Hiei rushed in and face-tanked an American Fleet in the first Naval Battle of Guadalcanal, and nearly survived it, had she not been abandoned she might have. Tough girl = higher armor.

Kongou's second-tier toughness probably represents the reinforcement she received during a drydocking mid-war.

Haruna was the last surviving member of the sisters, and weathered several bombing attempts but ultimately sank in shallow water.

Kirishima basically did the same thing Hiei did a few nights later, but didn't even nearly survive it and sank in Ironbottom Sound. She crippled a much higher-tech battleship, though, so she gets high Firepower instead.
