I do not own any of these characters… Ms. Takahashi does. This is my first attempt at something like this, so I hope you enjoy it!
This is a little moment of Rin and Sesshoumaru from ep.s 115, 116 wherein Rin is kidnapped by the Schinintai and Sesshoumaru enters the sacred barrier, risking his own well-being as the force severely weakens or "purifies" youkai, to save her.
Rin's heart was still racing from all that had happened. She'd seen a man called Suikotsu turn from evil to good, and then chose to turn to bones and dust. A beautiful miko had arrived to save her when Sesshoumaru could not. Yes, Sesshoumaru-Sama had come for her, but something about this time was different…
"Rin – we're leaving."
"Hai!" Rin bowed to the miko and hurried after him, leaving the scene of battle behind. Walking at his side his side Rin gazed up at Sesshoumaru, and as usual he stared straight ahead. He was always silent, but something about his silence felt unusual to the child. In the silence of the mountain Rin's attention was drawn by the soft rustle of fine silk brushing against metal armor. Unconsciously her small mouth parted in surprise when she noticed a trickle of blood running down his wrist and dropping off the tip of his claw. Her eyes followed the stream upwards to find the fine silk sleeve stained with blood. She almost extended her small hand to touch the spot when she noticed another sound, soft and barely perceptible; uneven breathing. With wide eyes she though she saw a bead of sweat travel across his red markings on his cheek –
Suddenly the daiyoukai's knees seemed to betray him, and Sesshoumaru reflexively steadied himself with his one arm on the nearest thing. Rin braced under the weight of his hand on her shoulder and looked into his eyes for a moment — surprise, shame? – before quickly securing her two tiny hands tightly onto his and taking a step forward, careful not meet his stare.
She felt his eyes on her for a moment more before they continued in silence down the mountain, through the mist; proud youkai lord and the little girl as his crutch.
The ethereal quiet was broken by a croak up ahead, "Oh this barrier! ... Is there no end to this suffering?!?" Jaken was lying on the ground waiting for his master.
Rin drew her hands back and nimbly jumped to the other side of her protector.
Jaken saw their two forms coming through the mist and jumped up, "Amazing, as expected Sesshoumaru-Sama! Your great strength cannot be stifled even by such a holy barrier!"
Rin finally looked up at Sesshoumaru for the first time since his strength had failed him. If she had blinked she would have missed him returning the glance from the corner of his eye and nodding to her ever so slightly.
