Sakura and Shirou
On hearing the Shaman's agreement, Sakura smiled slightly, and began to chant, holding out her hand in his direction as she did so.
"Bereiten!"
"Ihre Worte wurden gehört, unsere Vereinbarung wurde getroffen. Nun werde ich Sie für immer daran binden. Ihr Wort ist Ihre Bindung, dieses Versprechen wird nicht gebrochen.
Binden, binden, binden, binden!"
As she spoke, he would feel a weird sensation in his chest as the Geas formed, binding him to the promise he had made for as long as Sakura held to her end of the bargain. And, sure enough, the effect was immediate, to the Shaman's apparent surprise. A broad smile appeared on Sakura's face as the haze began to form into the shape of her beloved Senpai, even as the Shaman complained bitterly, his intention to deceive her now obvious.
"Senpai!" Sakura shouted, excitedly. "Are you OK?"
Shirou, suddenly appearing from the weird darkness of the twilight world he had been trapped in, blinked several times, to regain his vision, before running over towards the obviously-concerned Sakura and embracing her.
"Yes, I'm fine, thank you", he said.
The Shaman, meanwhile, glared angrily at Sakura, who simply smiled back, overjoyed to have her husband back.
"What, did you think I would bind myself without even ensuring your compliance?" she said.
However, she still had her side of the bargain to uphold so, reluctantly, she released her hold on Shirou. But, to her relief, Steaven had seemingly finally taken control of the situation, with Nanako's help, rejecting the Shaman. Whilst his words were slightly concerning, particularly his claim that he could dominate others without the Shaman's help, right now, just getting rid of the Shaman was enough for her, particularly since Nanako seemed willing to fulfill his needs if necessary.
"Thank you, Steaven", she said as the Shaman finally vanished, letting out a sigh of relief. "And I'm glad that you've realised that you cannot simply lie to yourself, or hide how you really feel."
"But", she added, "you do seem to be a good person. Please do not forget that."
