The official “∞劣等星” music video now accompanies the second cour of The Classroom of a Black Cat and a Witch. Highlighted by Crunchyroll News on August 3, 2026, the new opening is performed by NANAOAKARI, with tepe from OTOIRO handling the lyrics, composition and arrangements. It follows Spica, Claude and the students of Royal Diana Academy into the anime’s next broadcast segment.
- “∞劣等星” is the opening for the second cour of The Classroom of a Black Cat and a Witch.
- NANAOAKARI performs the song, with tepe from OTOIRO responsible for the lyrics, composition and arrangements.
- The anime began airing in Japan on April 12, 2026, across two consecutive cours.
- A Japanese physical edition is announced for August 26, 2026, including a Blu-ray version of the opening without credits.
Quick answer: “∞劣等星” is the second-cour opening, replacing ASCA’s “Cusp,” which opened the first cour. The anime remains legally available on Crunchyroll in the relevant territories.
Spica Virgo dreams of becoming a first-class mage, while Claude Sirius teaches magic after being trapped in the form of a black cat by a curse. Their pact drives a story that combines school comedy, fantasy and gradually developing romance. The new opening arrives after the class, setting and central relationships have already been established.

“∞劣等星” gives the second cour a faster pulse
The Japanese title “∞劣等星” plays on the ideas of an inferior star and infinity. That contrast suits Spica’s position as a struggling student trying to improve, although the title alone does not establish a new plot direction. The track has been available as a digital single since July 15.
Sony Music describes “∞劣等星” as a fast-paced, aggressive song with a rock-infused sound. tepe’s involvement as a member of OTOIRO gives the opening a clear musical identity, and the highlighted video carries that same energetic tone.
The song does more than replace ASCA’s “Cusp”: it accompanies a later stage of the same story. The first opening introduced the world and Spica’s training; the second cour begins with its group, setting and relationships already in place.
The second cour continues the same series
The Classroom of a Black Cat and a Witch began in Japan on April 12, 2026. The official website confirms a broadcast across two consecutive cours, so “∞劣等星” belongs to the second part of the series rather than a separate season 2.
That distinction matters when interpreting the new opening. Claude is still seeking to break his curse, and Spica continues her training. The change refreshes the musical atmosphere, but it does not by itself announce a production change, time skip or specific new arc.
In France, availability depends on Crunchyroll’s local catalogue and broadcast windows. The August 3 publication did not announce a specific French date.
Where to watch the anime and find the announcement
The series is available on Crunchyroll in several international regions. The official website also lists the Japanese broadcasters CBC, TBS, AT-X and BS12. Those Japanese broadcast times do not constitute a French schedule.
Crunchyroll News is the official starting point for the announcement. It is a video connected to the series’ opening, not a new trailer or a clip presented as an unreleased scene.
The song changes, while the series stays on course
The opening change gives the second broadcast segment an immediately recognizable identity without presenting it as a new season. The available information does not reveal the exact direction of the episodes or confirm a new story arc.
The natural comparison is ASCA’s “Cusp,” the opening for the first cour. “Cusp” established Spica’s starting point and training, while “∞劣等星” projects more direct energy around a class and relationships that are already established. The editorial team finds that continuity convincing, but the information available here does not support conclusions about any change in production itself.
For viewers, the effect is straightforward: a new musical appointment accompanies the second-cour episodes without requiring anyone to restart the story. Music fans can revisit the digital single released on July 15 or wait for the Japanese physical edition announced for August 26. No specific French availability or international bonus has been confirmed.
The Japanese physical edition arrives on August 26
A Japanese physical edition of “∞劣等星” is announced for August 26, 2026. One version includes a Blu-ray featuring the opening without credits. This release is intended for music and collecting purposes, not early access to the anime.
For the series itself, the relevant option remains Crunchyroll’s legal stream, depending on the country. The official website remains the place to find the synopsis, characters and LIDENFILMS credits. Upcoming announcements can also be followed through the news section.
The opening sets a tone, not a plot summary
“∞劣等星” introduces a more aggressive musical tone for the continuation, but the publicly available information does not show how that mood will translate into the episodes. The comparison with “Cusp” indicates a musical evolution; it does not establish a new arc or predict an ending for the characters.
