A poorer outcome for Jaku-Chara Tomozaki-kun’s 10th volume when compared to Volume 9. 6-day sales are down by 21.71% debut-to-debut to 8,831 copies. Volume 9 was at 11,280 copies back on January 19, 2021. Unfortunately, the news of a new Anime project for the title did not serve as a boost for the 10th volume. In case you missed out on the announcement, it was made on January 14, and that a new Anime project was said to be in production (Source: ANN). You can also check out the announcement video down below. Between January 8 and March 26, 2021, the series was adapted into a 12-episode Anime series by Project No. 9. It also has a Manga adaptation which did not last very long, lasting only six volumes.
It is thanks to the wonderful people over at Oricon that we get to see these charts on a weekly basis, so be sure to head over to their site here and show them lots of love! In addition, all the data you find below is accessible via Oricon right here (Light Novel), here (Bunko) and here (Bungei-sho). The respective Google chart is also found at the bottom of the post if you are more comfortable with that.
The rest on the chart is filled with new releases with Shousetsu Idakaretai Otoko Ichii ni Odosarete imasu. Shinryoku no Kishukusha by author Yoshimi Narita placing 3rd on the list at 7,501 copies sold in its first 4 days. You may be interested with Number 5’s Date A Live Another Route, which was authored by a number of popular individuals, including its original author. For instance, Fujino Oumori is known for Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka while Yuuichirou Higashide worked on Fate/Apocrypha. Date A Live Another Route sees its 4-day sales at a rather decent 5,875 copies sold.
Shinjiteita Nakama-tachi ni Dungeon Okuchi de Korosarekaketa ga Gift “Mugen Gacha” de Level 9999 no Nakama-tachi wo Te ni Irete Moto Party Member to Sekai ni Fukushuu & “Zamaa!” Shimasu!

Note, for Number 9’s Heian Ayatoki Soshi: Sono Nyonin, Nioyaka naru Koto Hakubai no Gotoshi Volume 8, I have considered to take it as Honto listed it as a Light Novel on its chart, and CDJapan has a small label denoting that it is a Light Novel too. The same can be said for Number 12’s Shiro Butahi Sairaiden Koukyuu mo Nidome nara Volume 2. Heian Ayatoki Soshi sees 4,168 copies sold in its first 4 days whereas the latter title failed to chart in its first week. Nevertheless, between January 17 to January 23, it sold 3,679 copies.
Souzai Saishuka no Isekai Ryokouki Volume 11, an AlphaPolis title, is 11th at 3,708 copies sold. It has a Manga adaptation of the same name published via AlphaPolis Web Manga. You can actually check out its first chapter right here, available in Japanese. According to the cover of its 11th volume, the series now has 680,000 copies in circulation.
