After overpowering what seemed to be Miyu's Sword Spirit, the resistance that Leo felt completely disappeared as the rest of the procedure continued as normal.
In return for having to put in more effort to deprive her, Miyu's expression was the worst one so far. Clara looked pained, but Miyu looked like she was watching her soul being pulled out of her.
Considering that she was the team's worst, Leo initially planned to keep her conscious during the bone alteration process.
However, she immediately passed out as soon as the process was complete, so Leo decided to spare her the additional pain. After all…
'She should be helpful in her own ways.'
Although he didn't necessarily need her to tell his story, Miyu's statement would do well to solidify the fake image that he was designing.
Besides, if she had indeed understood his false intentions, then he wouldn't have to worry about her grudge at all.
