This scene is pretty long, and it is really good! It involves Kido Karin and another girl who end up drowning in a pool. Karin seems to get some sort of muscle cramp, causing her to drown first.

There are plenty of panels showing her in a swimsuit, getting rescued by her boyfriend. He manages to revive her.

Another lifeguard pulls a second girl from the pool, also unconscious. She gets a good arm carry panel!
