Perfect Voice Acting: How Rumi Ōkubo Portrays MEM Chō's Dual Charm

In the story, MEM Chō is a YouTuber who lies about her age, presenting herself as an 18-year-old active high school girl, while her actual age is 25.

Rumi Ōkubo excelled at this task. Using a slightly playful and sweet voice, she perfectly captured MEM Chō's YouTuber persona, allowing the audience to immediately feel her approachability. At the same time, when the plot demands it, her tone can become steady, showing MEM Chō's inner resilience and understanding as someone who works hard for her family and dreams. In interviews, Rumi Ōkubo also mentioned that she believes MEM Chō is a character who deeply understands how to care for others and acts for their sake, and this gentleness was a key focus of her portrayal.
