Mitsuri Kanroji/Relationships

Obanai Iguro
Obanai is deeply in love with Mitsuri, as he's stated in the manga in chapter 188. He feels as if he can't tell her, however, because of his "filthy blood", caused by trauma in his past. He first saw her when she stood under a sakura tree, which is where he fell in love with her. To show his affection, he gets her gifts, such as food or the socks that she wears in her uniform. Even though she is the pillar of love, she is unaware of his infatuation, causing his love to be unrequited.

In the Dimensional Fortress Arc, she and Obanai fight Upper Moon Four, Nakime, showing impressive teamwork but are unable to beat her before Muzan Kibutsuji kills her himself.

When fighting against Muzan with the other pillars and demon slayers, Mitsuri is injured. Obanai instantly rushes to her side, taking her away from the battle to get help. As he leaves her with the other demon slayers to go back to the battle, she is seen screaming his name, begging him to come back alive.
