Mc: Remember when I told you about my period?
The brothers: ...
Mc: And how it was recommended that for those days there should always be chocolate and hot water bags because it helped me and gave me comfort?
Satan: Yes, we remember it...
Mc: And remember that I told you so you would not be caught off guard?
Belphie: Yeah...
Mc: Well *taking a breath*, it's time for us to talk about YOUR periods.
Mammon: We do not have periods!!!
Mc: *slamming the table* Periods, heats, mating time…. Call it what you want but it's time to talk about it!!!!
Levi: *very flushed* But...
Mc: But nothing!! I'm tired of waking up in nests in random places in the house time to time!!!! It's not nice to wake up with feathers in my mouth!!!!!
Lucifer:*blushing*...
Mc: I would also like to be prepared in case I find any animal corpses at the foot of the bed!!! I appreciate the thought but I am human!!!! I don't need you to show me that you can get resources!!!! That's what supermarkets are for!!
Satan: *dodging the gaze*
Mc: And it would really be nice to know when you produce pheromones, that would have avoided me a lot of problems in RAD.
Asmo: Ha, ha *nervous laughter*
Mc: Or to know when to prepare myself to wake up in a cave dug in the garden or underwater.
Beel: ...
Levi: ...
Mc: And it would not be bad to know that during your period you are showing your demonic forms, I almost had four heart attacks the first time I saw your eyes glowing in the dark Mammon!!!
Mammon: That was an accident...
Mc: *enumerating with their fingers* Or that your sleep schedule changes, or that you don't sleep at all, or that your temperature changes, or that some of you become non-verbal, or that your wings produce a specific sound as a call…
Lucifer: Enough *massaging his temples while blushing* It has become clear.
Mc: You didn't think that, as a human living with seven demons, I should know these things???
Mammon: We didn't think you would notice...
Mc: *looking at him exceptionally* Mammon, my dear, last time you brought me a cocatrix egg because it glowed.
The brothers: ...
Mc: This is my last warning! Either we talk and set schedules or I take Solomon and Luke and go live somewhere else.
The brothers: !!!!
Satan: *whispering* Why only Solomon and Luke?
Asmo: *also whispering* Mc has given this same talk to Lord Diavolo, Barbatos and Simeon….
Mc: *taking out a notebook* So stop behaving like a pubescent teenager and tell me how your periods are going and if I can help you in any way.
Lucifer: Okay, you win…but this is not like your period.
Mammon: It's not fair!!! It's not like we can avoid it
Levi: *covering his face* This is going to be worse than a public exhibition…
Asmo: Well, at least this way we won't have to hide it….
Satan: *sighing* Will it really do any good?
Beel: *worried* It won't be a problem for Mc?
Belphie: … Well, I do want them to spoil me on my period.
The brothers: Belphie!!!!
Mc: *holding back laughter* That's the spirit.
