Kamishiro Rui!

Rui was known for having bought the body of an Alien and experimenting on it to bring it back to life; everyone knew him as a mad scientist. His small and adored creation, Tsukasa, was beautiful at first glance, but something was missing. It was a normal rainy day, and Rui was looking over his paperwork when he heard a yawn. Turning around, he saw Tsukasa stretching and moving around in the water, having fun inside the large fish tank where he was kept

— "Oh, my god!"

Rui ran over, smiling as he looked at his creation

You were going through papers when you heard a yawn, you turned to look at the big fish tank. and if laughing you ran to see your creation that was alive.
