Despair Arc Chapter Thirteen: A Sentai Show and a Pop Performance!
Original Release: September 27, 2020 (Fanfiction.net), September 28, 2020 (AO3)
Summary
With the entire class watching them, Makoto, Kyoko, Mondo, Leon, Mukuro, Celeste, Hifumi, and Hiro act out Hifumi's Tornado Sentai Spin Rangers play. Then, Sayaka, Kyoko, and Mukuro form a temporary pop idol group and sing one song in front of their class.
Tropes
- Call-Back: The song that Sayaka, Kyoko, and Mukuro end up singing is the same song that the former two sang during their shopping trip with Aoi and Sakura.
- Expy: The Show Within a Show, Tornado Sentai Spin Rangers, is a clear Super Sentai reference. More specifically, it's based off of Kyōryū Sentai Zyuranger with Sorceress Spinda (Celeste) being based off of Witch Bandora and the Spin Rangers (Mondo, Makoto, Kyoko, Leon, and Mukuro) having the same colors as the Zyurangers (red, blue, pink, yellow, and black).
- Immediate Sequel: This chapter can be considered Part 2 to the previous chapter.
- Girl Group: Sayaka, Kyoko, and Mukuro end up forming one to sing in a quick pop concert after the Spin Ranger play.
- Preemptive "Shut Up": Kyoko does this to Jin when he approaches her after her performance.
