The black-haired maid stared in blank confusion as Ryuuko touched her forehead, before her cheeks colored slightly and she was left speechless for a few moments. Her head was not abnormally hot. Indeed, she seemed to be perfectly healthy, only... with Ryuuko's hand pushing the bangs out of the way, a rune was visible, in what was seemingly black ink, scrawled under her hair. Without deeper knowledge of runes it would be hard to decipher, but it could easily explain the maid's forgetfulness.
