Aqualung
Essential for breathing deep, but often repurposed for partying on the surface.
In the vibrant world of Grand Blue Dreaming, the Aqualung represents the standard open-circuit SCUBA apparatus utilized by members of the Izu University Diving Club. While technically designed for safe underwater respiration and exploration, this gear often serves as a central prop in the series' chaotic blend of diving education and collegiate party culture. It is the bridge between the club's legitimate aquatic ambitions and their frequent surface-level debauchery. For protagonist Iori Kitahara, mastering the Aqualung marks his transition from an outsider to a true diver. However, for veterans like Chisa Kotegawa or the eccentric Gorou, it is merely another tool in their arsenal of oceanic adventures and social gatherings.

Lore & Background
The Aqualung holds a dual significance within the narrative. On one hand, it symbolizes the technical discipline required for safe diving, reflecting Chisa Kotegawa's professional background and her dedication to teaching Iori proper safety protocols. The gear represents the beauty of the underwater world they seek to explore, from coral reefs to shipwrecks. Conversely, the equipment frequently becomes a vehicle for comedy. The club members are known to prioritize social bonding over strict adherence to diving manuals during downtime. This creates a humorous contrast where life-saving technology is surrounded by beer cans and casual attire. Despite this, serious moments of underwater camaraderie often revolve around sharing air or assisting a struggling buddy with their regulator. Ultimately, the Aqualung is more than plastic and metal; it is the medium through which the characters bond. Whether they are struggling with buoyancy control or celebrating a successful dive on the beach, the gear remains constant in their lives.
Reader's Guide
Technically, the Aqualung consists of a compressed air tank and a regulator that reduces high-pressure gas to ambient breathing pressure. In Grand Blue, proper usage involves buoyancy checks, equalization techniques, and monitoring air supply depth limits. However, misuse is a recurring comedic theme. Characters occasionally treat regulators as straws during surface parties or wear full gear while engaging in non-diving activities like karaoke. This highlights the gap between Iori's earnest learning curve and his friends' relaxed attitudes toward safety protocols. Iconic moments often involve Chisa correcting Iori's finning technique or the group struggling to assemble equipment under time pressure before a dive trip. These scenes emphasize that while the gear is standard, the human element remains unpredictable.
