Talk:S Ultimate Booster 4: Buddy Again Vol.1 ～Welcome Back Heisei Fighters～/@comment-34966512-20190907091849/@comment-43470091-20190907103936

Heisei was the previous era in Japan. Each time a new emperor takes to the throne, Japan goes into a new era, so to say.

Showa was the era in the late 1900s I believe, followed by Heisei, and earlier this year, we shifted from Heisei to Reiwa, with the rise of the new emperor.

I believe.

So "Heisei Fighters" is basically "the previous era of Buddyfighters"
