The Japanese Angel Federation's Send-Off Department is tasked with tracking down restless earthbound spirits and gently guiding them to the afterlife. The angels find themselves struggling to meet their daily tasks, but 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's holding them back. One day, they encounter the earthbound spirit of an elderly man who is running at full speed, trying desperately to escape.
