二見 憂

The soon-to-be mistress of the Hitogata Settlement’s only hotel, the Futami Inn. Her parents are already gone, so she was raised by the Old Mistress, her grandmother Yoshie. 
She’s the serious, fastidious type, with a strong sense of responsibility.  She’s the most mature of her friends, perhaps because she has to help out at the inn. 
She’s a sweet girl who tries much harder than most to support her one and only family member, her grandmother. 

She can nag at times, but she sticks with her friends, even when they’re acting stupid. 
Naori, who’s also more mature, seems to be on her mind. 

She’s called "Young Mistress" by her friends. 

"...Guriko, you’re bothering Sacchan."
