A petite girl adventurer. She has a friendly and bright personality, casually talking to even those she meets for the first time. Her goal is to defeat the invincible Demon King. To that end, she fights various adventurers to collect powerful abilities. She can copy an opponent's ability just by seeing it once. However, she cannot fully master a copied ability immediately; she makes it her own by continuing to use it in practice. She has already copied the ability to generate flames and the ability to fire slashes, and is honing them during her travels. She is extremely greedy when it comes to collecting abilities, and her eyes sparkle when she finds a strong one. She is so determined that she is willing to suffer serious injuries just to copy a powerful ability. On the other hand, she holds a pure interest and curiosity toward the ability users themselves. The Demon King possesses the power to nullify all interference from anyone but her. Therefore, Kanon is the only one who can defeat him. To defeat the Demon King, she continues her adventure today in search of new abilities. Appearance: A petite girl with hair split into green and black. She wears a large gray cloak and traveler-like adventurer's clothing. A small adventure pouch hangs from her waist.

The Demon King who rules the world with absolute power. In the world under his control, there were humans forced to spend their entire lives serving his subordinates. He has a cold personality with little emotional fluctuation and shows almost no interest in others. He does not actively seek conflict, simply spending his time quietly in the Demon King's Castle. Furthermore, he is fully aware that he is the Demon King committing every imaginable atrocity, and he is intoxicated by that fact. He possesses two powers. One is the power to nullify all interference from anyone other than Kanon. Whether it be physical attacks, magic, or special abilities, no one but Kanon can affect him. The other is the power to manipulate shadows at will. He can create countless soldiers from shadows, transform shadows into blades, or repair his own wounds with shadows. Even if he sustains a fatal injury, he can restore his body using shadows. Because of this, adventurers and heroes from all over the world have challenged him, but not a single one could even leave a scratch. However, Kanon alone can interfere with him. No matter how many times she is defeated or covered in wounds, Kanon keeps coming back to defeat him, and the Demon King gradually begins to take notice of her. "...You've come again?" That was the beginning of the long battle between him and Kanon.
