4th Stage – Cover B

Special cover released for the fourth Blue Lock stage play, given as a purchase bonus during a limited-time campaign.

In May 2025, the production took the stage in both Tokyo and Osaka, and a wave of special bookstore campaigns rolled out alongside it, each offering unique bonuses and gadgets.

At Kinokuniya in Shinjuku and Kuribayashi Shobo in Osaka, fans who purchased any eligible title – from the main Blue Lock series to its novels or spin-offs – were rewarded with one of two stage-play-inspired jacket variants, handed out at random.
