One morning, Tokumitsu Shintaro finds a strange girl asleep on his balcony. She seems nice, but she also claims that she's an angel and that she has nowhere to go...

The peaceful cadence of Shintaro and Towa's life is interrupted by a surprise visit from one of Towa's juniors from Heaven. The tiny terror of an angel makes Shintaro reexamine their relationship.

Shintaro and Towa return from their outing for sweet treats to find Shintaro's aunt collapsed at his door. This immediately throws the apartment into a panic as Shintaro has to somehow justify Towa's presence.

Tsumugi sees the two girls by Shintaro's side and laments her own blandness. Meanwhile, Noel and Shintaro finally get the chance to do what they'd agreed to do.

Everyone has survived the final exam season thanks to being able to study in the occult research club room. They finally meet the second member of the club. However, she and Shintaro immediately get off on the wrong foot.

Will Shintaro manage to explain Towa to his friends, old and new? And how will the dynamics change in school and at work?

Shintaro gets to know Lilishka better and learns that she's pretending to be something she's not! Except it's not exactly how he envisioned it...

Shintaro, Tsumugi, and their supernatural friends decide to go to the occult research club's summer camp. As it's being hosted at Hisui's family's vacation home, they're treated to lavish service while they enjoy the beach and hot spring.

Towa and Noel come face-to-face with an emotion new to them, and they both react to it in their own unique ways.

Shintaro has racked up a few explanations he needs to make at school, while blissfully unaware of it! And at work, his girl troubles escalate as he runs into an ice queen.

Towa and Shintaro start settling into life sharing the apartment, but they have a lot to learn about living together. Still, they begin to find a rhythm before Shintaro has to return to school and insists that Towa can't follow him.

The occult club decides to end their summer camp with a bang by trying to summon devils and playing with fireworks. When they return home, Towa and Shintaro spend an entire day together out on the town.
