19(Crossover)

An Au where after Mikey disbands Toman, he does not create another gang but he and Sanzu move to another city(Makochi) to get away from all the bad memories(and keep in contact with at least Mansuke).

In that city, they are able to create a life they can say they are happy with despite their losses and even find love and have kids(Mitsuki Kiryuu and Choji Tomiyama) who they try to raise to have a better life then they did even if both of their kids ended up joining/creating a gang(Choji won't end up as bad in canon...Mikey himself would beat his son for doing what he did...unless Choji also have Dark Impulses...the writer can decide about this).

They hadn't been in contact with any of their old friends until the parent's day at Furin when they saw that with one of the first years was accompanied by Takemichi(Nirei can be his child or nephew...and yes, Mikey went with Sanzu...but if you want it can be Mikey x Sanzu or Mikey x Oc and Sanzu x Oc, it is up to the writer) or another of their old friends(or even family member since it could be Takeomi or Senju).

How the reunion would go, the kids reaction to the past they hadn't totally known of their parents, etc is up to the writer.
