Summary
The day of the Geika Fashion Show has begun and all of the contestants including, Ikuto prepare for it. Ikuto's sisters and mother are shown in the auditorium of where the show will be held.

Eventually, the judges are introduced, two of which are Seira and Shoko and in the audience is Mai Ayano. Also watching the show from afar is Yu and is soon approached by Shizuku. Much to Yu's chagrin, Shizuku offers to watch the show together. Elsewhere, Ikuto's family watches the show and are all impressed by the designs that are lined up. Meanwhile, Ikuto is stuck in the bathroom with stomach cramps. When he gets out he witnesses Kaoru prepare for her part of the show and proclaims she'll crush Ikuto in the show. In Kaoru's inner monologue, she reveals that she's envious of Ikuto's talent after believing he ruined Hajime's designer show in the past. Furthermore, she states that she hates losing and her designs are well received by the crowd and judges.

On the audience floor, Shizuku and Yu head to the front of the runway so Shizuku can record it as Ikuto's turn is next. His first piece is noted to be inspired by Britain while the second and third appear Scandinavian inspired. The fourth and fifth are Italian themed with the fourth having some elements from Siciliy on it. Sequentially the sixth piece is Japan-themed and the seventh is a bold and impressive American themed one. The eighth and ninth themes are Germany and France and in the audience, Mai is impressed by the designs. For Ikuto's final design, his theme belongs to no country and is just a plain minimalistic design. This design captivates the judges and earns Ikuto a round of applause.

Up next is Kokoro and Chiyuki.
