Aster used Rigel's flames to clean the blood on the blade of his sword, as he was about to do the same with the corpses, he noticed they all had different grades of burns which originated from the place where Sarina's spirit energy cut them.

Some only had a few, while others were completely covered in ash-red burning marks, after a few seconds everything but their bones disappeared, leaving behind skeletons with weird symbols engraved on them.

Aster gave Sarina a questioning look, but apparently, she was as surprised as him, so he left the subject for later, then his attention changed to Kana, although there was a glint of an uncomfortable light in her eyes, she was calm and composed.

Noticing Aster's gaze on her, Kana smiled before saying.

"Big brother wouldn't have killed them if they didn't deserve it".
