Rhode was glad that his younger sister was the only one keeping watch, or else his life's work would be over. He forgot the fact that the core projections would absorb the sub-personalities after killing them, which meant that he would also take in his other self after slaughtering him. But what he didn't expect was for his other self to manifest after being absorbed. This left Rhode feeling helpless and upset.
Well, these were trivial matters, after all. The most important thing was the relationship between him and the holy sword card spirits. Even though this experience lasted only one night, to his subjective consciousness, he felt as if months had passed. Thus, after exchanging pleasantries with his younger sister, he couldn't wait to send her away. But when he saw her smile before she left, he knew that this would become part of his dark past…
But at least she's my younger sister, so she can't possibly use that against me, can she?
