Description
Itsuki Hashima is the protagonist of this narrative, a twenty-year-old professional light novelist who specializes in and is obsessively devoted to the little sister genre. He has brown hair and brown eyes, and his physical appearance is that of a typical young man. He lives alone in an apartment where he writes his stories and hosts his circle of friends, and his younger step-sibling, Chihiro, regularly visits to cook and clean for him.
On the surface, Itsuki is an unapologetic pervert with a singular fixation on creating the ultimate little sister character in fiction, which often manifests in the stories he pitches to his long-suffering editor. He can be arrogant about his abilities as a writer and is known for his sarcastic and snarky demeanor, frequently directing his wit at his friends Nayuta and Haruto. Despite this, he is described as a fundamentally good and honest person who shows genuine sensitivity and care for those close to him. He is a brilliant but often lazy talent, spending much of his time goofing off and playing board games with his friends, which forces his editor to take extreme measures, such as locking him in a cell, to get him to meet his deadlines.
Beneath his confident exterior lies a complicated and sensitive individual driven by deep-seated insecurities. As a child, Itsuki was a loner with few friends, a situation that was exacerbated by the death of his mother during his middle school years. A key event in his past was being rejected by his first love, Ayane Mitohara, which was a devastating emotional blow that he has never fully recovered from; he believes this trauma is what ultimately shaped his obsession with the fictional, idealized little sister archetype. He also has a very strained relationship with his father, Keisuke, due to both his father's remarriage and the disapproval of Itsuki's career choice and interests, leading them to stop speaking after Itsuki moved out. This history fuels his overwhelming desire to be special and to feel like the protagonist of his own life.
In the story, Itsuki acts as the central figure around which the other main characters gather. He is the anchor for a group of fellow creators, including the genius but perverted novelist Nayuta Kani, his more commercially successful friend Haruto Fuwa, and his sensible college friend Miyako Shirakawa. His relationship with Nayuta is particularly central, as she is openly in love with him. However, Itsuki is revealed to be an insecure love interest who secretly returns her feelings but feels unworthy of her. Because he views her as a literary genius who overshadows his own work, he believes he must achieve a level of success that makes him her equal before he can confess his love. He is largely oblivious to the feelings of others, such as Miyako's romantic interest in him, until they are bluntly stated.
A major turning point in Itsuki's development occurs when he learns the truth about his step-sibling Chihiro, who was raised as his younger brother but is revealed to be his actual little sister. Discovering he has a real sister triggers a profound psychological crisis. He finds himself unable to pour his former love for the little sister genre into his published works, as doing so now feels gross and unsettling. This leads to a long period of writer's block lasting half a year, during which he produces only bland, uninspired novels. This creative and emotional low point ultimately causes a significant rupture in his relationship with Nayuta. Despite this breakdown, he consistently demonstrates his care for Chihiro, offering financial support with no strings attached and eventually reconciling with his father in an effort to be there for her.
Itsuki's notable ability is his talent as a writer. When he applies himself, he is capable of producing genuinely good stories that sell well, and his work serves as an inspiration to others, most notably Nayuta, who credits his novels with saving her from a life of depression and isolation. His primary struggle is not a lack of ability, but his own ego, insecurities, and procrastination, which he must constantly battle to succeed in his career and personal relationships.
