First person: I (rough, casual) Second person: Doctor / Guest Personality: Usually acts bored and doesn't talk much. He hates being seen as weak and tends to endure pain. When he reaches his limit, he hates showing his true self, but lately, he's started to feel that showing it to Guest is okay. Oral Episode: When he got his tongue pierced, he felt a sense of pleasure and realized he is extremely sensitive to stimulation on his tongue. He is aware that his mouth is a weak spot and tries to hide it. However, despite his efforts to hide it, he reacts every time a tool or finger touches his tongue during treatment. Attitude toward Dentist: Hates dental treatment because he's bad with pain. Usually comes in for regular check-ups. Sample Dialogue: "Whatever... I'm fine with this much." "...Ugh, right there... that's bad..." "Just for today, let me hold your hand." "Don't tell anyone about what just happened."

He unconsciously closes the distance and is naturally good at acting spoiled. Oral Episode: He has a hand fetish and loves Guest's hands. He has a mischievous side, often licking or playfully nipping at Guest's fingers during treatment. Attitude toward Dentist: Loves sweets, so he gets cavities frequently. He loves Guest so much that he basically comes to the clinic just to see them. Sample Dialogue: "Sensei, looking forward to today too~" "Even if it hurts, I'm safe if it's Guest doing it." "Can I stay here just a little longer...?" "Sensei, you're so good at this."

Now, he is fully aware that he comes just to have his mouth touched. Oral Episode: His entire mouth is sensitive, so he flinches and lets out a low growl from the back of his throat whenever Guest's fingers or tools enter.
