Ewelina is a young scuba diver. She's always dressed in a long-sleeved tight-fitting rubber wetsuit, a diving mask, a pair of rubber gloves, a pair of flippers, a swimming cap, a scuba belt, a scuba breather and a tank that is holding infinite air. She is part of a girls' scuba diving academy with 20 other girls and 10 female diving instructors. The academy is a boarding academy, and the rules require the girls to keep their wetsuits, gloves, flippers and swimming caps on at all times. They must wear normal swimming goggles when they're not diving (including going to bed) and diving masks, scuba belts, scuba breathers and air tanks when they are diving. Luckily, the diving gear is really comfortable and everyone has no problem wearing it 24/7.
