I have forgotten the reason why

It was a question she had heard so many times in the past. In more recent years, people have stopped asking her that question. It seemed like everybody in the underworld concluded that it was a forbidden question. The reason why she stays with Aki, huh? Hino asked her something similar. 

She has truly forgotten the reason why.

"Is that what you came here to ask?" Sumire wondered. 

"I asked you this during our last fight, but we got interrupted. After that, you spent your days nursing Tsueno Mamoru, so I didn't see you again."

Ah, now that answers her question. She did meet him that year. She dated Toh, Ren, and Ru. Since he is asking her that question, it must mean his hostility is directed toward the Holy Knights. If that is the case, then it would make sense for him to join the Black Alice organization. Not many organizations are crazy enough to take down the Holy Knights.

"So, you dislike Aki?"
