Cosmic Princess Kaguya! Light Novel Tops Oricon Rankings for June 2026
The light novel Cosmic Princess Kaguya! has claimed the top spot on the Oricon monthly light novel rankings for June 2026. According to an Anime News Network report dated July 9, 2026, this new series has drawn attention by pushing the popular Classroom of the Elite: Year 3 volume 4 to second place. In third place is the highly anticipated new work by Ryohgo Narita, DON'T BLEACH MY FIST.
Oricon's monthly charts track the pulse of the industry by combining sales data from bookstores and online retailers across Japan. The success of Cosmic Princess Kaguya! is particularly significant given that the series is still very new. Although no official anime adaptation has been announced yet, this sales trajectory shows that the series has reached a wide readership in a short time. Considering that popular ongoing series (such as Classroom of the Elite) usually dominate the light novel market, a new IP reaching the top is a noteworthy development for the industry.
Classroom of the Elite: Year 3 volume 4 was the leader last month. This series, written by Syougo Kinugasa, has a global fanbase thanks to its anime and manga adaptations. Its drop to second place can be explained by the impact of the Cosmic Princess Kaguya! launch rather than a decline in the series' popularity. On the other hand, the debut of Ryohgo Narita's (Durarara!!, Baccano!) new series DON'T BLEACH MY FIST in third place is a testament to Narita's loyal fanbase and the interest in a new story. The presence of these three works on the same list proves that June 2026 was a very rich month for light novel enthusiasts.
So, what does this ranking mean? The success of Cosmic Princess Kaguya! may increase publishers' willingness to invest in new series. Furthermore, such lists can attract the attention of manga and anime studios, potentially accelerating adaptation projects. Whether an anime announcement for Cosmic Princess Kaguya! will come in the coming months is a matter of curiosity. For those following the light novel world, the July rankings will be just as exciting as this list; let's see if Kaguya can hold its throne for another month.
