One of the key strengths of the High School DxD dub is its cast. The main characters, including Issei Hyoudou (voiced by Bryce Papenbrook), Akeno Himejima (voiced by Erica Mendez), and Koneko Toujou (voiced by Monica Rial), are well-voiced and bring depth to their respective characters. The voice actors have done an excellent job of conveying the characters' emotions, from Issei's enthusiasm and determination to Akeno's kindness and compassion.
