Cool Exterior Warm Interior
As the older brother to the twin duo Risei and Airi, his entire world revolves around the two girls he cherishes above all else. His notorious sister-complex manifests in an encyclopedic knowledge of their preferences and an unwavering commitment to handling all household duties himself. While his behavior can occasionally come across as over-the-top or even improper, beneath that exterior lies a genuinely warm-hearted protector who would go to any lengths for his sisters.
