Stuck in : Fullmetal Alchemist

Christmas extra : Fullmetal Alchemist x Nanatsu no Taizai !!!

-Merry Christmas!!! I shouted happily in the Rockbell's house, throwing confetti everywhere around me.

Today, it's Christmas Day, and we all decided we would spend it in Resembool. Around the huge table are Ed and Al, of course, Winry, granny Pinako, Roy, Riza, Hughes and his family, Izumi, Sig, Ling, Lan Fan, Mei, Scar and even... Daddy!! We found him just in time and I begged him to come too. But of course everything can't be happening as expected...

-Van Hohenheim, Edward Elric, Alphonse Elric, Izumi Curtis and Roy Mustang, a voice suddenly says from the door, all the sacrifices reunited here, tonight. What are you celebrating? Your future death?

-Father!!! we all shout, getting ready to fight.

But he laughs.

-Calm down, calm down. I came here with my seven children. Why didn't you invite us? We would have done a break in our war!

And we are just like... Well like nothing! Our jaws drop and we stay like this a long time... I swear I even feel the little wind blowing, you know, when it's a huge silence... I try to smile.

-W-Well... Come on! We have enough places after all!

Riza put a hand on her gun, Roy gets his gloves prepared (just in case...), everyone seems very nervous. Huh... Except Ling, who is waving them because he's impatient to eat... All the homunculi entered in the house, and, oddly enough, we begin to chat and talk, like friends. Envy and Ed are friendly hanging out, Lust is giving mode advices to Winry, the Fuhrer King Bradley, Wrath, is laughing with Roy and Riza, Sloth is... Sleeping, Selim Bradley, Pride, is playing with Elicia and Al, Gluttony is doing an eating contest with Ling, before Greed takes his place and also does the contest. In fact, everything is just... Weird. Too weird to be real... And just to be weirder... We suddenly hear an explosion coming from outside and we all come out to check what it is. There is a lot of smoke and I put a hand in my mouth to not breathe it.

-Wh-what's happening...?? I manage to ask though my hand.

-I don't know!! Ed answers.

Height shadows come out of the smoke, one looking like a... Pig. A pig... Wait...

-Huwaaah!! It's cold here!! a voice says.

-Meliodas-sama!! Wait for us!! a feminine voice shouts behind him.

I raise my eyes on the biggest shadow and my mind just guesses who they are.

-Sis, you know something? Al asks.

-The Seven... Deadly Sins... Of Britannia....

The smoke disappears and we can see them all, eyes wide.

-Yo! Meliodas greets us.

-But we are the seven deadly sins!! Envy protests.

-They come from another manga... Nanatsu no Taizai... Or Seven Deadly Sins...

-I see... What are they doing there then?!

-Dunno...

The team come toward them and greets them. Greed shakes Ban's hand, grinning. I notice they are talking about wanting everything in the world or I don't know what... They are greed after all... Envy looks, horrified, at Diane, not understanding how the giant could be the sin of envy, thinking he is way cooler than her. I giggle and put a hand on his shoulder.

-You know, she's stronger than you, even in your original form!

-Not true! he pouts.

He then shape-shifts and takes Diane's appearance.
