It's "only" an anime movie rather than a series, but "Jin Roh" has no plot armor.

I think "Mononoke-hime" (again a movie) could also count. While the curse is making the main-char strong, it doesn't boost his resilience to wounds.

"Magi", while maybe not completely free of it, at least has very little plot armor. There the mains survive and defeat enemies with abilities that make sense.

"Gundam 8th MS Team" has no plot armor. Even though the protagonist sits in a Gundam, he's still almost beaten by a Zeon ace in a technically inferior Mobile Suit and only manages to win, because that ace went after the mission objective, instead of the guards due to time preassure.
