Well, we already talked about what type of talented 'trainees' TRIGGER Inc., took under their wing, but still, in my opinion, this is the kind of project that could present as more beneficial for a training project than any other, because it simply inspires imagination without extraneous or a pretentious conditioning, instills a initial joy for the medium they could work for... like Shiny Chariot also inspired Akko into admiring what she could do, to the point of her going to the Academia against all obvious hardships just clinging to the wonders she experienced at that show. All in a way someone like Mr. Yoshinari, with his broader, more open view and 'connoisseur' of styles outside the normal reach of their somewhat 'inbreed' industry, could provide.
This seems a work of loving the characters expressiveness in it, loving the process of creating such characters... making them seem alive and putting them in a setting exploiting visually that lively approach. Not as means of putting safer self-inserts of the viewer to direct easily a moralizing message, but as better accomplishing a very own creator's fantasy that absorbs the spectator on their imaginative vision in which these characters are properly rooted into, on that strange world, to explain and hit harder with said moralizing message of (precisely) never ceasing to believe (even if in a fantasy like this one, is a sensible remark)... how those characters in their unique situation tackle such crazy, and splendid, and magical happenings awakens our enjoyment like no other, I think.
