Whether you’re a longtime fan or just starting the anime, this guide covers many of the most important characters in High School DxD and explains why they stand out.
High School DxD Characters List
1. Issei Hyoudou
Issei Hyoudou is the main protagonist of High School DxD. At first glance, he appears to be an ordinary high school student with big dreams and an easygoing personality. However, his life changed forever after he was killed on his first date and later revived as a Devil by Rias Gremory.
As the wielder of the Boosted Gear, one of the legendary Sacred Gears, Issei gains incredible power over time. His determination, kindness, and willingness to protect his friends help him become one of the strongest characters in the series. Throughout the story, Issei grows from an inexperienced fighter into a respected leader capable of facing powerful enemies.
2. Rias Gremory
Rias Gremory is one of the central characters and the heiress of the prestigious Gremory Clan. She serves as the president of Kuoh Academy’s Occult Research Club and becomes Issei’s master after reincarnating him as a Devil.
Known for her intelligence, compassion, and exceptional magical abilities, Rias is admired by both allies and rivals. She specializes in destructive demonic power and consistently proves herself as a capable leader. Her close relationship with Issei develops steadily throughout the series and becomes one of the anime’s main storylines.
3. Akeno Himejima
Akeno Himejima is the Queen of Rias Gremory’s peerage and one of the strongest members of the Occult Research Club. Calm, elegant, and highly skilled in combat, she combines lightning-based magic with impressive physical abilities.
Despite her cheerful personality, Akeno has a complicated past connected to her heritage as the daughter of a Fallen Angel. Her character development explores themes of acceptance, forgiveness, and personal growth, making her one of the series’ most beloved characters.
4. Asia Argento
Asia Argento begins the story as a former nun with extraordinary healing abilities. Her Sacred Gear, Twilight Healing, allows her to heal nearly any injury, making her an invaluable member of Rias’ team.
Asia is gentle, caring, and deeply compassionate. Although she lacks offensive abilities early in the series, her courage and unwavering support for her friends make her an important part of the group’s success. Her friendship with Issei also plays a major role throughout the story.
5. Koneko Toujou
Koneko Toujou is the Rook of Rias Gremory’s peerage. She is quiet, reserved, and rarely expresses her emotions openly, but beneath her calm exterior lies tremendous physical strength.
As the series progresses, viewers learn more about her mysterious past and her connection to the powerful Nekoshou race. Koneko gradually opens up to her teammates and becomes increasingly confident in both her abilities and her relationships.
6. Yuuto Kiba
Yuuto Kiba serves as the Knight in Rias’ peerage and is considered one of the most skilled swordsmen in the series. His friendly personality and calm demeanor make him popular among students at Kuoh Academy.
Behind his cheerful appearance is a tragic history involving Sacred Gear experiments. His personal journey focuses on overcoming past trauma while becoming stronger alongside his friends.
7. Xenovia Quarta
Originally introduced as a Holy Sword wielder working for the Church, Xenovia Quarta eventually joins Rias Gremory’s peerage after major events reshape her beliefs.
She is known for her exceptional swordsmanship, confidence, and straightforward personality. Xenovia constantly pushes herself to become stronger and quickly becomes an important ally in many battles.
8. Irina Shidou
Irina Shidou is Issei’s childhood friend and a dedicated Angel who works to maintain peace between different supernatural factions. She possesses strong faith and a positive outlook, often bringing optimism to difficult situations.
Although her beliefs sometimes differ from those of the Devils, Irina values friendship above conflict and plays an important role in strengthening the alliance between former enemies.
9. Rossweisse
Rossweisse is a former Valkyrie from Norse mythology who later becomes a teacher at Kuoh Academy. Despite being an incredibly talented magician, she often finds herself in humorous situations because of her practical and somewhat awkward personality.
Her extensive magical knowledge and combat experience make her one of the most dependable allies during dangerous missions.
10. Ravel Phenex
Ravel Phenex is a member of the famous Phenex Clan and eventually becomes one of Issei’s most trusted supporters. Intelligent and highly organized, she frequently manages important tasks behind the scenes.
Although she isn’t always on the front lines, Ravel’s strategic thinking and loyalty contribute significantly to Issei’s growth and success.
11. Vali Lucifer
Vali Lucifer is one of the strongest rivals in High School DxD. As the wielder of the Divine Dividing Sacred Gear, he possesses immense power capable of matching legendary opponents.
Unlike many villains, Vali is motivated primarily by his desire to challenge powerful enemies rather than by evil intentions. His rivalry with Issei leads to some of the anime’s most exciting battles.
12. Ddraig
Ddraig, also known as the Welsh Dragon, resides within Issei’s Boosted Gear. Initially appearing only as a voice, Ddraig gradually develops a strong partnership with Issei.
His wisdom, battle experience, and immense dragon power help Issei unlock increasingly powerful transformations throughout the series.
13. Azazel
Azazel is the Governor General of the Fallen Angels and one of the franchise’s most knowledgeable characters. Rather than seeking endless conflict, he works to create peace between the supernatural factions.
His fascination with Sacred Gears leads him to mentor Issei and other young fighters, helping them unlock their full potential.
14. Sirzechs Lucifer
Sirzechs Lucifer is Rias Gremory’s older brother and one of the Four Great Satans. Widely regarded as one of the strongest Devils in existence, he combines overwhelming magical power with remarkable leadership.
Despite his immense authority, Sirzechs deeply cares about his family and often supports Rias in her personal decisions.
15. Sona Sitri
Sona Sitri is the student council president at Kuoh Academy and the heiress of the Sitri Clan. She is known for her intelligence, discipline, and tactical brilliance.
Her rivalry with Rias remains friendly, and both leaders often cooperate to protect their friends and maintain peace.
16. Great Red
Great Red is one of the most powerful beings in the High School DxD universe. Existing beyond the normal world, this legendary dragon possesses unimaginable strength and symbolizes limitless power.
Although Great Red rarely becomes directly involved in events, its presence greatly influences the series’ larger mythology.
17. Ophis
Ophis, the Dragon God of Infinity, is another legendary figure whose existence shapes many major storylines. Initially associated with powerful antagonists, Ophis later reveals a far more complex personality than expected.
Her incredible abilities make her one of the strongest entities introduced in the franchise.
Why These Characters Stand Out
One of the biggest strengths of High School DxD is the balance between action and character development. Nearly every major character receives a meaningful backstory, personal growth, and memorable moments that extend beyond battles. Friendships evolve, rivalries deepen, and alliances shift throughout the story, keeping the narrative engaging across multiple seasons.
Each member of the cast contributes something unique, whether through powerful abilities, emotional storytelling, comic relief, or strategic thinking. This variety is one of the reasons the series continues to attract new viewers while maintaining a loyal fanbase years after its debut.
