Sumire Muroto

Sumire Muroto is an easygoing, charismatic woman. She enjoys playing pranks on Rentaro Satomi, seeing as he is one to be easily scared by eerie happenings. Similarly to how the others around Rentaro call him weak, Sumire is no exception as she shows no pity when naming his faults. Sumire also enjoys toying or misinterpreting Rentaro's words. Despite her carefree and lively persona, Sumire was filled with sorrow when Gastrea first started to take over mankind, stating that not even a thousand words could explain the agony she felt at that time.
