Sōta Shiki, the dependable older brother of Souma, navigates his dual roles as a senior employee at Takayuki Mima’s company and a guiding figure for his juniors. His evenings often extend to after-work drinks with colleagues, offering a reprieve from workplace pressures. The bond between the Shiki brothers thrives on mutual reliance: Sōta cherishes Souma’s quiet emotional grounding while gently cautioning against his brother’s single-minded passions, revealing a nuanced protectiveness.

At the office, he balances corporate duties with mentorship, though his relentless work ethic occasionally stirs private doubts about whether he can fully uphold his supportive role. This self-awareness lingers during interactions, a quiet counterpoint to his outward zeal. Sōta’s demeanor blends a buoyant, lively personality with pragmatic problem-solving, urging others to tackle obstacles with self-assurance.

Within social circles, he operates as an unofficial anchor, seamlessly navigating roles as a sibling, colleague, and trusted advisor. His presence prioritizes camaraderie—sparking collective enthusiasm during collaborations or lightening tensions with his easy humor. Across both family and career, Sōta remains a steadying force, quietly harmonizing responsibility with relational warmth.
