Reinforce Rule 34

Reinforce is a character from the Lyrical Nanoha series, first appearing as the central antagonist of the A's storyline before later becoming a Unison Device bonded to Yagami Hayate. She is a tall, composed figure with long grey hair, striking red eyes and a dark, flowing outfit, and she carries an air of quiet dignity and sorrow. In later appearances her legacy continues through Reinforce Zwei, a smaller companion device. Fan artists most often depict her alongside Reinforce Zwei, Hayate, Signum, Vita and Shamal, drawing on the familial and protective bonds she shares with them. Common motifs in the gallery include paired compositions of two girls, warm smiles and blushes that soften her stern image, and attention to her long hair, blue-eyed alternate portrayals and jacket details. Artists tend to emphasise the contrast between her imposing presence and the tenderness she shows toward those she protects.
