This page deals with Lala's interactions with the other characters.
Humans
Kimihito Kurusu
Her relationship with Kimihito is more complicated than the other girls. Whereas many of them are trying to win his hand in marriage, Lala seems to have no interest in the matter. However, she does tell Kimihito when he dies his soul belongs to her due to her duties as a dullahan; though this could mean she is willing to wait until the end of his natural life, no matter the length, to be with him, showing an incredible amount of patience when compared to many of the other girls with whom she lives. Or it could mean that she is just interested in him sexually.
Though her body seems to be a lot more honest about her feelings towards Kimihito; when Kimihito crashed into her, the body became aroused and happily embraced him while the head looked on in embarrassment.
They get along very well and share a special bond. Whenever she is distressed she seeks him out for advice or comfort, and is lot more honest and open about her emotions. When she was worried about Yuhi she came to him for help with her "Social Anxiety". Even going so far as to give him a near death experience just to have a private conversation with him.
She seems to be a little more klutzy around him; Once appearing in his room while changing her clothes and later appearing naked in his shower. It's unknown why she chose those specific locations.

Yuhi
A close and personal young friend. They get along very well and she treats her like a little sister or even a daughter. She enjoys showing off her Chunni act to entertain her.
