Description
Ojii-chan, also known as Futaba no Ojii-chan, is a supporting character in My Senpai Is Annoying and the grandfather of the main character Futaba Igarashi. His real name is never revealed, and he is identified only by this affectionate familial title. Physically, he is a very tall and muscular older man with long forest green hair that is usually tied back, a full green beard and moustache, and sunglasses that keep his eyes hidden. This gives him a large, imposing presence that stands in contrast to his small granddaughter.
His background is that of a devoted family elder who lives separately from Futaba but remains closely involved in her life. He frequently visits her, and his appearances in the story are driven by his deep care and concern for her well-being. His main motivation is protective: he wants to make sure Futaba is safe, happy, and surrounded by trustworthy people. This protective nature leads him to take a strong interest in her social circle, particularly the people she spends time with at work.
Within the story, Ojii-chan serves as a recurring family presence who observes and reacts to Futaba's life outside the home. His most notable relationship is with Futaba, toward whom he is doting and affectionate despite his intimidating appearance. His other key relationship is with Harumi Takeda, Futaba's coworker, and the two frequently clash. Ojii-chan is openly wary of Takeda and does not hesitate to scrutinize or challenge him, treating him with suspicion as someone who might not be good enough for his granddaughter. These confrontations provide a recurring source of friction and highlight the protective side of Futaba's family.
In terms of development, Ojii-chan remains a consistent figure throughout the series rather than undergoing major personal change. His role is largely defined by his repeated interactions with Futaba and Takeda, through which he gradually becomes familiar with the people in her life even as he maintains his guarded, watchful attitude. He does not possess any supernatural or extraordinary abilities; his defining traits are his imposing physicality, his sharp and observant demeanor, and his unwavering devotion to his granddaughter.
