How Misaki Kuno, Mariya Ise, and Shunichi Toki Developed Their Roles in "SHIROHIYO - Reincarnated as a Neglected Noble"? "SHIROHIYO Cast and Episode 1 Broadcast Celebration Special"

Moving on to Regulus, Ise commented that it was her first time playing a character as a “three-year-old” throughout the entire show: "I was worried if I could pull it off, but I poured my energy into acting as a real three-year-old." This drew high praise from Kuno and Toki: "Your understanding of a three-year-old is amazing!" and "Everyone was soothed by Mariya’s portrayal of Regulus."

Toki added, "Every time Ise-san spoke, Aki Toyosaki, who plays Princess Hyakka, was literally looking up to the heavens at the back of the booth (laughs)." He continued, "Just with the word ‘big brother’ (‘nii-nii’), Regulus’s emotions are conveyed perfectly. I’d love to see a compilation after the series ends, like a ‘nii-nii collection!’" bringing laughter to the set.

Toki, who plays Romanov—an elf, Ageha’s tutor, and one of the few in the empire to hold the title of hero—confessed that he was troubled by the dynamic. In this world, elves are written as being uninterested in humans, and as Romanov is not family but a tutor, Toki reflected on maintaining the right distance with Ageha. He explained sincerely, "As a tutor, I look forward to Ageha’s growth, and I imagine Romanov also has a biological curiosity about him. I tried to leave that sense of intangible distance in my performance."

Ise responded, "Toki-kun’s gentle demeanor and warm vibe fit Romanov-sensei perfectly. Just listening to your lines was as comforting as getting into a hot spring," giving her seal of approval to Romanov’s warmth.

An Outpouring of Adoration for the Adorable "SHIROHIYO Brothers"! Healing Laughter-Filled Variety Segments, Too!

Later in the program, they introduced other captivating characters, including other elves, gods, and the Kikuno family’s maids. When the segment "Compilation of Cute SHIROHIYO Brothers Scenes" was shown, the cast couldn't help but exclaim things like "Aren’t they just too cute!?" and "They’re dazzling!" resulting in an eruption of excitement as they fondly looked back on the story.

Furthermore, the program featured variety segments such as "Even a Chick Brother Can Understand! Storybook Relay Explaining the Appeal," in which the cast took turns presenting the story of SHIROHIYO in a picture book format, and "Let’s Play with Piyo-chan! ABEMA Special Edition!" commemorating the show's collaboration by playing various games with Piyo-chan. In the "Storybook Relay," a hilarious “master artist” emerged, while in "Let’s Play with Piyo-chan," there was even a moment when Piyo-chan perfectly synchronized with Ise as the voice of the chick (Regulus)! The studio was in high spirits throughout these heartwarming and laughter-filled segments.
