Miia/Relationship

These are the various relationships Miia has or had over the series.

Kimihito Kurusu
Miia is the first monster girl to move in with Kimihito. They met when Ms. Smith/Sumisu made a mistake when trying to locate Miia to her host family. While they were talking, Miia started to shiver due her being coldblooded, he started to cover her snake half with a blanket and gave her a smile. This act of kindness touched her heart and she's been in love with him ever since.

Kuroko Smith
Ms. Smith is Miia's coordinator, but made a mistake about Miia's host family, so she ending up living with Kimihito instead.

Fellow House Guests
Miia tends to view the other girls living with Kimihito as rivals, yet she seems to be able to live with them peacefully on a day to day basis, as long as they don't get too close to Kimihito. She sometimes insults them, though.

Papi
After discovering that Papi is the same age as her, Miia immediately views her as a rival for Kimihito's affection and regards her with suspicion. However, due in large part to Papi's childlike mentality and general naivety, Miia's wariness of Papi has been diminished somewhat in favor of one characterized by maternal protectiveness.

Centorea Shianus
The relationship between Centorea and her is what one may characterize as a friendly (albeit occasionally heated) rivalry. While Miia sees her as a rival for Kimihito's affections, she genuinely respects Centorea for her integrity and fortitude and often seeks her help when troubled about Kimihito or one of the other girls staying at their home.

Suu
After being assaulted by a dehydrated Suu in episode 5 (while trying to protect her no less), Miia generally views Suu with ambivalence. While she frequently treats Suu with maternal affection due to her childlike nature, Miia views her with suspicion due to her tendency to assault friend and foe alike when dehydrated and signs that she likewise harbors romantic feelings towards Kimihito.

Meroune Lorelei
It is shown that Miia didn't see her as a love rival but still counts her as threat to Kimihito. Because of her "tragic love" fetish Miia is scared that Meroune may cross the line of killing Kimihito.

Rachnera Arachnera
Of all the residents at Kimihito's residence, Miia views Rachnera with the most distrust and hostility (not least because of Rachnera's hobby of regularly tying up the other girls for her own amusement). To exacerbate matters even further, Rachnera is by far the most aggressive in her efforts to seduce Kimihito thereby causing Miia to view her as her most dangerous "love rival". However, despite these feelings of antagonism, Miia does genuinely care about Rachnera as evidenced by her concern in Chapter 27 when Rachnera's original host family (who previously sold her to the criminal underworld) seeks to have her returned to their care.

Lala
Miia doesn't see her as a love rival.
