So both doujin's mentioned Shimakaze being very fast, but looking at her stat on the KanColle wiki she's listed as simply fast...is there something to that one? Or is it simply because she's considered one of the strongest DD?
In reality Shimakaze maximum speed could reach 40.9 knots, the fastest during the war time. So in the game she's very proud of her speed. A lot of dialogue in the game has some relation to reality. Though in reality, Shimakaze did evade all torp and gun shots, but in the end sink herself because of engine explosion due to overheating...... Well, since Shimakaze was fatally flooded at that time, it's not confirmed whether the cooling system was overrun or damaged.
Hence her sinking quote 「速いだけじゃ…だめなのね…」, having only the edge of speed is not the way.
