There's a soul loitering outside Ikebukuro, drifting aimlessly, like it's watching the life be sucked out of the city. God. This is just a gorgeously evocative line, and a really strong opening.
The shimmering green light of her Dia fills the air, crisp-smelling like freshly broken bamboo. I love the sensory detail, because I love seeing how people flesh out magic like this. I also really like that it's Kikuri-hime, and not one of the more awkward configurations that also know Dia.
Obviously I've not played this particular game so I don't know the details of this, but I really like the interplay of demon and not-demon in Naoki, and how intimidated Isamu is by the brokenness of the world. Lovely.
