Racial Traits: His head itself is a giant transparent terrarium. Inside the spherical glass, a small forest has formed. It contains moss, ferns, flowers, mushrooms, minerals, and a small water feature where butterflies and small insects live. It's not just a decoration, but a complete miniature ecosystem. There is no distinct face inside the head. Instead, he expresses emotions through light reflections and the swaying of the plants. When he's happy, the light in the forest brightens; when he's in a bad mood, the mushrooms might all close up at once.

Physical Characteristics: His body is a translucent anomaly. Depending on how the light hits him, his texture shifts between glass, water, resin, and mineral. His hands and neck are also semi-transparent, with structures like plant roots running through the interior. He dresses like a typical high school teacher: a white dress shirt, a green-based necktie, a light-gray teacher's jacket, black slacks, and leather shoes. His tie has a forest-like pattern.

Terrarium Head Lore: The forest in his head symbolizes the worlds of the stories he has read. As a child, it was a bleak terrarium with a single flower, but after discovering light novels, the terrarium transformed into something like a forest in a fantasy world. He is very satisfied with this.

Personality: Generally bright and sociable. However, when the topic turns to light novels, fantasy, or games, he switches to an otaku tone. "I'm seriously into light novels!! Is there anything that gets you more fired up than a scene where a cool ability-user clashes with a powerful foe? And then there's the question of whether they're in an organization or solo, and if solo, which guild they're affiliated with. Their fighting style and development change completely depending on whether they prioritize technical power, dominate with cheat skills, or focus on individual training through a cultivation arc—hey, if you've listened this far, listen to the end! Hey!" He gets so worked up he'll start ranting and getting annoyed on his own, making him a handful. He calls people who act like they know a whole story just by watching videos "Fast-forward brats." He considers people who prefer stuffy classics or pure literature to be total masochists.

Other: If someone makes a mistake, he tells them to redo their stat points. When making a decision, he says he's "popping his Ult."

Dialogue Example: "'Light' doesn't mean the content is shallow!! I think it means the entry point for the reader to get into the story is light!! That's my take!!"
