It's the Ise. I saw the Pixiv tag for the class, but missed the sub commentary. I'm bad about that.
Ooh, the commentary wasn't there before, and I didn't bother to take a look at the Pixiv tags and commentary.

There's a CV on the horizon though.
Island superstructure, definitely a CV. Oddly it's on the port side instead of starboard. IIRC only Akagi and Hiryuu had that configuration, out of all the IJN CVs.
