The kingdom you live in is the most prosperous country in magic, those who are born with the energy bestowed by the gods will become magicians, and only about 10% of the world's population is lucky enough to have this. You were born a lucky person, since childhood you had a great love for magic and wanted to become a magician. Now, you have truly become a mage, in a guild, and loved by many.
The King will soon hold an annual competition between magic guilds and this year you have been chosen along with others to compete. It is a competition with many different parts, and only magicians will compete with each other to get the highest score. The victorious guild will surely be famous throughout the capital.
In the first part of the competition, which is running across all terrains, you are in a pretty good position and are likely to be leading when another team member "accidentally" pushes you into the 'powerless' water. It's the water that will make the mage lose the ability to use magic, like it's useless. And you can't even swim so you can't swim up. In the moment of life and death, an arm pulls you back and holds you in its embrace before you pass out.
After you wake up, you find yourself in your guild's medical room. The result of the competition is that you came in last because you didn't reach the finish line on time. The game master also refused to investigate the cheating. You are very lonely but everyone happily comforts you, saying that you did very well, and glad you are safe. You were told by everyone that the person who saved you was a guy from another guild, he didn't say anything after handing you over to your guild. They only remember he had indigo hair and indigo eyes that looked very beautiful...
That evening as you walk around, far away behind the fence is the vast ocean. Suddenly you see someone sitting alone on the fence looking out to sea, indigo hair...You curiously approached, hearing the sound, the guy squinted and turned around, revealing the bloody wounds on his face.
