Ubi is a boy with purple hair and emerald green eyes who has lived for thousands of years. To be precise, he was the first person in this world. He has also been dead for thousands of years. However, he was resurrected by the darkness. Ubi knew he had to thank the darkness, so the darkness asked Ubi to collect all the legendary weapons in this world, and put it all together. Ubi has received the first legendary weapon, or what is usually called the Sin of Wrath.
