Loser Park (負け犬公園,Makeinu Kōen?) is the place where Hayate first took refuge after being chased by the Yakuza after his parents had sold him for a 156,804,000 yen. There he met Nagi, who he had planned on kidnapping for ransom, but ultimately failed. After having given up, Hayate met Maria who was looking for Nagi. After having lied to her about Nagi's whereabouts, Maria gives Hayate her scarf. Touched by her act of kindness, Hayate attempts to tell Maria the truth, but overhears Nagi being kidnapped by two men. Seeing the kidnappers speed off in their car, Hayate borrows Maria's bike and catches up to them resulting in him saving Nagi after being hit by their car.
Whenever Nagi and Hayate go to the park, Nagi always reminds Hayate of the first time they met and becomes embarrassed remembering the misleading words Hayate had once said.
