Angels Tetsuo Tanba and Misaki Kurogane of the Dandelion Clan chase after a spirit who won't pass on to the afterlife until he apologizes to his wife.

As the other Clans rush to meet their quotas, Tetsuo and Misaki slack off until an odd robot sends them after a ring-hardened, quick-fisted spirit.

The Dandelion Clan welcomes a new, uptight member and helps an utterly charming spirit pass on by relaying a final message to her comedian husband.

When Masaki finds Misaki spending her day off in the human realm, Tetsuo shares the surprising story of how they both wound up in the Dandelion Clan.

After they encounter a spirit separated from his body, the Dandelion angels meet the scientist behind the experiment. Masaki's childhood memories surface.

Hoping to keep the Dandelion Clan in operation, Masaki introduces its newest member: Proto. But is the AI robot truly helpful or part of a shadowy plot?

The chairman's agenda rapidly reduces the number of earthbound spirits but the collection tank overloads, releasing vengeful souls into the mortal realm.
