Risa Hoshizaki

As the younger sister of Hoshizaki Rika, she is active in the gaming streaming scene under the name 'Risapon.' Her temperament stands in stark contrast to her impulsive sister—she approaches situations with calm composure and a maturity that exceeds her years. Throughout the story, she serves as the behind-the-scenes strategist for her sister, repeatedly devising plans to help her pursue Naoya, while also delivering pointed commentary on her sister's behavior. She stands out as one of the few genuinely sensible characters in the series.
