Episode Highlights
I'm Done Being a Human!
The first episode establishes the series' unique blend of comedy, ecchi, and supernatural horror. It introduces Issei Hyodo, his perverted nature, and his shocking death at the hands of his first girlfriend, Yuma Amano (the fallen angel Raynare). His subsequent resurrection by Rias Gremory sets the entire plot in motion.
This episode is the foundational block for the entire series. It introduces the core concepts of devils, fallen angels, and reincarnation, immediately establishing the stakes and the central conflict of Issei's new life.
I'm Picking a Fight!
The climax of the first season. Issei, having trained relentlessly, challenges the nigh-invincible Riser Phenex to a one-on-one duel to save Rias from their arranged marriage. By sacrificing his arm to Ddraig for a temporary burst of immense power, Issei manages to defeat Riser in a dramatic and emotional battle.
This is Issei's first true moment as a hero. It solidifies his devotion to Rias, proves his potential for growth, and establishes the series' central romance. His victory fundamentally changes his relationship with Rias from master-servant to genuine partners.
Go, Occult Research Club!
The Occult Research Club faces off against the powerful fallen angel leader Kokabiel, who threatens to start another great war between the three factions. The episode features intense team combat and reveals shocking truths about the death of God in the previous war.
This episode significantly expands the world-building and lore, revealing the fragile state of the celestial power balance. It also marks a turning point where the threats become much larger in scale, moving beyond personal conflicts to world-altering events.
Clash of the Twin Sky Dragons!
The leaders of the three factions (devils, angels, and fallen angels) meet for a peace summit, which is attacked by the Khaos Brigade. The episode culminates in the first major confrontation between the two Heavenly Dragons: Issei (Ddraig) and Vali Lucifer (Albion).
This episode is pivotal for establishing Issei's long-term rival, Vali, and introducing the overarching antagonists of the series, the Khaos Brigade. It elevates the conflict to a new level, showcasing the immense power of the Heavenly Dragons.
Any Time, For All Time!
Issei unleashes the incomplete Juggernaut Drive, a terrifying and self-destructive transformation, after witnessing what he believes to be Asia's death. He becomes an uncontrollable monster of pure power, forcing Rias and the others to risk everything to bring him back from the brink by communicating with him through the power of her breasts.
This episode showcases the terrifying depths of Issei's power and the strength of his bond with the girls. It's a dramatic climax that highlights both his immense potential and the dangerous nature of the dragon sealed within him. However, this arc deviates significantly from the light novel source material.
Lion Heart of the School Festival
The culmination of the fourth season, where Issei faces Sairaorg Bael in a highly anticipated Rating Game. The fight is brutal and pushes both combatants to their absolute limits. Issei must unlock a new power, the Cardinal Crimson Promotion, to win. The episode also features Issei finally confessing his love to Rias and calling her by her name for the first time.
This episode represents a major milestone in Issei's character development, both as a fighter and as a person. His confession to Rias is the payoff to a romantic arc built over four seasons, fundamentally evolving their relationship and marking his maturation.
