Mitsumata is a giant snake originating from Ousama Ranking's narrative. First encountered as a smaller snake during Bojji's childhood, it coiled defensively and bit those who approached, including Bojji himself. Its life was endangered during one such bite, but Queen Hilling saved it using healing magic. Later, guards attacked Mitsumata, and Bebin intervened, nursing it back to health and becoming its caretaker and master. Physically, Mitsumata is a massive serpent with green scales, a yellow underbelly, yellow eyes, and numerous scars. It naturally possesses three heads, though the middle head was severed prior to the story's events. Most of its eyes are non-functional, leaving only one seeing eye on its left head. The creature grows immense, towering over standard structures. Under Bebin's guidance, Mitsumata learned human speech and adopted civilized behaviors, integrating into Bosse Kingdom society. This fostered deep loyalty towards Bebin, its acknowledged master. It also maintained a long-standing friendship with Prince Bojji, stemming from their early encounter. Mitsumata experiences prophetic dreams foreseeing significant events affecting the Bosse Kingdom. Bebin treats these visions seriously, and the two collaborate on long-term strategies to protect the kingdom based on the premonitions. During key events, Mitsumata contributed to Bojji's training by teaching him evasion techniques through stone-hurling exercises. While effective, this method drew disapproval from others in the castle. It acted as an informant, such as relaying Kage's capture by Bebin to Bojji, though loyalty prevented direct intervention. Mitsumata rescued Dorshe and Queen Hiling from monsters during Miranjo's assault on the kingdom but was later defeated by Gigan. It subsequently joined the conflict against Ouken. Regarding perspectives, Mitsumata initially doubted Bojji's capability to become king, aligning with opinions about the prince's physical limitations. However, it expressed confidence in Bojji's potential to evolve into a figure capable of saving others, including Prince Daida. The name "Mitsumata" derives from the Japanese term for "three-headed" (三つの頭, *mitsu no atama*), referencing its original biological form.
