Studio Apartment, Good Lighting, Angel Included

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...

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.

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.

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

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.

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.

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...

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.
