The fifteenth episode of "Ragna Crimson" begins with Ragna's devastating annihilation of the dragons, setting the tone for the battles to come. At the same time, Starlia demonstrates her leadership qualities and quick thinking by providing her troops with strategic direction.

Zora, one of the primary adversaries of the dragons, expresses disbelief at the resilience and strength of Starlia's forces. His dialogue with Taratectora not only reveals their strategy but also introduces the concept of powerful spells with long charging times. As the battle continues, the narrative shifts focus to the camaraderie and evolving relationship between Ragna, Shin, and Gram. Ragna's initial insistence on killing the dragons alone meets with Shin's resistance, leading to a moment of reflection and an apology from Ragna.

The escalation of the conflict, as Zora unleashes the fully grown dragons, adds further intensity to the episode and showcases Ragna's impressive abilities. However, it also highlights the frustration of Shin and Gram, who yearn to prove themselves in battle. The episode concludes with Majo's unexpected display of power, thwarting Crimson's plans and foiling her use of hypnosis magic.
