Issei Hyoudou
Issei Hyoudou is the central protagonist of the "High School DxD" series. He is depicted as a high-spirited and somewhat lecherous teenage boy with a strong and straightforward personality. Issei has short, spiky brown hair and brown eyes, often portrayed with a typical high school student's uniform. Initially, he seems like a typical, somewhat perverted high school boy, but as the series progresses, his character depth unfolds.
Issei is known for his unwavering determination and courageous heart, which becomes more evident as he faces various challenges and battles within the series. Despite his often frivolous and lewd behavior, he has a genuine and deep-seated desire to protect and help his friends and loved ones, showing a more noble side to his otherwise playful nature. This makes him a beloved leader among his peers.
Furthermore, Issei possesses the Sacred Gear known as the "Boosted Gear," which is said to house the soul of the Welsh Dragon, Ddraig. This gives him the ability to enhance his abilities exponentially, a feature that plays a central role in the plot and his development as a character. His journey from a simple-minded schoolboy to a heroic figure in a complex supernatural war showcases significant growth and complexity in his character arc.
