The table says Re:Zero − Starting Life in Another World has 44 collected volumes. However, KADOKAWA's official product page shows "Re：ゼロから始める異世界生活 45" with a release date of June 25, 2026. That directly contradicts a total of 44 collected volumes, because volume 45 has already been published by the official publisher.

The table lists 15 collected volumes for Goblin Slayer. But SB Creative's GA Bunko, the official publisher, has a product page for "ゴブリンスレイヤー16" (Goblin Slayer 16). The page explicitly calls it the 16th installment and gives its release date as July 15, 2022. Since an official volume 16 exists, the claim that the series has 15 collected volumes is incorrect.

The table says Alya Sometimes Hides Her Feelings in Russian has 8 collected volumes. KADOKAWA's official book page shows "時々ボソッとロシア語でデレる隣のアーリャさん10" with a release date of July 1, 2025, and describes it as the 10th volume of the series. That means the series has at least 10 collected volumes, so the listed count of 8 is incorrect.

The table lists Guin Saga at 149 collected volumes. But Hayakawa Publishing's official store has a product page for "グイン・サーガ150" (Guin Saga 150), titled Miroku no Te, with a publication date of May 9, 2025. Because the publisher itself lists a 150th volume, the claim that the series has 149 collected volumes is incorrect.

The table says Sword Art Online has 27 collected volumes. But Dengeki Bunko's official series page includes "ソードアート・オンライン29 ユナイタル・リングVIII" with a release date of April 10, 2026. The same page's series list also shows volumes 28 and 29. That directly contradicts a total of 27 collected volumes.

The table says Is It Wrong to Try to Pick Up Girls in a Dungeon? has 20 collected volumes. SB Creative's GA Bunko, the official publisher, has a product page for "ダンジョンに出会いを求めるのは間違っているだろうか21" with a release date of October 15, 2025. The page also calls it the 21st main installment. That means the series has at least 21 collected volumes, so the listed count of 20 is incorrect.

The table lists 10 collected volumes for No Game No Life. KADOKAWA's official MF Bunko J page shows "ノーゲーム・ノーライフ 13" with a release date of April 24, 2026, and describes it as the 13th volume. Since an official volume 13 exists, the listed count of 10 collected volumes is incorrect.
