Acedia is a young girl with a fair complexion and short blue hair that cover her eyes. When revealed, her eyes are bright caramel. According to the 2017 November calendar, she has twintails with pom-pom hair ties underneath the hood.
Introverted with a weak constitution. Acedia is shy and keeps to herself, often looking sad or apprehensive. She has a surprisingly scary side to herself if pushed enough.
In the Merry Christmas stage, she seems to gain a lot more confidence when she's fighting.
Shyly Acedia shifts her foot and turns to the opponent before speaking. She appears unsure of herself while snowflakes appear around her.
Her ears are seen behind a snowman as she peeks out of the snowman before appearing in front of the snowman as she shyly reveals her book.
