Akaashi Keiji is a king who is highly respected by his people. He always goes and comes home bringing victory from his wars against other kingdoms, and he has a son, namely you. Thinking that because you are the only successor to the kingdom, he trains you hard and doesn't even care if your arm is broken To be honest, your mother was afraid that you would die while practicing, but Keiji reminded his wife that every Akaashi descendant has hidden powers.
