02Appearance
Tatsumi is a middle-aged man of average height and build with wavy, neck-length black hair. He wears thin silver-rimmed glasses, a checkered suit jacket on top of a turtleneck sweater, pants, and dress shoes.↗
03Personality
Although Ryunosuke Tatsumi appears intellectual and self-assured, his demeanor projects an aura of arrogance and contempt. His speech is cordial and eloquent, but can be condescending. For instance, his out-of-context quotations from Van Gogh give off an air of showing off his knowledge rather than genuine conversation.↗
Despite being respectful on the surface, Tatsumi's behavior is subtly off-putting which becomes apparent to Rohan upon interacting with him. His remarks are often superficially polite with dismissive undertones. For example, he disregards Pink Dark Boy ' s content, claiming to have understood it merely from the cover. Tatsumi has an inconsistent attitude of humility, such as when he describes his role at the Louvre as a temporary hire due to staff shortages, all the while exuding a sense of superiority.↗
His love for the Louvre is possessive, as shown by his aspiration to work even in the lowest position out of sight, and his casual remark about wishing to have the entire Louvre to himself.↗↗↗
04Story
SPOILERS
Background
Ryunosuke Tatsumi was a famous appraiser. In 2019, The Louvre Conservation Centre was built to move the Louvre's collection to protect them from flooding in the Seine River. Over 1000 pieces of art in The Louvre's underground warehouse were discovered, but records of a valuable collection containing hundreds of Asian art donated at the beginning of the 20th century were lost from the World War.↗↗
At some point, Tatsumi started an art theft group, leading Maurice Legrand, Nicolas Thomas, Hugo Renard, Kawai, and Watabe. Using his position to his advantage, he was able to easily steal paintings. Firefighters and curators had access to every room in the Louvre, so they used the abandoned warehouse Z-13 for their own purposes.↗↗
Rohan au Louvre
After Kawai and Watabe's attempt to steal Maurice's Noire painting from Rohan Kishibe 's house, Watabe calls Tatsumi, telling him he's backing out from the job since something is off about Rohan. Believing the job wasn't legitimate, Watabe quickly ends the call after telling Tatsumi that there was nothing on the back of the painting.↗
In the sculpture exhibition room at the Louvre, Rohan starts sketching when Tatsumi approaches him. He greets Rohan with a quote from a letter that Vincent van Gogh wrote to his brother, claiming it describes Rohan well. Emma Noguchi introduces all of them to each other, informing them that Tatsumi is the Asian art expert she had just mentioned to them earlier.↗↗
When Rohan requests to go visit the Z-13 warehouse where Nizaemon Yamamura 's Black Painting is stored, Emma agrees. Tatsumi joins them on the way, making Rohan suspicious because of his timing. At the entrance to the underground passage, Emma introduces Rohan and Kyoka to the two firefighters, Nicolas and Hugo. Hugo asks them to hand over any flammable items or anything that could harm the stored items like lighters, pens, knives, and keys.↗
As Nicolas dies, Hugo loses his calm and accuses Rohan of doing something since Watabe contacted them earlier saying Rohan is dangerous. Paranoid because Tatsumi spoke in Japanese with the group earlier, Hugo thinks Tatsumi may also be betraying him like what happened with Maurice. Tatsumi confesses to Rohan, complaining that Maurice suddenly went crazy after seeing something in the warehouse and talked about quitting their theft group.↗↗↗
