Rui & Senjurō Rengoku from Kimetsu no Yaiba. 

I had this small story in my mind while drawing it (sorry for my bad english-skills): 

Senjurō hates spiders. Killing them with a broom would be easy. Instead, he mustered all his courage to carry the small, white spider outside. His big brother had told him that they were much more afraid of him than the other way around; still, it was unbearable to take it in his hand… the hairs on the back of his neck stood up as the thing moved in his hand while he hurried outside. He heaved a sigh of relief until suddenly a voice broke through the cold. 

“Why didn’t you kill it if you’re so afraid of them?” asked a white-hair boy of the same age. 

Senjurō winced noticeably. “Because … if one day I am in the wrong place at the wrong time, I also hope that someone stronger will be gracious enough to release me instead of killing me.“ 

"I see …” said the white-haired demon boy, watching the spider return to him. And even though he had originally come here to kill and eat the boy, he would spare this weak thing … just as he had spared the spider.
