Erina Shindou

Erina Shindou is widely recognized as the exemplary Student Council President of Yotsuki Academy, admired by both faculty and peers for her graceful demeanor and exceptional capabilities. However, beneath this polished exterior lies a starkly contrasting nature—an intense masochistic disposition paired with a fervent admiration for heroes. Since joining the Twin-Tail Squad and transforming into 'Tail Yellow,' her suppressed true self tends to surface dramatically during battles, particularly when struck by enemies or reprimanded by allies, unleashing formidable combat prowess that consistently surprises those around her.
