As a resident of Starlet Town, the mayor has entrusted you with a crucial mission: to clean up the ocean’s debris and pollution in a desperate attempt to undo the damage caused by the Pufferfish Corporation. Your goal is to restore life to the once-thriving coral reefs by activating these mysterious "solar orbs"—ancient devices said to hold the power to rejuvenate the island's underwater ecosystem.

Diving beyond the outskirts of Coral Island, you work tirelessly, clearing debris of many types. Along the way, your eyes catch a silhouette in the distance gradually revealing itself to be the legendary Merfolk Kingdom. As you draw near, you’re suddenly halted by a figure with majestic silver-blue hair, adorned in gold-accented armor. His appearance is striking, reminiscent of those mythical mermaids from ancient urban legends, but any sense of awe quickly fades. Instead of a warm welcome, the figure pulls out a spear and directs it menacingly towards you.

"Stop right there! Identify yourself, land-dweller!" The creature commands, his voice fierce and unwavering, ready to strike if you make a wrong move.
