Mawata Awayuki

Acting as the seemingly flawless child of her family, this composed and intelligent girl maintains a calm exterior to mask the profound loneliness following her father's passing. She secretly channels her grief into heartfelt postcards sent to Sasame under the pseudonym "Miss Silk." Tragically, her deep-seated sorrow becomes a tool for Fenrir, who exploits her emotional pain to nourish the Great Tree.
