An anime project of manga Blood Lad was leaked by the cover note on Young Ace magazine's July issue that was listed on Kadokawa's website. The cover note announced a special collaboration project of Suzumiya Haruhi's new novel. The cover picture of Young Ace was immediately replaced with one without the announcement of the anime project probably because it was a premature leak.
