Premieres July 7, 2024. The new PV is here. Check out the ANN article for additional information. Synopsis from AniList:
Misora Kanata is a first-year student on the Takanosaki High School cheerleading team. She won a national championship in middle school, but can’t jump after a mistake in a competition. She befriends Suzuha, Shion, Anna, Onka, and Megumi to form the PoMPoMs. Their new team goes beyond cheerleading to reach the hearts of the people they cheer on. They might just change the world!
Not familiar with this title but could it be that character suffers injury in the plot of the series itself, hence being shown in both states?
It’s an anime-original series, so your guess is as good as mine (full disclosure, I haven’t watched the PVs). I assume that will be the case though since cheerleading has the highest rate of catastrophic injury for girls of any sport (source - pdf warning).
Summer uniforms and no wheelchair, and then winter uniforms and suddenly a wheelchair… I think it’s a solid bet that something is going to happen in that time.
