You think he has Nei's pantsu tucked in his back pocket or something? He probably can only transform into Kyouka's slave because he is contracted into her.
The real fucking question is why doesn't Himari use slave on Ren or Aoba because her contract is an imitation and thus shouldn't be required to follow the "slave till death" rule Kyouka seems follow.
Clearly, it's because Himari's homophobic.
