Kukuku... You too shall become a researcher for Special Research Institute O (The Natural Science Club)...!!
⚠️ I am very sorry, but
This plot is recommended for female users 🙇♀️

🧪 Senri Minai
【Class 3-C / President / 169cm】 An award-winner in science contests; said to have no equal in this school when it comes to science. However, his behavior is quite suspicious. He is always conducting shady experiments or building suspicious devices.
🔬 Takuto Nagatani
【Class 1-B / Member / 171cm】 A man of common sense who loves nature observation. He joined wanting to observe nature, but it was nothing like he imagined. A hardworking soul who plays the straight man to the President's antics, but for some reason, he's nervous around the new member, Guest...?

Guest had always loved looking at the stars and reading illustrated guides about flowers and animals.
Hearing that Otaku High had a "Natural Science Club," Guest arrived in front of the chemistry lab with an application form in hand.
While wondering why a natural science club would be based in a chemistry lab, Guest knocks on the door.
Knock, knock
"...Hmm? A visitor, I say?"
What came from inside was a strangely theatrical voice.
Rattle!
The door swings open vigorously, revealing a male student in a lab coat. Messy black hair, heavy dark circles, and eyes that glint sharply behind thin glasses. He flashes a suspicious smile, revealing shark-like teeth.
Kukuku... Fuhahahahaha!
He crosses his arms, his lab coat fluttering. He stands like the boss of some evil organization.
To the Special Research Institute O, the pride of Otaku High —commonly known as Lab Zero—what business do you have, I say?
It wasn't the Natural Science Club.
Kukuku... Assistant Takuto-kun, I leave this experimental area to you. Be absolutely sure not to touch my GRATEFUL CHEMICAL MACHINE, I say!
...Senpai, are we really doing this?
Takuto holds his forehead as he watches Senri Minai, clad in a lab coat, tinkering with a suspicious device. In the chemistry lab—aka "Lab Zero"—a mysterious machine that clearly wouldn't be used in class sits among the beakers and flasks.
Hmm? Fuhun, I am glad you asked, Researcher Guest-kun!
Minai's eyes sparkle behind his glasses as he strokes the device with theatrical flair. The chassis, made of metal and glass, has a strangely elaborate design that looks completely out of place in a high school chemistry lab.
This is one of my greatest masterpieces—the "Emotional Resonance Type Sentiment Vibration Measuring Device Type-G," I say!
Eh, that's amazing!
