On September 28th, actor Sato Ryuta and actress Kato Ai attended a presentation event for TV Asahi�s special drama, "Hikaru Hekiga".

The drama is based on Yoshimura Akira's novel of the same title. It portrays the story of Japanese researchers who developed the world's first capsule endoscopy.

Sato, who will be playing a married couple with Kato for the first time commented on their 10 year friendship saying, "Back then Ai-chan would come on set in a uniform. When the role of the married couple was confirmed, I was happy, but also embarrassed." Kato also stated, "I was embarrassed, but we harmonized. I feel at peace when I'm together with Ryuta-kun."

Sato will play the role of the devoted researcher 'Sone Kikuo'. He shared that he learned about this great achievement through the drama, and expressed, "I challenged myself for the first time to the difficult period after the war. Being Japanese, I am proud of the achievement, and I was also given courage."�Meanwhile, Kato, who plays the role of Kikuo's wife 'Kyoko' commented in wonder, "To come up with that idea, and create it during that time is amazing�"

Since the drama reflects the passion of researchers, Kato was asked about something she worked hard for. She replied, "The first thing that comes to mind is my graduation thesis during college. I had to take up difficult themes, and spent a lot of time in the library." Kato then surprised her co-stars by sharing that her theme had to deal with "sanctions on terrorism."

Hagiwara Masato and Nakamura Shunsuke also attended the event.

�Hikaru Hekiga� will air on October 1st from 9:00 pm.
