Yukko

Appearance
Yukko is a fairly tall and slender woman in her middle age. She has short, blonde hair and dons the standard uniform for Mamas in the plantations.

Phil
Not long after Phil, Shelly, and a couple other orphans from Grace Field House were sent to live with her, Yukko immediately acknowledged Phil to be one of the smartest children in her orphanage.undefined After some time, Yukko started to notice Phil's strange behavior as he was often seen in a sad and depressed mood. Eventually, the caretaker grew suspicious towards him and it is implied that she called Andrew to visit Phil and investigate.

Trivia

 * In one of the colored pages of Chapter 51, a back view of Yukko could be seen. The color of her hair appeared to be browish red. However, later in the colored pages of Chapter 72, her hair color is changed to blonde.
 * Nevertheless, the caretaker's hair color is considered blonde during her official appearance in Chapter 100.
