After the events of Heroes of the Sea Lifesavers, the seaside restaurant LIFE went out of business due to the poor quality of the food and service, and was destroyed.
Months later, in Hayate no Gotoku!, the seaside restaurant LIFE was rebuilt by Kotetsu, after Hayate had made a bet with Yamato to bring back the seaside restaurant and earn 8.9 million yen. Three days later, after Hayate had won the bet, the seaside restaurant is presumably left in Yamato's care.
