This volume contains the following tropes:
- Best Her to Bed Her: The Spirits decide to write a manga detailing their encounters with Shido to let Nia know how good he really is, but she won’t even look at it unless it can beat her manga in a sales competition. They tie, but she reads it anyway.
- Cosplay: Shido cosplays as Nia's Husbando to make her fall in love.
- Disproportionate Retribution: Nia flies into a rage, beats up Shido, and ends their date because... he wasn’t cosplaying her (male) waifu Tokiya’s character properly. She later realizes she overreacted, but then Shido upsets her again with a fake love sim game that admittedly involves putting a camera in her room.
- Mangaka: Origami, Natsumi and Yamai sisters are drawing a manga about Shido's story to compete against Nia.
- Mood Whiplash: The volume’s conflict is mostly a light-hearted manga sales competition between Shido and Nia, but just he seems to have won her over, she suddenly starts screaming in agony and Inverting. Then some light is shed on just what Nia went through under DEM’s captivity, and she gets her powers stolen and almost dies.
- Near-Death Experience: After making Nia inverse, Westcott has Artemisia extract her Qlipha Crystal and absorbs it, gaining her Demon King Beelzebub and leaving Nia on death's door. Shido just manages to save her by stabilizing what little spirit power she still has with his sealing kiss.
- Otaku: Nia is a Otaku who loves 2D boys which makes Shido's task even harder.
- Playboy Bunny: Miku, Tokha, Kotori and Yoshino dress up as Bunny Girls to advertise their manga
- Wham Line: Nia shocks everyone at the end of the volume by suggesting that all Spirits were originally human, not just Origami, Kotori and Miku.
