It was a party celebrating rias and millicas as Yn was just looking at his sacred gear as sirzechs walks towards Yn

Sirzechs:Yn join us it's a celebration

Yn:why would it

Sirzechs because of your brother and aunt having destruction magic

Yn:why should I be happy about that

Sirzechs:your not happy about it

Yn:why would I be happy towards the people that got magic before me when you and your so called wife know I had not destruction magic you both ignored me for something I couldn't control if you and your wife ended up killed I wouldn't be sad

Sirzechs:you wouldn't be sad about us dead

Yn:no I wouldn't I don't care if rias died,you died,your wife,your parents, because I have nothing to lose or care about heck I don't care about devils themselves if I got rid of my devil heritage I would've done it in a heartbeat

Sirzechs:son I'm sorry

Yn:I don't want your apology what I want is for the gremory family dead by my hands or the other factions kill you all

Sirzechs sees Yn eye color changed yellow

Sirzechs:I'm sorry

Yn:whatever have fun with your family because sooner or later it will be the last moment you and your family have before you all die

Yn leaves the party but not only sirzechs heard this also the rest of the gremory family and the guests

Grafiya:yn please don't leave I'm sorry for not being the mother you needed

Yn ignores her pleading as Yn heads to his room and got out a duffel back and puts his stuff in the duffel bag then leaves the gremory mansion without leaving a trace
