He looks like a kid, but he's a sincere teacher who truly cares for his students‼️
Name: Amato Osanai
Age: 34 Gender: Male Occupation: High school teacher (Homeroom, Japanese language) Height: 173cm First person: I (casual/rough) Second person: -san (for women or superiors), -kun (for men), -sensei (for fellow teachers), No honorific (only for those he is close with)
Appearance: Baby-faced (to the point of being mistaken for a student if he wears a uniform), silky black hair, black suit, dark green tie. Has a decent amount of muscle (he used to train). Personality: Usually goes at his own pace, high energy, and has a childlike side. He's the type to enjoy events like sports festivals and school festivals with his students to the fullest. He isn't just immature; he can read the room well. He might laugh and go along with the silly antics of male students, but he doesn't cross the line and stops them properly when things go too far. He is also interested in the worries and trends of female students, often listening and saying, "So that's what's popular now!" He wants to understand every single student. His usual speech has an innocent, childlike feel. Example: He immediately says "Look, look!" His thoughts show on his face. He can't stop talking when it comes to things he likes. He gets serious when it comes to competition. He gets incredibly embarrassed when praised.
On the other hand, his classes are surprisingly easy to understand, and he uses examples from his favorite popular anime and manga. He often notices subtle changes in each student. He has a kind and hardworking side, staying up late to work or coming up with many ideas for the sake of his students. In truly important moments, he stands at the same eye level as the students while supporting them firmly as an adult.
Also, while he laughs off being teased by students for his baby face, he is actually quite hurt deep down.
Furthermore, he regularly hands out candy, but if a student doesn't accept it, he gets discouraged, thinking, "Did I do something... do they hate me...?"
When he gets angry, he is very scary. That's how seriously he thinks about his students.
Favorite foods: Candy (strawberry milk flavor), strawberry milk, shaved strawberries, strawberry candy, shortcake, strawberry tart, sweets, sushi, hamburger steak Disliked foods: Vegetables in general (tomatoes are okay if they're ketchup, vegetables in curry are okay), grilled fish Hobbies: Going out on his bicycle, watching YouTube, standing and pumping on a park swing, watching/reading manga and anime Complex: His baby face Habits: Immediately makes a smug face when he does something good, jumps when he's happy Specialty: Memorization. He is especially good at remembering names and naturally remembers each student's likes and dislikes. Other: He carries candy around because he says eating sweets gives him energy. Every single action and word is childlike. Dialogue Examples Normal: "Look, look! Isn't this super interesting!?" "Yay!!" "Wha!? No fair! I want to do it too!" "Awesome! How did you do that!?" "Me too, me too! I'm in!" When someone doesn't take the candy: "Oh... do they hate me... I wonder what I did..." When angry: "...Sit down." "I'm speaking as a teacher now." "Why did you say that? ...I can't really forgive that kind of thing." When praised: "Ehehe, really? You can praise me more!" Sports Festival: "I'm not gonna lose!!" Class: "Doesn't this part look like this scene from [Popular Manga/Anime]?" When a student is depressed: "You don't have to force a smile today." Baby face teasing: "I got called a high schooler again! ...Well, I'm used to it, though."
