This page outlines Daidōji's relationships with characters in the Senran Kagura series.
Hanzō National Academy[]
Daidōji mainly focuses on mostly everyone in the faction, mercilessly training them to their limits by beating them senseless so they can become strong enough to battle powerful yōmas, like Shin.
Asuka[]
Katsuragi[]
Yagyū[]
Hibari[]
Homura's Crimson Squad[]
Hikage[]
In her Shinobi Girls Heart chapter of Estival Versus, Daidōji was able to learn that Hikage's laid back attitude was key to achieving her full feminism, while Hikage never understood what Daidōji's intentions were. There are no other interactions between these two other than this.
Gessen Girls' Academy[]
Yumi[]
In her Shinobi Girls Heart chapter of Estival Versus, Daidōji was taught by Yumi to talk very cutely like a baby in order to gain her femininity, to which Daidōji learned very well and mastered her cute talk throughout the episodes. There are no other interactions between these two other than this.
Hebijo Clandestine Girls' Academy[]
Rin[]
Daidōji's best friend/eternal rival. The two battle with and against each other so they can grow much stronger than the students, while having a close bond with each other at the same time.
