionate expression saved her.

Wanta is ferociously protective of Mayu and the other Maple House occupants, despite the fact that his diminutive stature prevents him from being a serious threat to outsiders. Given that Wanta's size doesn't seem to fluctuate over the course of the series, it appears that he is merely a small breed of dog.

Wanta is unquestionably one of the best anime dogs ever, and his time at Maple House is worth seeing. She is the perfect pet for any home because she can comprehend complex instructions and obediently executes them. The Maple House events and the residents' antics are shown in the anime. Even though it may not be the most well-known anime, Wanta's antics are worth seeing.
