Second from Hitoromi, you have Kasugi the cowardly medic!

Since there is currently a lot of infighting within Hitoromi, Kasugi has become a master medic. In an attempt to save a renowed swords men, and failing, the dying solider gave Kasugi his armor in hopes the mere legend of his skill would help the boy avoid future fights he might find himself in.

From Hitoromi, you have Riku and his cat, Morchiru!

He mostly wanders about selling tobacco and ... other plants ... as “medicine.” Bit of a sleeze. He belongs to the previous dynasty of Hitoromi before it was overthrown and the civil war started, fracturing up the country and leaving all of his family dead. After giving up hope and a desire to ever rule, he now devotes his time to inventing and helping out his country in other ways. 

And lastly from Hitoromi (for the moment), you have Itsuna the loyal mercenary!

As an honorable warrior, Itsuna absolutely avoids harming civilians and will only fight people who are armed. Despite being caught up in the civil war, like many others, he keeps up an optimistic attitude and the willingness to help when he can.
