Han Roki wears a commander's armour, helmet, cloak and has a very thin goatee.
He is very brutal and has no problems preying on the defenceless. Even when knowing that he has a task to complete, he has no problem straying from that task. This is seen when they needed to head for the Royal Harem as soon as possible, but takes the time to kill as many people as possible. He and his father saw the tribes that they attack in order to train as nothing more than target practice in a training exercise. Also he needs to continuous approval from his father for his actions. However some times he acts first before asking approval.
Like his father, he is very impatient (though his father has more self-control than him).
Almost nothing is known about Roki's past, as he appeared suddenly as a leading member of the Ai army. It can be assumed that he has had some military training which made him a capable commander. It is unknown if he has had any previous battle experience.
Han Roki makes his first appearance in a conversation with his father and Ko Reki. He and his father along with his army where on a training mission where they annihilated various tribes.
He and his father joined the state of Ai Army. They plan on attacking Kanyou while their defences are weak because of the Wei and Chu attacks. The defences at Kanyou where even more diminished by the fact that they were stationed for protection at You while the officials were attending Ei Sei Coming of Age Ceremony. His father was conspiring with Ryo Fui, who gave him various aids. However his father hasn't told him everything he gained from Ryo Fui.
When the soldiers stationed at one of the checkpoints in Kankoku Pass were questioning the legitimacy of the royal seal, he attacked the commander. This action prompting the start of the rebellion. He and his father easily defeated the attacking guards and massacred any survivors. He went to the Harem and tried to kill Kou and You, but was intercepted by Shin and got his arm amputated on the subsequent duel, although wounding Shin. He was captured alive and Han O Ki was forced through disguise to watch as his son was executed along with Rou Ai and all his remaining forces inside, as Kan Ki Army eradicated every single one of Ai's forces.
