It has been confirmed that the Kaguya-sama: Love Is War manga is ending in its next chapter, which is scheduled to be published in Weekly Young Jump on November 2, 2022.
The story of the manga is described as:
All’s fair when love is war.
Two geniuses. Two brains. Two hearts. One battle. Who will confess their love first?
Kaguya Shinomiya and Miyuki Shirogane are two geniuses who stand atop their prestigious academy’s student council, making them the elite among elite. But it’s lonely at the top and each has fallen for the other. There’s just one huge problem standing in the way of lovey-dovey bliss—they’re both too prideful to be the first to confess their romantic feelings and thus become the “loser” in the competition of love. And so begins their daily schemes to force the other to confess first.
Akasaka began the Kaguya-sama: Love is War manga in Shueisha’s Miracle Jump magazine in May 2015 but it moved to Young Jump in March 2016. VIZ Media is publishing the manga in English.
