Oh great, more anime crap...
I'm interested.
OKAY, BUCKLE DOWN BECAUSE YOU'RE IN FOR A RIDE
Garo is a tokusatsu series, with monster design by Keita Amemiya-- who did creature design for SMT4
It's about the Golden Knight-- the titular Garo, as he fights the monster of the Week, called Horrors and overthrows whatevere major plot the series runs on. The animation is about Leon Luis trying to settle a vendetta and stop the mad Makai Alchemist, Mendoza, from doing a bad thing and becoming immortal, while also avenging his mom.
By the way, Leon was born during his mother's burning at the stake.
Consistently, Garo is a series about inheritance. What the next generation takes from us is important, so we have to protect the world so they don't have to clean up our mess, and just because someone is gone, they aren't erased. You and everyone they met was affected by them, and they will keep the memory of the departed going, from generation to generation.
Divine Flame, is a fantastic film about the freedom of choice, but more importantly, how we have to let people go. The dead must rest, and we must not try to fight against the natural way of things. It's a film about grief and accepting it, but how we have the choice on how to deal with it!
