UPDATE: The tweet was indeed a season 3 tease! The 7 hearts referred to 7 hours, and a new visual and trailer were already released for season 3 of Kaguya-sama, together with an April 2022 release date.
Almost a year since Kaguya-sama: Love is War Season 3 news first got announced, the official Twitter account for the franchise posted a mysterious tweet featuring 7 hearts. It came at exactly midnight between Wednesday, October 20 and Thursday, October 21 (JST), and we can only guess what it means at the moment. The post features visuals from the previous 2 anime seasons, and you can check it out below:
Many fans assume it’s a countdown, with 7 being the number of days until we get some details about the sequel. A new visual/trailer or just the release date, anything would be welcome for the fans of the romcom. The season 3 announcement came on October 25, 2020, along with a 3-episode OVA for Kaguya-sama. The OVA episodes came out on May 19 this year.
So far, the series received 2 anime seasons by A-1 Pictures, which were incredibly well received. Season 2 was even voted as the Anime of the Year for 2020 by our fans, with votes from 47,323 people! Besides the OVA episodes, it also has 2 live-action films. Funimation streams both seasons, while VIZ licensed the manga in English. They describe the story:
As leaders of their prestigious academy’s student council, Kaguya and Miyuki are the elite of the elite! But it’s lonely at the top… Luckily for them, they’ve fallen in love! There’s just one problem—they both have too much pride to admit it. And so begins the daily scheming to get the object of their affection to confess their romantic feelings first…
In addition, the manga is entering its final arc today after a 1-week break.
