Long ago, the gate to the world of darkness was sealed. Now evil warriors, known as Remnants, are trying to reopen the gate and let demons take over the world. However, at Tobira High School, there exist guardians of the gate who must risk their lives to prevent the gate from being opened.

以天使丹波铁男和黑铁美咲为中心的故事。

他们隶属于天使联盟接送部·蒲公英组，每日繁忙工作。他们的任务是将那些因留恋尘世而无法离开现世的灵魂们送回彼岸。由于地缚灵基本上都会四处逃窜，所以他们大部分时间都在进行追踪。

一个充满人情味与幽默，令人笑中带泪的故事。
