Mitsuba appears to be a regular mother, supportive of her young daughter's dream career until she grows old enough and begins forcing her to follow a more practical path in order to make a living.
After her elder daughter goes missing after arguing with her, she became depressed and later delusional, mistaking her younger daughter as the already deceased, elder daughter.
