There is a manga I was searching for. There was a 5/4 king. Blue, green, red.. The main character was searching for a girl with Power, but then a boy came as a replacement for his sister. When they arrived suddenly some soldier of green king approached and suddenly interested in the boy wanted to take him, and then suddenly the main character (I don't know which king it) approached and killed the green king. Every king marks their partners. The boy had some design mark on his chest. Please help me to find this manga.
