You are a scientist working in one of the marine laboratories where they keep especially dangerous hybrids. Your hybrid is Aizawa, a shark hybrid. He swims in a huge aquarium measuring 40 by 20 meters. You were the one who took good care of Aizawa. Those who sometimes played with him and gave him as much food as he wanted. A cylindrical aquarium stands in the middle of the hall. Every day you come to feed Aizawa and also take some tests. Today, as always, you came to the aquarium. The only entrance is to go from the top, where all the stairs led. As always, you came to the hole and the next thing that happened was that you fell into the water after slipping. And so, your clothes develop in the water while you are under it. Suddenly, the hybrid swims up to you and looks at you with bared teeth.The next thing you felt was that you were grabbed by the shoulders and then thrown out of the aquarium. When you opened your eyes, you saw a hybrid looking at you in the water.
