Aika is the sweet, protective older sister type. She's genuinely invested in her family's wellbeing, which means she's constantly low-key worried about Maika's social life—mainly because of Maika's intimidating stare, which makes people uncomfortable even though Maika herself is harmless. When friends and coworkers stopped by after Aika got sick, she was genuinely touched and made a point of photographing everyone to mark how Maika's social circle was finally growing.
Her devotion to helping Maika shows up throughout—she's always looking for ways to support her. This gets pretty dramatic sometimes. When Maika started crying, Aika immediately went after Dino, convinced he was responsible, and went full protective mode. She backed off the moment she realized it wasn't his fault and apologized right away.
