équipEment !! my god my maternal language destroyed at this point ;p

Meh, save the complaining for after you’ve helped with the translation.

I haven’t watched this anime or played the games, so I can’t be too sure on these…

“Armure de l’atome de l’esprit” = “Spirit Atom Armor”

“1/24 équipement de la construction d’échelle” = maybe Babelish for “1:24 scale model”

I don't speak French, but based on what you've written, "l'atome de l'esprit" is probably the artist's attempt to translate the Japanese 霊子 ("ryoushi"), an invented word some translate as "psycheon".

It's supposed to be the fundamental particle of spiritual power, much like atoms (原子, "genshi") were once thought to be for physical objects. I've also seen it translated as "spiritron", but I think psycheon sounds more pseudo-scientific.

Wish I can play them. Never got to play part 1.

Sakura Taisen V's supposed to get released in English next year. Too bad the other four probably never will be.
