21 Trio

So The hashiras did secret santa (yeah i know chrismas was over a long time ago, for me at least but still) and if you don't know what Secret santa is its where people in like friend groups grab a name from the Bowl or whatever the names are in and draw a name and they have to get that person a gift for Christmas, but its a secret who gets each other but on Christmas or on the day decided they all say who got who and People open they're gifts they got for each other, Anyways, So The hashiras Purposely gave Them Each others names, but instead of them getting one name each, they got 2, Giyuu got: Sanemi and Obanai, Sanemi: Giyuu and Obanai, Obanai: Giyuu and Sanemi, so yup also, the master said they each got 2 because they did great on a mission recently but it was actually for them to get each other, confusing I know, Anyway, Enjoy!
