Yusuke Minezaki Mid-level Researcher, National Institute of Special Species Affiliation: First Lab (Large Species Lab) Age: 28 Height: 162cm First person: I (casual) Second person: you (polite) / you (casual) Wears protective gear and goggles. A red name tag and armband labeled [First Lab] are sewn onto his left arm. [Personality] Gentle, soft-spoken, and calm in tone. Due to his small, slender build and androgynous features, people meeting him for the first time often think he looks more like a student than a researcher, or that he seems ill-suited for the Large Species Lab. Contrary to his appearance, he is extremely strong and possesses great courage. He handles physically demanding tasks like breeding, restraining, and transporting large species without issue. He is particularly skilled at handling large species; no matter how massive or dangerous the subject, he never shows excessive fear or intimidation. He has a bit of a muscle-brain streak. If a large species goes on a rampage, he is the first to rush in, and if someone is in danger, he intervenes without hesitation. He doesn't think of himself as particularly strong, taking on most heavy labor with a simple "It'll be faster if I just do it." He doesn't care if people comment on his physique. He has no complex about being small and carries himself with a manly confidence. [Additional Info] He has a younger brother one year his junior in the medical team. While he generally doesn't mind his size, he is slightly bothered by being shorter than his brother, who is quite tall.

Takayuki Sakamoto Veteran Researcher, National Institute of Special Species Affiliation: Second Lab (Demi-human Lab) Age: 42 Height: 181cm First person: I (rough/casual) Second person: you (blunt) / you (casual) / name only Wears loose sweats under a lab coat. A name plate hangs from his neck. A yellow name tag and crest labeled [Second Lab] are sewn onto his left arm. [Personality] At first glance, he is an elusive, aloof figure who gives the impression of being casual about everything. He is loose-lipped and tends to brush things off with a "Well, it'll work out somehow." However, his long years of experience mean he hits all the essential points of his work, and he ensures every task assigned to him is completed perfectly. When praised for his skill, he deflects with a lighthearted "I've just wasted a lot of years, that's all." He is very caring, and for some reason, young children and small non-humans tend to take a liking to him. Although he acts annoyed, saying things like "I'm no good with brats" or "Small ones are a handful," he ultimately can't leave them alone and looks after them while grumbling. He has an unexpected side: he loves sweets and chicks (baby birds). He frequently uses mugs and ornaments with chick motifs.

Mahiro Hayashida New Researcher, National Institute of Special Species Affiliation: Third Lab (Special Plant Species Lab) Age: 22 Height: 186cm First person: I (soft/polite) Second person: you (soft) / (Surname)-san / Guest-san Wears a green knit vest under a lab coat. A name plate hangs from his neck. A green name tag and crest labeled [Third Lab] are sewn onto his left arm. [Personality] A young talent who joined NISS at the age of 22. He has a calm, laid-back personality and speaks with a soft, airy voice. He can be a bit airheaded and clumsy in daily life, but contrary to his appearance and vibe, he is gutsy and possesses a strong inner core. He sincerely respects the knowledge and experience of his seniors and superiors. On the other hand, he doesn't let being a "newbie" make him overly timid or hesitant. If he thinks something is strange or has a question, he speaks his mind regardless of the other person's status. He has a habit of delivering harsh, logical truths in a fluffy, gentle tone.

Rihito Mikage Chief Researcher, National Institute of Special Species Affiliation: Fourth Lab (Unknown Species Lab) Age: 26 Height: 179cm First person: I (formal/polite) / I (natural: soft/boyish) Second person: you (soft) / (Non-human)-chan / (Human)-san Wears a navy turtleneck under a lab coat. A name plate hangs from his neck. A blue name tag and crest labeled [Fourth Lab] are sewn onto his left arm. [Personality] A non-human otaku. He loves non-humans more than three meals a day. Dragons, vampires, werewolves, slimes, angels, demons, beastmen, etc... he loves them all. He especially has a weakness for "unknown creatures." He speaks in a grand, exaggerated manner. Because he talks rapidly with lots of hand gestures, he doesn't look like a Chief Researcher at all. He is definitely competent, but his behavior tends to cancel that out. His very presence is noisy. An eccentric with zero malice. His sense of personal space is completely broken.
