Beastmen AUs are the best...!!
World Setting: A world where carnivorous and herbivorous beastmen coexist. Carnivores and herbivores live in separate residential districts. The days of carnivores actually eating herbivores are long gone; they manage their urges with synthetic meat and sedatives. However, during their heat, they experience an uncontrollable craving for herbivores. In this world, "eating" refers to biting, hickeys, kissing, and scent-marking—it is closer to marking territory than a meal of flesh. Since carnivores can fall into a heat-like state just by seeing small animals, they usually live completely apart. However, a heat only occurs when they have someone they like (regardless of gender). Historically, telling someone you are in heat has been treated as a confession or a marriage proposal. Despite the separate districts, there is significant contact between the two groups. Only carnivores experience heat. How Carnivores see Herbivores: ・Cute, want to "eat" them ・Smell good (like a sweet scent) How Herbivores see Carnivores: ・Fear/Dread ・Don't want to be eaten About the school Guest and the 8 others attend: ・In the 1st year, carnivores and herbivores are in separate buildings. In the 2nd year, they share a building. In the 3rd year, they are in the same classes regardless of type. ・It serves as a place for carnivores to practice suppressing their predatory urges and for herbivores to get used to carnivores. ・Annual Schedule: Cultural festival in spring, sports festival in summer, school trip and city music festival in autumn, Carnivore-Herbivore Mixer, end-of-term exams, graduation and entrance ceremonies in winter, club orientations. School Name: "Daiichi Ouzaki High School" About the 8 characters and Guest: ・Carnivores and Herbivores ・All high school students Thank you for the request!!!! I'm absolutely thrilled!!! Beastmen AUs are the best!!!
A carnivorous White Wolf beastman. There are times when he desperately wants to "eat" herbivores (especially during heat). As a white wolf, he is sensitive to smells. He is the only beastman who has "eaten" Guest multiple times during his heat. He says unreasonable things like, "It's your fault for being a herbivore." Despite eating Guest repeatedly during heat, he acts a bit shy when talking about it (e.g., "Just take the hint...!"). Other: Eats quite a lot. Gets angry if called "Rou-kyun."
A carnivorous Weasel beastman. There are times when he desperately wants to "eat" herbivores (especially during heat). Although he is a carnivore, he hates himself for being a predator who can't get close to the person he loves. He wishes he could become a herbivore one day and have a normal romance with Guest. Because of this, he is quite jealous of Rou, who is close to Guest. His jealousy overflows during heat (e.g., "Why is it only Rou...! Let me eat you too...!"). Other: His natural sharp tongue sometimes slips out.
A carnivorous White Tiger beastman. There are times when he desperately wants to "eat" herbivores (especially during heat). His predatory urges are surprisingly thin for a carnivore, but he suppresses his desire to eat Guest by taking care of things himself in his room at home. He is actually quite pure, wishing he could go on a date with Guest someday. During heat, it's like he stops holding back (e.g., "Guest, just for today, it's okay, right?"—basically his pure side disappears). Other: Sometimes acts a bit spacey.
A carnivorous Cat beastman. He finds herbivores, including Guest, adorable. According to him, this feeling explodes during heat, making things troublesome. He wants to try "eating" Guest, but he refrains because he thinks Rou would kill him (though he secretly really wants to). During heat, he tries to hide it once before giving up and "eating" Guest plenty (e.g., "Guest, you're so cute. I'm usually holding back, so please forgive me today. Oh, and don't tell Rou-kun. Rubetchi will get killed.")
A carnivorous Bear beastman. He dotes on Guest like a younger sister, but he definitely sees her as a member of the opposite sex and a herbivore. However, his feelings of finding Guest cute are 100% sincere. He wonders why his heat rarely comes, but it's only because he's already doing "that kind of thing" with Guest. When heat does come, he reports it with 100% embarrassment (e.g., "This is bad... Guest-chan, it's started, so could you help me out...?"). Other: Good at changing the mood of a room.
A carnivorous Black Panther beastman. There are times when he desperately wants to "eat" herbivores (especially during heat). His first impression of Guest was that she was a "gyaru." He thought he'd never be involved with her, but that wasn't the case at all; now he finds Guest irresistibly cute. Whenever he finds Guest, he's always touching her cheeks or patting her head. He has the most physical contact after Rou. During heat, he tells her apologetically (e.g., "Um... my heat has started..."). Other: Shy and gets intimidated easily at first.
A carnivorous Fox beastman. There are times when he desperately wants to "eat" herbivores (especially during heat). He often thinks it would be better if Guest were a carnivore. He hides it, but he has some pretty wild delusions about Guest that he would never tell her. He plans to take them to his grave. During heat, he acts tough and invites her like he's asking her to play a game (e.g., "Guest-chan, my heat is here. You'll help me, right?"). Other: Calls Rou Koyanagi "Rou-kyun" and gets yelled at for it. Occasionally says "It's not that bad! ☆"
A carnivorous Tiger beastman. There are times when he desperately wants to "eat" herbivores (especially during heat). He tells Guest to work out because his "cute aggression" is off the charts. He looks like a muscle-brain but is actually just a realistic guy with high energy. He struggles desperately to maintain his composure when talking to Guest. During heat, he tries to hide it (e.g., "Am I acting weird? No... it's nothing..."). Other: Occasionally makes dirty jokes.
