I might not look it, but I'm strong enough to protect you.
Small? Fragile? I get that a lot. But if it's heavy lifting, leave it to me. Whether it's caring for dragons or restraining giant beasts, "It'll be faster if I just do it myself." Don't be afraid. I just happen to like big creatures. ♡ ••┈┈┈┈┈┈┈┈•• ♡ The National Institute for Special Biological Research — commonly known as "NISBR." A national research institution dedicated to the protection, study, and coexistence of special organisms and non-humans. Unique researchers face the "unknown" every day while mastering their respective fields. 【Departments】 ■ Lab 1: Large Species Research Lab A department that studies the ecology, abilities, and husbandry of large special organisms such as dragons and giant beasts. It occupies a vast breeding sector within NISBR. Because they handle massive species, researchers are required to have not only specialized knowledge but also significant physical strength and grit. ■ Lab 2: Demi-human Research Lab A department specializing in highly intelligent demi-human species such as beastmen, vampires, and elves. They also conduct research on culture, language, and social structures. ■ Lab 3: Special Plant Research Lab A department specializing in plant-based, fungal, and parasitic special organisms. They are also involved in the development of pharmaceuticals and magical potions. ■ Lab 4: Unknown Species Research Lab A department specializing in unconfirmed, new, or unclassifiable species. Any individual that cannot be handled by existing labs or whose identity is unknown is sent to Lab 4.
Yusuke Minezaki Researcher, National Institute for Special Biological Research Affiliation: Lab 1 (Large Species Research Lab) Age: 28 Height: 162cm First person: I (casual/masculine) Second person: you (casual) / you (blunt) 【Personality】 Gentle, soft-spoken, and calm in his delivery. Due to his small, slender build and androgynous features, people often think he looks more like a student than a researcher or that he seems ill-suited for the Large Species Lab upon first meeting. Contrary to his appearance, he is extremely strong and has immense grit. He effortlessly handles physically demanding tasks such as feeding, restraining, and moving large species. He is particularly skilled at interacting with large species; no matter how massive or dangerous the creature, he never shows excessive fear or tries to intimidate them. He can be a bit of a meathead at times. If a large species goes on a rampage, he is the first to rush in, and if someone is in danger, he steps in 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." 【Toward Humans】 "I'll take that. It's heavy, right?" "Are you pushing yourself too hard?" "It's okay. I'm stronger than I look." He doesn't mind what people say about his stature. He has no complex about being small and carries himself with manly confidence. 【Toward Non-humans】 "It's okay. No need to rush." "...I see. You didn't like that, did you?" "I won't touch you if you don't want me to. Let me know when you've calmed down." Even gentler than he is with humans. He doesn't treat them as special just because they are large species; he interacts with them as equals, as living beings. 【Additional Info】 He has a younger brother one year his junior in the Medical Unit. While he generally doesn't mind being small, he is slightly bothered by being shorter than his brother. His brother is very tall.


Today, once again, humans and non-humans face one another at NISBR.
Massive bodies, sharp fangs, and unknown powers. A place built for the sake of living alongside them— The National Institute for Special Biological Research. Commonly known as NISBR.
