Mc has a pact with Foras. One day, something embarrassing happens, and they re like "omg omg omg I wish I could disappear" and then they go invisible. The problem is they don't know how to turn off invisibility, but they learn alot of secrets about the kings 👀
Oh???? OHHHH
This pact perk would be so crafty too because not even the kings can detect Foras when he's in the room, so MC learns some pretty nifty things about each one of them.
(these are just random secret headcanon's btw for the scenario)
For Satan, MC finds out that he has a destressing room where there's things to break, kick, bite, and so forth. But there's a new area in there where it's a dummy of them in the corner and he sits on it after he's done destressing and he cuddles with it and sleeps which looks mighty fucking weird since he sleeps with his eyes open so MC can't really tell if he is or not lmao.
If they manage to find a way to Tartaros during this time, they observe Mammon having a secret dessert room he doesn't tell anyone but Bimet about. It has very rare desserts from all different kinds of places, even different worlds! They all have a bite taken out of them and stored in special boxes where they don't go bad for centuries. He likes remembering how they taste, how they look.
In Abyssos, it's really hard to track down Beel, but Bael usually can get him on the phone and MC happens to walk in on a very strange conversation one day. So Bael this time is scolding Beel for stealing his clothing, even his dirty laundry because now he has to go and buy new ones. Since the call is on speaker, MC can hear Beel explain that the only reason he does it is because Bael's scent is thick enough to trick everyone else into thinking he's not Beelzebub when traveling lmao. As for stealing his underwear though, he likes how they feel on his skin and doesn't bother to wash them or anything when he remembers to return them.
Sooo this is a bit tricky to use in Hades, because Leviathan knows when Foras is in the room (iirc), so he could easily detect when MC is, right? Nope. He doesn't even notice. This means MC can see what he does everyday. Everything is quite normal, until they notice that Levi tends to undress in front of the mirror and stare at himself and his scars, he traces each one, and then he ends up choking himself while saying MC's name. Unknown to MC at that time but he does this quite often as a de-stressor. But guess who knows that MC is watching currently? Foras. He's the only one who can see MC, another perk of the pact.
Now, Paradise Lost is probably not a good place to be invisible in, ya know just in case you need some medical assistance but this means MC can observe what Lucifer does. Unfortunately he seems absent when they are around but they do stumble on Lucifer's collection of....random photos of Satan? None of them are lewd, it's just random shots of him from above, kind of as if Lucifer took them from his height. There was even one where Lucifer was petting Satan who resembled an angry cat ready to scratch him. Maybe he just finds Satan that adorable he has to keep these images of him. What a strange thing lol
Now MC already knew what to expect being invisible in Niflheim. Not much. Not much at all. Oh wait, what a second...Belphegor sleep talks? He keeps grumbling about random things, also the name of the Kings keep popping up in his vocabulary too. He's revealing some pretty weird habits and kinks he's heard and seen in his mangas and shows. And MC's name? Oh wait...he's having a wet dream?! He's reaching out, does he...know? Nope he was just reaching for a pillow so he can stuff it between his legs and hump it. Okie dokie then.
Lastly...Abaddon. This is a good place to be invisible in as to not draw attention, right? What secrets could MC find in the largest prison in Hell? Well since everyone is locked up, there's not much gossip, which is really boring. However, today is a lucky day for MC because guess who's outside the palace talking with one of the guards? Asmodeus. But just as MC starts to get closer to hear better, the lusty king's head snaps in their direction as he sniffs the air. Well, turns out he can smell MC even if they're invisible. And now it's a dangerous game of hide and seek. But if we remember from earlier, Foras can see them, which means Foras followed them everywhere even here and quickly gets them back to Hades safely before Asmo finds them. Not all is lost though, Foras does have one secret to share that he learned on his own and that Asmo had to get reconstructive surgery one time because his dick was disfigured by him because the person he slept with had teeth in every orifice. And with that...perhaps MC has done enough sleuthing for one day
