Almost every scene in this, to me at least, could always be read with subtext.
The early relationship subtext is that of fresh lovers in the early dating phase.
And it's so captivating!
It works whether it's a master and servant, two friends, or a couple.
It's all about connecting, bridging the gap between each other, lifting each other up...
And it is also reflected in everyone else around them.
Their college mates see them as a fresh couple,
The other Oni see Naori as Hinata's "human mate", with a subtext of either a toy or a ruler's concubine.
The other humans see Hinata as Naori's pet Oni,
And throughout the story, most noticeable with the doctor, you see how they together begin blending everybody's stagnant worldviews and perspectives on each other together.
Just like the reference they occasionally make about mixing things together,
Their upsetting of the status quo is slowly beginning to mix the two mirrored halves, the two sides of the same coin, together.
There are so many layers to what we read in the pictures in this story, it's like poetry.
Unless the ending gets horribly botched, this will become one of the manga I come back and reread several times a year. There's nothing else quite like it, and the way it mixes fantastical mythology with deeply relatable real-life challenges and analogies makes it a riveting read that's incredibly hard to put back down once picked up.
