Sister and brother twins, Kōtetsu and Kage are designed to be played together by two players at the same time, but one person could play both parts if you wanted. Either way, they are played together, with the same initiative. THE TWINS are stronger and do more damage when they work together. Kōtetsu stands head-to-head against a monster and Kage sneaks up and flanks the monster. Kōtetsu keeps the monster's attention with one hand on her katana. When Kage hits with his katana, it does damage as if they both attacked and hit. But Kōtetsu must be touching her cursed katana to make the damage increase. 

They are designed as a female samurai and a male assassin; however, you can play them boy-boy, girl-girl, or girl-boy. It's completely up to you. Just remember that they fight as a team and they have ONE initiative. When teamed up, they play at the same time. 

Once, Kōtetsu and Kage were human twins, heirs to a noble lineage in a city steeped in tradition and honor. Their lives took a dramatic turn when, driven by youthful curiosity and a thirst for adventure, they ventured into the lair of a notorious sorcerer. There, they discovered a legendary katana, crafted by the famed swordsmith Hattori Hanzo. Unbeknownst to them, the blade was cursed. In their attempt to claim it, the sorcerer's wrath was unleashed, shattering the katana into shards and transforming the twins into animal-kind:  Kōtetsu into a powerful rhino-folk, and Kage into a nimble capuchin monkey-folk. Ashamed and seeing their transformation as a failure, their father banished them from their home, decreeing they could only return once the curse was broken.

Now outcasts,  Kōtetsu and Kage were forced to rely on each other, their contrasting personalities and skills becoming their greatest strength. They learned to navigate a world that now saw them as monsters, their shared purpose driving them forward. Their quest led them to the Arcadian Order of Baeron, a group dedicated to fighting evil and protecting the innocent. Finding solace and purpose in the Order's mission, they vowed to use their unique abilities to combat the forces of darkness, all while searching for a way to undo the sorcerer's curse, either by destroying her or returning the reforged katana to its secret lava forge.
