Dive!! is a sports anime based on a light novel series by Eto Mori, following the journey of the Mizuki Diving Club (MDC) as it fights to stay afloat. Facing financial troubles, the club is given an ultimatum: produce a diver who qualifies for the Olympics, or shut down. At the center of the story is Tomoki Sakai, a junior high student deeply inspired by the diving skills of his senior, Yoichi Fujitani. Alongside his friends Ryo and Reiji, Tomoki trains under their new coach, Kayoko Asaki, whose rigorous methods and focus on achieving Olympic success push the group to their limits. Adding to the tension is the arrival of Shibuki Okitsu, a dynamic diver with a contrasting style, creating rivalry and camaraderie within the team.

While the series explores themes of ambition, perseverance, and friendship, it also delves into the challenges of teamwork under pressure. The characters navigate personal struggles, intense training regimens, and emotional conflicts as they strive to achieve their Olympic dreams. The show blends technical diving details with personal drama, offering viewers a mix of sports action and character development, though it often draws comparisons to similar works like Free! due to its thematic and stylistic choices.
