Designating February 13th as "Onii-sama Day" is undoubtedly the highest tribute to the profound respect and affection the heroine, Miyuki Shiba, holds for her brother in the series. In the visual released on this memorable day, Tatsuya Shiba reveals a completely different side:

• New Look: Departing from his usual school uniform, Tatsuya now wears a sharp black suit, his expression stern, radiating an undeniable aura of power.
• Promotional Tagline: The visual is accompanied by the tagline "Prepare for the strongest impact (最強の衝撃に備えよ)", hinting that audiences will witness unprecedented, shocking plot developments and magical battles in the "Yotsuba Succession Arc".
