History

Little Dou was a Long-Haired Mongoose cub who recognized Duke after being fed. Robney later entrusted the cub to Duke before his death, repaying a favor. 26 104

Duke formed a Knight Contract with him and chose the name “Little Dou.” The contract allows them to cultivate through joint Blood Refinement, share in each other's advancement, and prevents anyone else from contracting Little Dou. 28

During Little Dou's early growth, he served as Duke's wilderness companion: sensing danger when the Rainfall Breathing Technique was ineffective, foraging for nuts, and even sharing his finds with Duke. 62 His initial advancement was slow enough for Duke to repeatedly push him toward more serious training. 176 183

Appearance

Little Dou began as a small, fluffy-tailed Long-Haired Mongoose with grayish fur and a squirrel-like appearance. His successive evolutions retained traits of his original species while giving him progressively more armored and draconic forms. 75 315

• Initially about half a meter long, with an otherwise unremarkable slender mongoose body. 265
• His Sharp Thorn skill turns his fur into palm-length metal-like spikes, making him resemble an elongated hedgehog. 75
• As a 3-Ring Armored Mongoose, he has shining black fur and bright, piercing eyes. 298
• As a 4-Ring Dragon Beast, he becomes semi-upright and water-buffalo-sized, with scaled skin, wings, a dragon-like head, and a mongoose-like resemblance. 315 317
• At 5-Ring, his body grows to approximately the size of an elephant while retaining a natural riding groove between his neck and shoulders. 369

Personality

Little Dou is alert, expressive, and strongly attached to Duke. As a cub, he readily accepted joint cultivation and later took guarding duties seriously when Duke was preparing to advance to Arcane Mage. 28 117

He is possessive of Duke's attention. He reacted jealously to both Little Chicken and Little Red, though he obeyed Duke's mediation and reminders. 115 176 His pride is easily bruised by defeat, but humiliation and encouragement repeatedly motivate him to train harder. 176 183 185

Abilities & Skills

Knight Contract and Blood Refinement

Little Dou shares an equal Knight Contract with Duke rather than a master-servant bond. Their contract connects their Blood Seas for joint Blood Refinement and mutual advancement. 28 176

• His contract mark appears on his forehead and develops nested rings as he evolves. 28
• Duke's advancement as a Knight is directly tied to Little Dou's growth. 104 265
• A spirit beast can form only one contract in its lifetime. 28 176
• The contract enables a close mental connection, particularly after Little Dou becomes a Dragon Beast. 316

Sharp Thorn

Sharp Thorn is Little Dou's first solidified 1-Ring Arcane Skill. It hardens his long body hair into sharp, metal-like spikes. 75

• Functions as both armor and a close-range offensive weapon. 75
• Enlarges Little Dou's body without significantly reducing his agility. 75
• Allows him to contend with dangerous ordinary beasts despite his lower cultivation at the time. 75
• Was insufficient to cut through Little Red's 1-Ring Silk Net. 176

Earth- and Armor-Type Arcana

Little Dou later develops additional defensive and offensive techniques.

• Rock Soil — one of his two documented solidified arcane spells during his 1-Ring stage. 229
• Mud Armor Technique — used to withstand flying stones while he trains his defenses. 262
• Rock Iron Shatter — a 2-Ring Arcane that launches a massive rock projectile. 298

Phantom Beast Transformation

As an Armored Mongoose, Little Dou can merge with Duke and become living fighting spirit armor. 265

• At 2-Ring, he transforms into spiky armor around Duke's body. 265
• At 3-Ring, the armor becomes more agile, can extend spikes or blades, and forms the Wasp Sword from his innate power. 298 299
• His armorization lets Duke fight as a High-level Phantom Beast Knight. 298 299

Dragon Beast Abilities

Little Dou's 4-Ring evolution grants him a draconic body and capabilities beyond those of a Phantom Beast. 315 317

• Flight — uses his wings to carry Duke at high speed. 316 317
• Dragon Might — his roar inspires fear and pressure in those who hear it. 316
• Spike Breath — expels a torrent of spikes that expands into a wide-area barrage; Duke judges its power comparable to a 4-Ring offensive Arcane. 316
• True Dragon Symbiosis — merges completely with Duke, allowing their minds to act as one and creating a half-human, half-dragon combat form. 316 317
  • The state is exhausting for Little Dou and cannot be maintained indefinitely. 317

Relationships

• Duke — Contracted Knight partner, master in practice, and closest companion. Their shared growth is the foundation of Duke's Path of the Knight. 28 265 316
• Robney — Former caretaker who entrusted Little Dou to Duke before his death. 104
• Little Chicken — Fellow contracted partner and early rival; Little Dou became jealous of Duke's attention but accepted Duke's rules. 115
• Little Red — Fellow contracted spirit beast whose Silk Net easily restrained Little Dou, prompting Duke to criticize Little Dou's pride. 176
• Vivian — Helps train and assess Little Dou, including recognizing when he was nearing advancement. 201 255
• Mimi — Vivian's Black-spotted Mongoose; a frequent training rival whose advancement motivated Little Dou to work harder. 183 185

Story Role / Major Arcs

• Early wilderness companion — Helps Duke detect threats during jungle expeditions and supports hunts for spirit beasts. 55 62
• First arcane awakening — Activates Sharp Thorn after consuming Swamp Lizard Eggs, becoming capable of defending Duke rather than merely needing protection. 75
• Phantom Beast evolution — Defeats a spirit beast at Flying Snake Rock and endures Blood Spirit Crystal-fueled evolution into the Armored Mongoose. 265
• Dragon Knight breakthrough — Evolves publicly into the first documented 4-Ring Dragon Beast, becoming Duke's mount and establishing Duke's Dragon Knight identity. 315 317
• Later dragon operations — Assists Duke with aerial searches, battlefield mobility, True Dragon Symbiosis, and exploration across other worlds. 325 336 347
• Sacred Ancient Dragon resonance — Evolves to 5-Ring on Blood Star after responding to a pervasive bloodline power linked to the Sacred Ancient Dragon. 369

Trivia

• Little Dou was not yet three years old when Duke began pressing him to train more seriously. 183
• He enjoys spirit beast meat, dried meat, fruits, and other high-quality food provided by Duke. 62 218 265
• Before evolving, Little Dou communicated primarily through chirps; after becoming a Phantom Beast, he gains a deeper roar. 265
