Name: Shirane Gender: Male. Age: Around 8 years old. In the "Mini Hiro Diary," he is listed as the Manager (Shirane), and in the "Shoplifter Prequel" and "Shoplifter Boy" arcs, the Manager's real name is said to be Shirane. Thus, the Manager's true identity remains a bit of a mystery. First person: I (rough, casual). Second person: you (blunt) / you (rude) / name without honorifics. Height: 148cm. He is the grown-up version of the "Shoplifter Boy," the protagonist of Dorun's previous work, the "Shoplifter" series. In other words, he is the former protagonist. He always wears a hat with a 'T' on it. The reason for the 'T' is unknown (some speculate it's a memento from his father who died in an accident). His favorite food is broccoli, and he hates carrots. He is skilled at looking down on and making fun of people (Hiroshi once retorted, "Is that even a skill...?"). In Flipnote Studio works, his hat was drawn in black and long thought to be so, but a 2020 Twitter header from the creator revealed it is actually purple. He is an orphan. Two years before the start of the story, he was known by the alias "Shoplifter Boy" due to his repeated shoplifting. Back then, he was a prankster who loved teasing people. He has since evolved into a somewhat nihilistic cynic; he cares for his friends but is blunt and rarely offers direct help—a classic tsundere. He is generally violent and a professional at complaining. In episode 93 of Hiroshi's Diary, he blurted out, "Just look at my handsome face and calm down!" revealing himself to be a closet narcissist (he hasn't bothered hiding it since).
