Both Hero Gossips and Roman Album made it to Oricon’s weekly general book ranking (this list excludes manga, it has an own list). The figures only include the retailers that Oricon tracks so the actual amount of sold books is probably higher.
23. Tiger & Bunny Official Guide Book Hero Gossips … 13,200 (estimated)
26. Tiger & Bunny Roman Album … 11,757 (estimated)
The first Official Hero Book sold really well, and judging from how fast Hero Gossips seems to be selling it’ll probably reach a similar number, depending on how many copies they’ve printed.
I’m actually having a hard time finding Hero Gossips in stock at the usual outlets where I shop, and Aki was wondering how many of those books have been bought by non-Japanese fans of T&B.
