Ep 12. The Self-Proclaimed Knight and the Greatest of Knights

Subaru and the Sin Archbishop of Pride, Regulus Corneas, are locked in a fierce battle. Subaru, armed with only his Return by Death ability, faces off against Regulus, who boasts a seemingly invincible Authority. It's a battle between two men who believe themselves to be the greatest of knights, and Subaru's determination to protect those he cares for gives him an edge against Regulus' arrogance.

As the two clash, Subaru uses his knowledge of Regulus and his power to stay one step ahead of the Sin Archbishop. But Regulus is not one to be underestimated, and his powers are fueled by his belief in his own superiority. As Subaru repeatedly jumps back in time and tries again, he realizes that defeating Regulus will require more than just strategy – he must also overcome the limitations of his own power and find a way to truly believe in himself.

Meanwhile, outside of the battle, Rem's condition remains unchanged. Emilia and the others continue to search for a way to wake her from her enchanted sleep, but their efforts have so far been in vain. Emilia is wracked with guilt at her inability to help Rem – just as she was unable to help Subaru during his trials in the Sanctuary. But even as she struggles with her own doubts and fears, Emilia remains resolute in her determination to find a way to save her friend.

The Self-Proclaimed Knight and the Greatest of Knights is a thrilling and intense episode that showcases both the strengths and weaknesses of Subaru's power. The battle between Subaru and Regulus is a thrilling spectacle, with both combatants using all their wits and abilities to gain the upper hand. But as the fight drags on, it becomes clear that Subaru's Return by Death ability has its own limitations – both in terms of how many times he can use it, and in the toll it takes on his own mental and emotional well-being.

At the same time, the episode also explores the emotional toll that Subaru's repeated deaths and resurrections have taken on those around him. Emilia, in particular, is struggling with both her own feelings of guilt, and her concern for Subaru's well-being. Despite this, however, she remains determined to help both Subaru and Rem – demonstrating the same spirit of determination and selflessness that has characterized her throughout the series.

In the end, the Self-Proclaimed Knight and the Greatest of Knights is a standout episode that highlights the series' strengths – its gripping action sequences, its well-developed characters, and its exploration of complex themes like self-belief and the importance of human connections. Whether you're a longtime fan of Re:ZERO, or tuning in for the first time, this episode is sure to leave you on the edge of your seat as you eagerly await the next installment of this thrilling fantasy series.
