Nezu Daikichi is the eldest son of the Nezu family. He's known for destroying things (mostly unintentionally).
When he was still in school, Daikichi's appearance was virtually indistinguishable from the rest of his family. His eyes were often hidden by his long bangs.
By adulthood, Daikichi's hair became much shorter. His eyes are now visible at all times.
Daikichi is infamous for being destructively clumsy. He's always accidentally hitting his head on doorways and tripping over, often breaking something in the process. A major part of his family's impoverished circumstances are due to reimbursement sought out by people whose property Daikichi ruined.
