As @Arete said, Iām glad they stuck to one thing this episode. They portrayed her past quite well, to my memory at least. The introduction of Imamiya also felt quite natural and well done compared to the other introductions that had to be changed around.
The two main issues I had with this episode were the song placement, and that oddly thrown-in bit with Lucia at the end. As for the song placement, I heard Radiance, Scattered Flowers, and Scene Shifts There all within, what, a 10 minute span? It felt so odd and jumbled. Their use of Koibumi wasnāt bad though, considering they probably wouldnāt have had another place to use it.
The bit with Lucia definitely seems to point at her getting this treatment next. Although, slapping it at the end of the episode like that was plain awkward, and ruined the tone and feel they had build up, in my eyes.
In any case, outside of those two things, I really enjoyed the episode. We got Esakaās classic line, more Shizuru, Imamiya, and even Yoshinoās Wolf pack.
