The season eventually expanded beyond its original core members.

Kasumi, Yakumo, Fuuka, Takaharu, and Nagi were joined by additional warriors and allies as the story progressed.

These characters brought different relationships to the Igasaki family.

The expanded lineup allowed the season to explore multiple generations and branches of ninja training.

It also helped reinforce the idea that the Igasaki legacy was larger than one small group.
