Chouji Nakazaike  

, 中在家 長次

The student you're referring to is known for being extremely reserved with a scarred face. When he speaks, his voice comes out as low mumbles. It's common for someone who knows him well to serve as an interpreter when communicating with him. Kirimaru, who is part of the Library Committee along with him, often helps in this capacity. His default facial expression is a blank one that gives off a sullen vibe. However, on rare occasions, such as when he's angry or worked up, his expression changes to a creepy smile accompanied by an eerie laugh. Despite this intimidating appearance, the student is actually very kind and thoughtful. Kameko, Shinbei's little sister, has developed feelings for him.
