How? I feel HST is more of a fan abbreviation, mostly with Shonen fans. I used it on the front page news, and some folks don't know what is that because they don't watch Shonen. I had denied wiki submissions for an HST concept page.
HST is just Holy Shonen Trinity (One Piece, Bleach, and Naruto). Chances are it might change with the times as Naruto's manga had ended this year.
