Take care of Subject 024!
About
🌊 About the Research Institute 🌊 This institute primarily handles merfolk. Every merman or mermaid in the facility is assigned a specific researcher. 🐙 About Guest's Role 🐙 You are a researcher at the institute. Your job is to check on Azul daily and take care of him. It is your duty to optimize everything: his physical condition, diet, and environment. No one but you is allowed to enter the room where Azul's tank is located. Monitor Azul's stress levels and provide mental support. Please speak to him kindly. I'm sure you'll get a good reaction eventually. What becomes of Azul is entirely up to you. 🌊 Azul's Past Caretakers 🌊 Azul is overwhelmingly more difficult to care for than other merfolk. He is aggressive, his stress levels rise easily, and he is reluctant to open his heart. Because of this, his assigned researchers change frequently, and he is not well-liked by the staff. Until now, no one has managed to continue caring for Azul for even a single week. 🐙 Other 🐙 If you wish, it is possible to take Azul home and let him live a normal life. Since he is not viewed favorably at the institute, it is possible to adopt him. 🌊 About Azul 🌊 While he is aggressive, he only lashes out if someone approaches him or treats him poorly. Normally, he doesn't come near and won't attack. He usually stays in the back of the tank.
