Kuroko Smith/Relationship

As a Cultural Exchange Coordinator, Smith interacts with many people and is normally responsible for bringing homestays and extraspecies individuals together.

Kimihito Kurusu
Smith is assigned as Kimihito's exchange coordinator. This makes her responsible for making sure Kimihito is following the Cultural Exchange Between Species Bill and that all extraspecie girls under his care are well and happy. Despite the responsibility of her position Smith treats Kimihito very informally and often takes advantage of his kindness. Smith often visits his household to check up on him and his homestays, constantly reminding him of the prohibitions and its consequences of the law as she was the one who often made him the host of a number of extraspecie girls. Due to her being quite irresponsible, Smith only shows up when the situation is inconvenient for him; often providing information when its too late and has a tendency to mooch off of Kimihito for free homecooked meals. She tends to manipulate Kimihito through threats based on the Cultural Exchange and its prohibitions and will normally ignore any complaints he has when she does so.

Despite her irresponsible and somewhat lazy behavior, Kimihito is grateful for her assistance and protection. He does become rather annoyed and frustrated with her constantly waiting until the last minute to inform him with needed or important information concerning his homestays, random/new subspecies he happens to encounter, when his own house is remodeled, food supplies and finances/expenses; but he is never unkind to her. Smith appreciates Kimihito's willingness to care for the extraspecies he was given and he appreciates her acting as a "guardian" to him whenever he is in trouble. As a result Kimihito will usually put serious thought into the advice Smith does give him. While Smith does not seem to have serious romantic feelings in Kimihito, she is not above flirting with him and calling him "Darling-kun" because teasing him amuses her.

Miia
Smith is the coordinator who was responsible for choosing a host family for Miia. Smith would place Miia with Kimihito, despite the young man not being of the exchange program, let alone Miia's correct host. Despite her negligence in Miia's placement, Smith seems to genuinely care about Miia's well being and happiness, as she encourage Kimihito to study snake ecology so he could make Miia comfortable and encouraged Miia to talk to Kimihito after he hurt himself protecting her.

Miia seems to respect Smith's authority as a coordinator but also recognizes Smith's laziness and negligent attitude, leading Miia to label Smith as a woman who "does whatever she wants". Miia's feeling towards Kimihito can also cause her to become jealous whenever Smith seems to have an interest in him. Smith recognizes this and avoids actively flirting with Kimihito, but she will still tease both him and Miia when she sees a good opportunity.

Polt
Smith seems to be good friends with Polt. When Kimihito and the girls living with him needed to get into shape Smith immediately recommended they use Sports Club Kobold in order to help Polt test her new business. In return when Smith requested the use of Kobold Stadium, so that Centorea and her mother could duel legally, Polt happily allowed her to borrow the entire stadium without any questions. During said event the two teasingly offered play-by-play commentary and seemed to work very well together, much to the annoyance of the duel's participants.

Smith seems to trust Polt a great deal as the Kobold is usually left in charge of extraspecie individuals that Smith puts on probation with virtually no visible oversight.
