After spending 4 hours on Tomodachi Life character creation, Subaru suffered from severe eye strain for the first time. Following a friend's advice, she got facial beauty acupuncture, which relieved her fatigue and sharpened her face. However, when she told the story during a yakiniku meal with Fubuki and Okayu, Okayu remarked, "That's Illumi." Upon searching, she was shocked to discover that the acupuncture was eerily similar to Illumi Zoldyck's needle treatment from Hunter x Hunter.
