So first off

Devs...please...please let us romance Mephisto, Thirteen, and Raphael

And

I just found this very funny and cannon for Mammon now.

Secondly

Aside from this very last bit from the post credits...kinda underwhelming finally.

The brothers stay, Raphael leaves without a word after they give their decision, everyone knowing full well the Celestial Realm threatened war, you're still stuck in the past and will be an exchange student at RAD with Solomon (I see you retconnning Devs! You can't fool me!!), and it ends with a 6-8 lesson ball.

Interestingly, when Diavolo bestows your new title (Devilsitter) and you're given a forehead kiss there is a white flash.

We always get fade to black whenever we're kissed. Or just the background.

White flashes are our soap opera stereotype signaling something important is about to happen or did.

And Diavolo brought up future of Devildom a few times

Overall, my rating of the story 7.5/10. We got a shit ton of lore which I love about how things came to be in the first game and even new info like Solomon and Diavolo's personal issues and their struggle with them. Like how Diavolo feels he's not ready to be the leader of the Devildom and there is a lot a pressure placed on his shoulders to be the best from his family's legacy.

But...there are times where the stakes where high and kinda dropped. Like the mid-season climax where Lucifer and the brothers confront Diavolo, Diavolo's king's gambit whatever, you in a coma, war with the Celestial realm looming, you possibly being banished.

Now the first part was handled well, I think.

Diavolo'a trial was important, I just wish it was more challenging for him and not just him addressing his Daddy issues and insecurity. But we did get to make out with him, so...horny points, but also it was nice seeing Diavolo being open with MC. Opena and honest. Which is something he’s tried to do in OB (I’m only up to lesson 49 I don’t know how everything or what else happens from then on).

Coma, boring. The threat of banishment is a constant in the background of the first half. And the whole threat of war...completely dropped.

I mean we had a possible interaction also with Michael and for sure Nightbringer. Solomon knows who Nightbringer is (I believe this is reviled in one of the hard lessons and I’m only up to 11 on) and is being very guarded over his own history, yet desperately wants you to ally with him. Well sorry my dude, the brothers are offering me free love and cock while you

Sorry, the whole professor teacher/student role playing shtick ain't my kink

So

Off with you, creepy old man (no offense to those who like him, you do you, more power to you).

I want Lucifer, Satan, and Diavolo to tell me everything will be safe and alright while railing me. And they offer their love unconditionally (I’m not here to debate Diavolo’s questionable actions let me love this himbo prince in peace!).
