A high school student who gets roped into being Takane's unofficial "closet"—basically, he has to swap out her underwear whenever she strips down. It's an awkward gig that comes with a weird perk: he's the only person who's ever seen her naked, which means he's the only one who can actually follow her whenever she does a time loop.
At first, he was just trying to cover his own ass. Getting caught as the guy who apparently groped Takane wasn't exactly appealing. But he actually starts taking the job seriously pretty quick, motivated more by keeping her from getting humiliated than anything else. Looking back on it later, he admits he had no idea she was already into him during those early days—he was too busy panicking about the whole situation to notice.
