Movie
Description
Kiyosuke Azuma is a character from the 19th animated film in the Detective Conan series, portrayed as a figure whose actions in the past are central to the movie's mystery. He is voiced by Toru Okawa in the original Japanese version. Kiyosuke appears only in flashbacks, with his story set against the backdrop of World War II in Ashiya, Japan. During that time, he was a carpenter hired to work in the residence of a wealthy businessman named Koyata Yamamoto, which is where he formed a connection to the Van Gogh painting titled Still Life: Vase with Five Sunflowers.

Kiyosuke Azuma was a man with a quiet but profound sense of duty. Despite being married and having a son, he was the object of secret affection from Umeno, a young housekeeper at the Yamamoto residence. He was also a great friend to Konosuke Jii, a fellow servant who was also in love with Umeno. His personality is defined by his courageous and selfless final act. In 1945, when Ashiya was bombed, the Yamamoto residence caught fire. While the building was burning around him, Kiyosuke risked his life to save the valuable sunflower painting that was attached to the wall for protection. Recognizing its importance, he retrieved the artwork from the flames and, knowing he would not survive, entrusted it to Umeno with the dying wish that it would one day be displayed in a museum in Japan for the whole world to see. His motivation was not personal gain or recognition, but a belief in preserving a masterpiece for his country’s future.

His role in the story is that of a catalyst, as his heroic sacrifice directly shapes the events of the present. Kiyosuke is the grandfather of twin brothers, Koichi and Koji Azuma. A year before the movie's main events, the twins followed the trail of his story and successfully located the long-hidden Sunflowers of Ashiya in Arles, France. His legacy is a point of conflict, as one of his grandsons becomes entangled in the criminal plot surrounding the painting. Key relationships from Kiyosuke’s past include his unspoken connection with Umeno, who cherished his memory for decades, and his friendship with Konosuke Jii. Jii witnessed Kiyosuke’s final moments, rescuing both Umeno and the painting, and spent his life as a keeper of this secret history, ensuring that Azuma’s wish was ultimately fulfilled. Kiyosuke himself undergoes no development as he is a figure from the past, but his enduring legacy provides a resolution for the older characters and reveals the true, noble origin of the painting now at the center of the exhibition. His notable ability was his quiet resolve, demonstrating exceptional bravery and physical effort to save a priceless work of art from an inferno, sacrificing his own life for what he believed was a greater cause.
