Yamato relaxed when the rest of the negotiations went more smoothly, subtly shifting back half a step to let Ideo have full centre stage - even if their hands were still tightly clasped. He loosened up the tight control he had of the circle, and the glow of the lines dimmed considerably.

Although, admittedly, Yamato was slowly easing off on maintaining the summoning circle because he could feel it starting to put a bit of a strain on himself. Amon was a powerful demon, the circle was small, and thus unstable despite the Hotsuin efficiency, and Yamato had to do another summoning after this as well. At least they proved that demons could be pulled from alternative worlds - Cerberus's summoning should be easy.

So he gave Ideo's hand a warning squeeze, signalling that he should hurry this up a bit.
