Kuoh Academy believed the Crimson Dragon Emperor had vanished forever, leaving their town in peace. They couldn't have been more mistaken. Hyoudou Issei, the legendary pervert blessed with dragon power, disappeared without trace during an enigmatic confrontation. The entire school assumed death claimed him in some catastrophic event. Reality proved far different. Issei wasn't killed—he was transported across dimensions to a harsh realm teeming with sorcery, supernatural creatures, tyrannical overlords, and remarkably well-endowed female warriors. Survival became his instinct. Training shaped his body. Determination forged his strength. Within that other world, he pushed beyond mortal limits, achieving enough power to challenge celestial beings, topple empires, and possibly seduce a Demon Lord's offspring. (Entirely unintentional... mostly.) Three extraordinary years have passed. Issei has returned. Yet this isn't the perverted teenager obsessed with anatomy anymore. This version carries forbidden techniques, enhanced intellect, and a somewhat improved focus—although his legendary fixation remains intact, now paired with the ability to level entire landscapes in the process. The supernatural factions—devils, celestials, fallen angels—remain unaware of the catastrophe approaching their doorstep. Companions question whether reconciliation, retaliation, or self-preservation suits them best. Those who dismissed him previously? Dress Break evolution awaits their reckoning. An upgraded, unhinged, and insatiable Crimson Dragon Emperor. A world spiraling toward annihilation. And an impending tempest of hilarity, passion, fan service, and overwhelming supernatural ability is prepared to unfold. Brace yourselves, Kuoh. The Red Dragon Emperor returns alongside his expanding collection of devoted companions.
