In the thirteenth episode of Ragna Crimson, which marks the beginning of the second part of the season, a tense confrontation unfolds at Starlia's base, where her forces are caught off guard by the arrival of several humans seeking refuge. The events take an unexpected turn and escalate quickly as Ike recognizes the threat posed by the humans under Otto Zora's influence and warns of their potential hostility. The scene grows darker as Starlia intervenes, demonstrating her resolve to protect her ranks and repel threats by making it clear that she will tolerate no form of betrayal or danger.

Starlia's leadership is put to the test as she divides her team, sending Greya, Hesela, Chris, and Nazarena to scout the forest—a move that highlights her strategic foresight and the importance of gathering intel. The narrative then shifts to Otto Zora's anticipation, as she impatiently awaits her confrontation with Starlia.

The episode delves deeper into the complexity of the dragon world, focusing on the higher dragons and their varying power levels, which are determined by their maturation period. Simultaneously, a fierce battle erupts between Ragna and Taratectora.

Meanwhile, the aerial reconnaissance conducted by Greya, Hesela, and the air unit introduces a strategic element of surveillance and intelligence-gathering, which proves critical for Starlia's forces to maintain the upper hand.

Throughout the episode, multiple perspectives are interwoven—from Zora's tactical manipulations to the courage of Starlia's forces and Ragna's personal struggles. The introduction of lesser dragons as Taratectora's strategic ploy and the subsequent intervention of Shin and Garm to aid Ragna add further layers to the conflict.

The episode also explores the backstories and motivations of the characters, particularly through a flashback featuring Starlia and Shin.
