What Happened in Sanda Episode 2

The previous episode revealed Kazushige Sanda's secret identity to others. His connection to Santa Claus became exposed through various circumstances. This revelation changed the dynamic between characters significantly.
Fuyumura's determination to find her missing friend intensified. She pushed Sanda to embrace his heritage and use his abilities. The search for Ichie Ono gained momentum as more pieces of the puzzle emerged.
The episode also explored the dystopian setting's rules. Children face strict monitoring and protection in residential academies. Adults maintain control over every aspect of student life. This oppressive system creates the story's central conflict.
Santa Claus figures were once symbols of hope and joy. Now they're hunted as dangerous threats to the established order. This transformation reflects society's fear of anything that empowers children independently.
Kazushige made a crucial decision to fight for children's protection. He chose to become the Santa Claus that society fears. This commitment sets the stage for his ongoing struggles and growth.
Sanda Episode 3 builds directly on these foundations. The lie-detection ability represents another step in Kazushige's evolution. Fans can anticipate more revelations about the Santa Claus lineage and the truth behind Ichie's disappearance.
