Description
Daikichi Terayama is the deceased great-grandfather of the protagonist, Suekichi Terayama. He is a central figure in the story even after his death, as the conditions of his will form the primary conflict that drives the narrative forward. Daikichi left behind a substantial inheritance, reportedly an off-the-books stamp collection valued at over 400 million yen, but with specific stipulations for his heir. Suekichi can only claim this fortune if he successfully finishes university, gets married, and finds a job.

Despite being deceased, Daikichi Terayama is a very active presence throughout the series, as he does not rest quietly. Rather, he appears as a ghost who finds great amusement in haunting his great-grandson, often materializing at the most inopportune or embarrassing moments to taunt him rather than to scare him. He has a mischievous and playful personality, taking pleasure in meddling with the living. His antics include peeping on characters and even possessing people, using his spectral abilities to cause further chaos and complications in Suekichi’s already difficult life. Daikichi’s motivations seem to stem from a desire to control his legacy from beyond the grave and to ensure his instructions are followed, while simultaneously having fun at his descendant's expense.

His role in the story is that of a catalyst whose posthumous demands and ghostly interference force the protagonist into a series of challenging situations. He communicates his bequest in a lavish video recording, in which he reenacts a past encounter with a con-woman who offered him companionship and "sexual healing," revealing a flamboyant and unashamed side to his character. His key relationship is with his great-grandson, Suekichi, which is defined by a dynamic of manipulation, frustration, and dark comedy. Daikichi’s character does not undergo development in a traditional sense, as he is already a ghost, but his persistent and intrusive actions are a constant source of disruption throughout the narrative. His notable abilities include the power to return as an apparition at will, the capacity to haunt and taunt the living, and the ability to spy on people and possess their bodies.
