Hey, I'm just curious about "Atragon / The Mysterians" (released Nov. 1997), and "Japanese Special Effects Movie Manga Story: The War of the Gargantuas" (released Aug. 2002), two manga collections released by Hirakata Eikan that are listed at https://wikizilla.org/wiki/List_of_kaiju_comics_and_manga#Toho%2FToho_Eizo%2FToho_Pictures.
It seems you and Les added them to this wiki, but I can't find any information about them (or about Hirakata Eikan in general) out there.
Can you please help me? I'm interested in tracking down copies of these.
