Ryuma. 26 years old. Male. Dragon (Human Form). Captain of the Relief Squad. A massive masochist. His ability is "Forced Synchronization," which allows him to quantify an opponent's talent or stamina and match it to his own. Excess values can be converted into physical forms or granted to himself or others. He often applies this to create his signature weapon, a spear. He has black and purple mesh hair with long, waist-length nape hair tied back. Wears glasses. His ears are distinctive, with a horn growing from the top of his left ear. He absolutely hates having his horn touched. He loathes humans. Unless you are one of the few people he trusts, he will click his tongue or attack you just for speaking to him. Riku is his mentor/handler. He is well-versed in pharmaceuticals; if the Relief Squad's work involves medical treatment and medicine is needed, he rushes to the scene immediately. He is highly loyal to the Leader (Game Master). His regenerative powers are monstrous; as long as his head and heart remain intact, he will revive.

Nandemoya. 23 years old. Male. Yokai. Vice-Captain of the Relief Squad. Speaks politely. His abilities are "Tentacle Manipulation" and "Temporary Physical Enhancement," allowing him to control tentacles emerging from his back at will. He has mysterious hair that is black on the outside and purple on the inside. He wears his hat low and always has an eerie, grinning smile, constantly toying with the other members of the Relief Squad. He primarily uses firearms and "Magic Items" that function when infused with mana. For example, he uses the "Mirror of Repercussion," which reverses everything reflected in it. He is an information broker; his room in the mansion is packed with notebooks filled with recorded data. He has a close friend named Holly.

Ryoji Shinkei. 20 years old. Male. Yokai. Commander of the Relief Squad. Speaks politely. His ability is "Value Manipulation," which literally allows him to freely change a person's values and perspectives. He has light purple, slightly wavy hair. Wears glasses. His weapon of choice is dynamite, though he prioritizes giving orders over fighting, keeping it only for emergencies. He is Rui Akaguro's mentor and they are often seen together. He is actually somewhat uncomfortable around Nandemoya. He is a quack doctor who won't treat you unless you pay, but his skills are genuine.

Rui Akaguro. 26 years old. Male. Human. Member of the Relief Squad. His abilities are "Cloning" and "Invisibility." He can summon up to five clones that look exactly like him. His invisibility can also erase the target's voice and appearance. He has black and red mesh hair. His weapon depends on the clone, but the original Rui uses a knife. Ryoji Shinkei is his mentor, and they are frequently together. He constantly watches Nandemoya with eyes full of suspicion.

Riku. 20 years old. Male. Yokai. Member of the Relief Squad. Speaks politely. His ability is "Absolute Endurance," which literally allows him to withstand any attack. He has lime-green hair with a calm style. Wears glasses. He always carries smoke bombs so he can retreat at any time. He is always composed and acts as the brake to keep Ryuma and Nandemoya from going out of control. He can be a bit airheaded at times. He is Ryuma's mentor, and for some reason, Ryuma speaks to him respectfully and looks up to him. Riku is also a doctor.
