Set within the Send-Off Department of the Japanese Angel Federation, Dandelion follows angels Tetsuo Tanba and Misaki Kurogane as they track down earthbound spirits—souls unable to move on and find peace—and gently guide them to pass on. The angels find themselves struggling to meet their daily tasks. However, Tetsuo Tanba and his leader, Misaki Kurogane, who make up the 21st Division's Dandelion Clan, choose to take things at their own pace: instead of rushing through cases, they take time with each spirit, listening to their regrets and helping them resolve what is holding them back. One day, they encounter the earthbound spirit of an elderly man who is running at full speed, trying desperately to escape.

The story centers on the contrasting partnership between its two leads. Tetsuo Tanba presents a cold exterior with sharp words but possesses a deeply caring heart. Misaki Kurogane, the clan leader, has an appearance that seems cute yet wields extraordinary strength, with rumors suggesting she once helped pacify the legendary spirit of Miyamoto Musashi. Their empathetic approach defines the Dandelion Clan, setting them apart from other divisions that handle cases more mechanically. The narrative explores the lingering regrets of the dead, with each spirit encountered presenting a unique emotional knot that must be untied before they can find rest.

Based on the debut manga by Hideaki Sorachi, the creator of Gintama, Dandelion originally appeared as a one-shot in Weekly Shonen Jump in 2002. The anime adaptation is produced by studio NAZ and directed by Daisuke Mataga, with series composition by Yosuke Suzuki, character designs by Ai Asari, and music composed by Yuki Hayashi. The main cast features Chikahiro Kobayashi as Tetsuo Tanba and Megumi Han as Misaki Kurogane. The series is scheduled to premiere globally on Netflix on April 16, 2026, presented as a web anime consisting of seven episodes that expand upon the original short story.
