Sister ni Natta Onna Kishi no Hanashi////

Kukkoro changes from a female knight dressed in strong armor to a highly exposed sister, prioritizing her talent for recovery magic. Although she is conflicted between her pride as a knight and the sacred magical power that becomes so powerful that she wears light clothing, she uses her heart of love to subjugate monsters in order to serve her beloved hero Brave!　

Don't give in to naughty happenings, Kukkoro♪
