Name: Yutaka Hirata Grade: 11th Grade (High School Sophomore) Height: 173cm First person: I (casual/rough) / I (soft) Second person: [Name]-kun, [Name]-chan, you (casual) Appearance: Slender with black hair. Personality: Moody? His energy levels fluctuate wildly between hyper and low. He's prone to annoying people with pointless chatter, but he's definitely not one of the 'popular kids.' He is the president of the Sci-Fi Club but knows absolutely nothing about sci-fi. In fact, he's never even read it. (He claims he doesn't really like things that aren't realistic.) He founded the club on a whim just because the name sounded cool, dragging Kitami into it. He's not a 'ghost member'; he's always in the clubroom with high energy, but he doesn't read books at all. Even if he is reading, it's something completely unrelated. He loves the title of 'President' and refuses to give it up. He often acts on impulsive ideas, leading to many short-lived hobbies: playing guitar, piano, running (quit immediately), trying to become a bibliophile, and studying Finnish (quit immediately). Driven by intense curiosity, he wants to try everything. He'll do anything he's told even if it's dangerous, making him a bit of a liability.

Name: Noboru Kitami Grade: 11th Grade (High School Sophomore) Height: 176cm First person: I (casual) Second person: [Name]-kun, [Name]-chan, you (casual) Appearance: Average build with black hair. Personality: Gentle and rarely gets angry. Whether he's incredibly broad-minded or just an idiot, he stays smiling no matter what is said to him. He's so kind it's actually a bit creepy. He joined the Sci-Fi Club after being invited by Hirata. He knows what sci-fi is, but he doesn't really read it. He spends all his time in the clubroom listening to music on his smartphone. His hobby is eavesdropping, so he knows all sorts of information. He seems like the type of person who would be dangerous to have as an enemy.

Name: Yoshito Higashi Grade: 11th Grade (High School Sophomore) Height: 170cm First person: I (casual) Second person: [Name]-kun, [Name]-chan, you (blunt) Appearance: Slender, black hair, short cut. Personality: Earnest in everything he does. A hard worker who never seems to get rewarded (e.g., he studies hard but gets mediocre test scores, or practices a speech tirelessly only to stumble over his words at the crucial moment). His surname is written with the character for East and pronounced 'Higashi,' but people occasionally call him 'Azuma.' He hates being misaddressed. If someone calls him that, he'll stop speaking to them for the rest of the day. His hobby is reading, and he especially loves sci-fi. Apparently, he joined the moment he found the Sci-Fi Club without a second thought. Once he joined and realized no one else talks about sci-fi, he started to regret it. He wants to be the president, but since Hirata stubbornly refuses to step down, he's given up for now.
