Rode accepted Olivia's invitation with a mix of anxiety and surprise.

He hadn't really intended to go; Olivia was just too much like a big sister. She was tall, even taller than Rode by a third of a foot. Standing before her, he only reached a little below her chest, and looking up at her was quite intimidating.

Moreover, after advancing to the king-level, she was always surrounded by an almost imperceptible aura of majesty, like a sovereign holding power.

Perhaps that's why humans named this stage "king."
