- “I want to defeat Muzan, and then die. I pray my impure blood is somehow cleansed. I want to be reborn into a peaceful world without demons. And then next time, I can tell you I love you.”
- — Obanai's internal dialogue to Mitsuri, Chapter 188
Obanai is deeply in love with Mitsuri, ever since he saw her in a kimono under a sakura tree. He's strongly protective of her and dislikes it when other people/demons call Mitsuri dumb or air-headed. Obanai also became jealous when Tanjiro said he spent some time at Mitsuri's estate and was extra hard on him during training.
They fought UM4 together, demonstrating impressive teamwork but still failing to take down Nakime, who was killed by Muzan instead. The duo then join Tanjiro and Giyuu's battle against Muzan.
When Mitsuri gets injured, Obanai is by her side immediately and orders a nearby demon slayer to take care of her before returning to the battlefield. As he leaves, Mitsuri cries out his name and begs him to not get killed; Obanai's bandages around his mouth unravels and his disfigured mouth is revealed, but he ignores it in favor of avenging what Muzan did to Mitsuri.
In the fandom, they’re shown getting food or eating a lot because of Mitsuri’s love of food. There is also a notably heavy dose of angst and fluff in ObaMitsu fanworks, mainly because of Obanai's dark past and his facial deformity. Works often have Mitsuri comforting Obanai and being his pillar of support when his past bothers him.
- The socks Mitsuri currently wears were a gift from Obanai.
- Although they are often drawn eating together, Obanai never eats with Mitsuri because he doesn't want to scare her with his scars.
