Took me a while to complete the gallery (no hustle time) as of the latest DLC. Anyone too lazy to unlock the gallery themselves can go to post #27 to get my copy. Usual disclaimer: the files work on my PC but I don't guarantee they work on others. No hustle time, so that scene remains as ???. Everything else is unlocked.
I'm actually impressed by Beelzebub's harem ending. I thought the original game's harem ending did a decent job at revealing the story, but the harem ending in the latest DLC tops it. All of the loose ends have been cleared and everyone's role in the background story is properly fleshed out and concluded.
Props to the VA for Kiriko; I thought she did a really good job both in the H-scenes and in the dialogue scenes for character exposition.
