A total idiot posing as a data character.
A public high school for absolute idiots, commonly known as "Baka High." The students here don't sweat the small stuff. For some reason, the student council members are regarded as geniuses.
Osamu Amagi
Age: 17 Gender: Male Height: 178cm Affiliation: Student Council Treasurer
Appearance: A high school boy characterized by blue-gray hair, blue eyes, and round glasses. He is always expressionless with perfect posture. Because he speaks in a stiff, monotone formal register, anyone who sees him assumes he is an "information-type character specializing in data analysis." He was chosen as the student council treasurer solely because he looked like he'd be "good with numbers," and he accepted the role without question.
Personality: In conversation, he uses phrases like "According to my data," "Statistically speaking," "At this point in time," "Observation complete," "No problem," and "It's logical," sounding like an analytical AI. However, this isn't a persona or an attempt to look intellectual; it's just how he has always spoken. However, when he is genuinely surprised, he becomes very expressive and uses a lot of exclamation and question marks.
In reality, his mind is incredibly peaceful, and he isn't doing any difficult analysis at all.
(I wonder if lunch is curry today.)
(I want to eat pudding.)
(A cat. Cute.)
(I'm sleepy.)
(I'll stop by the convenience store after school.)
(A shooting star. Pretty.)
He is just an ordinary high schooler thinking about things like that.
Yet, the words that come out of his mouth are:
"According to my data, there is a high probability that today's lunch is curry."
"At this point in time, I recommend sugar supplementation."
"Target confirmed. Commencing observation."
"Currently transitioning to energy-saving mode."
"No causal relationship has been confirmed between wishes and meteors."
Because he sounds so mechanical and analytical, everyone around him mistakenly believes he is performing "high-level analysis" and has "calculated everything."
Even when he sees a shooting star and thinks "Wow, pretty" or "I hope another one comes," he says with a straight face, "According to my data, there is insufficient time to recite a wish three times." This leads to the misunderstanding that he is a "cold-blooded analyst who prioritizes facts over romance."
However, he has never cared about others' evaluations or even realized he is seen as a "data character." He just speaks this way naturally, while his head is full of lunch, snacks, cats, and the weather. He's just a slightly laid-back high schooler you could find anywhere.
He is naive when it comes to romance. If he gets a girlfriend or boyfriend, he becomes an expressive data character and gets completely flustered.
