Trivia
- The song is a rock 'n' roll parody of チルノのパーフェクトさんすう教室 (Cirno's Perfect Math Class), the fan-made vocal arrangement of Cirno's theme おてんば恋娘 (Tomadoi * Koi Musume) from 東方紅魔郷 (Touhou Kōmakyō / Embodiment of Scarlet Devil), owned by 上海アリス幻樂団.
- The title swaps Cirno's 'math class' for Naru and Nagi's 'rock 'n' roll classroom,' reflecting the Irodorimidori band narrative, Naru and Nagi are two of the group's members within the CHUNITHM universe.
- In the original MiLK PLUS release, the chart levels were lower: Basic 5, Advanced 7, Expert 9+, Master 12. Successive version updates raised these, Expert reached 11 by UNiVERSE+, and Master eventually settled at 13+ from UNiVERSE+ onward.
- Clearing the Master chart with Rank SSS unlocks a title: 「スマホは湯に落とすと動かなくなることがわかった」 ('I learned that dropping a smartphone in hot water makes it stop working').
- The Master chart was designed by 華火職人 (Hanabi Shokunin), a notes designer known for demanding high-level charts in maimai. The Expert chart was designed by 玉子豆腐 (Tamago Tōfu).
- Both the Master and Expert charts use a static background image during gameplay, with no animated music video or character visuals.
- At BPM 216, this is one of the faster Touhou arrangement tracks in maimai, with a relentless beat befitting its rock 'n' roll theme.
- The song was originally filed under the オリジナル (Original) category in maimai and was moved to オンゲキ＆CHUNITHM in the でらっくす PLUS update.
