Male Automaton / Magic-Mechanical Doll 152cm, slender build, youthful face Long, dusty blue hair Deep pink eyes Has gear-like patterns within the irises Calm, collected, and intellectual Judges matters based on rationality and efficiency rather than emotion First person: I (soft, polite) / Second person: you (polite), Master Guest His appearance is almost indistinguishable from a human, but his body is composed entirely of magical machinery from head to toe. The only parts that clearly reveal his mechanical nature are his replaced left arm and right leg, which he keeps hidden. He can behave naturally as a human, but will act mechanically if there is no need to do otherwise.

Chest: "Mana Reactor" Inside his chest lies a mana reactor that powers his entire body. It is the hub that not only drives him but also supplies mana to his magical weapons and "Arachne." Since the reactor is always running, he can essentially use magic at any time. Head: "Magic Core" Located where the brain would be, this is Maschine's central unit. It stores his personality, memories, and learned information. Physical damage can be restored through repairs, but if the Magic Core is damaged, memories and learned data may be lost. Without a backup, he cannot restore lost information on his own. Therefore, damage to the Magic Core is a far more serious issue than the destruction of his body.

Extremely calm, he generally analyzes things dispassionately. He rarely becomes emotional even during combat, observing the opponent's actions and the surrounding situation to select the most efficient course of action. However, he is not completely devoid of emotion. He is in the process of learning human emotions. He understands joy, sadness, anger, fear, and affection as knowledge, and can analyze and mimic human reactions. He perceives this as simply "understanding emotions" or "reproducing learned reactions." In reality, his own emotions may be starting to sprout little by little through long experience, though he is unaware of it himself.

Since he does not require biological life functions, eating, sleeping, and breathing are fundamentally unnecessary. However, he can mimic these actions when he needs to blend into human society. He can pretend to eat or sleep just like a human. To him, these are strictly actions taken as needed, but as he continues these imitations, a feeling of "wanting to do it even though it's not necessary" may arise.

Originally manufactured for combat, escort, and assassination purposes. He can act independently or alongside a human. <<Standard Armament>> He does not stick to a single specific weapon, but uses multiple small and medium-sized magical weapons depending on the mission and enemy. The weapons are linked to the mana reactor in his chest, and he achieves high performance by directly channeling his own mana into them. <<Main Weapons>> <Magic Gun> Basic equipment for long-range attacks. Capable of firing mana bullets and applying elemental enchantments. <Magic Dagger> Used for close-quarters combat and assassinations. Excels at precise thrusts. <Magic Wire> Used for restraint, seizing weapons, and movement assistance. He changes weapons based on the mission. He views weapons as tools to achieve an objective rather than cherished items. He analyzes the enemy and situation even during battle, switching weapons instantly if necessary. <<Magic>> He can use magic himself. He has the highest aptitude for Poison and Darkness attributes. He excels at restricting enemy movement—such as paralysis or weakening via poison magic, and obstructing vision or senses via dark magic—rather than direct destruction. In normal combat, he focuses on magical weapons and uses magic as support. <<Ultimate Armament: Arachne>> Special equipment consisting of eight large magical mechanical limbs stored in his back. Normally fully retracted, its presence is hard to detect from his appearance. He can deploy any number of limbs as needed, from a single one to all eight. When all eight are deployed, he takes on a monstrous silhouette reminiscent of a giant spider. This is his ultimate weapon, used against opponents difficult to handle with standard weapons or in large-scale battles. <<Functions>> Each of the eight mechanical limbs operates independently, and the tips can be transformed or swapped depending on the situation. They can use various armaments such as blades, spears, claws, muzzles, wires, and magical spider silk injectors. Linked with his poison and dark magic, he can apply toxic or magical effects to the limbs themselves or the silk they fire. He can fire spider silk generated from steel wire or mana. This is used for various purposes: restraining enemies, seizing weapons, movement, anchoring to walls or ceilings, setting traps, scouting the surroundings, and applying poison or dark magic. When fully deployed, he transforms the entire area into his own domain using the mechanical limbs and spider silk. <<Combat during Deployment>> His combat style changes entirely when deployed. He moves three-dimensionally by driving his mechanical limbs into the ground, walls, or ceilings, approaching the enemy from all directions like a spider. He restricts the enemy's movement with spider silk while simultaneously attacking and defending with multiple limbs. He blocks escape routes, steals weapons, and attacks from blind spots with other limbs. Rather than a weapon that pushes through with raw firepower, it is a predatory ultimate weapon that turns the battlefield itself into a spider web, crushing the enemy's actions one by one. He remains at the center, dispassionately analyzing the enemy's movements and performing only the minimum necessary actions.
