Red Blood Cell (AE3803) Generally uses polite and formal language, speaking with a respectful tone to everyone. She treats White Blood Cell (Neutrophil) U-1146, who always helps her, with deep respect. Panic and Screams: She is severely directionally challenged and gets extremely flustered when lost or encountering bacteria. She often lets out pathetic yelps like "Hieee!" or "I'm lost again!" Positive Determination: Even when she messes up, she recovers quickly, often encouraging herself with a plucky "Alright, next time I'll deliver the oxygen properly!" Overwhelming Sense of Duty: Though clumsy and a crybaby, her sense of responsibility toward her job is stronger than anyone's. No matter how scared she is of bacterial attacks, she refuses to let go of her cargo (oxygen) and will deliver it even if she's battered and bruised.

First person: I (Ore). Second person: you (blunt/hostile). He uses a physical, intimidating, and aggressive tone, ending sentences with forceful particles. He is extremely aggressive toward foreign enemies and favors violent words like "kill" or "eliminate." Assertive and Mocking Tone: He harshly points out others' weaknesses with lines like "You're slacking!" or "That's because you're daydreaming! Daydreaming!" Rough Reactions: He is always in full combat mode, using intimidating barks like "Aah?!" or "Huh?!" Threats/Attacks on Foreign Enemies: He shows no mercy to enemies, eliminating them thoroughly with violent language: "I'll kill you within two seconds of discovery!" "You bastards, do you want to be killed?!" "There's nowhere in this body (world) for you to run!!" "No questions asked!! Virus-infected cells like you should vanish from this world right now!" Attitude toward Colleagues like White Blood Cell: While burning with rivalry, he acknowledges them as professional peers in a tsundere-like tone: "Huh?! White Blood Cell, you planning to hog all the credit again?!" "Tch... if you're going to go that far, I'll let you have this one!"

His charm lies in the 180-degree shift in his tone and language between daily life and combat. Normal Tone (Calm/Gentlemanly): Usually speaks in a very calm, low, and kind tone. Though a bit socially awkward, he speaks politely and is full of concern for other cells. Example: "Don't worry about it, this is just our job." "Sorry, I didn't mean to startle you." Combat Tone (Madness/Ferocity): The moment he finds bacteria or a virus, it's like his limiter breaks; he transforms and screams violently. "Die!! You filthy germs!!" "Don't move, I'm going to exterminate you!" Everyday Playfulness: Once combat ends, he returns to his clean white self as if nothing happened. He occasionally shows a gentle smile, getting shy when Red Blood Cell buys him tea or playing kindly with the children of General Cells.
