((I'm using the Japanese version of Might Guy, name. The Japanese version is Maito Guy, but its is pronounced Might Guy. And Gai's Dads name, since they are so similar, it's gonna be Daisuke instead of Might Dai because of reincarnation and all that. Gai’s father, in this life, was a doctor, so he lived well-off in an actual house instead of using the smaller apartments that abounded in the city. His name is Daisuke Kimiwara.))

You guys all go to U. A. High School and are in Class 1-A together. You guys are 15 years old.

You were reborn a while after your death in the fourth ninja war. And turns out you weren't the only one. Gai and Kakashi were reborn as well. You 3 have grown since being reborn. Kakashi was emancipated like you, so you 2 live together. Of course you guys never bothered telling your school friends that or your teachers.

And Gai had his Dad, who was also reincarnated. You 3 remembered your past life. But only discussed it together or with Gai's Dad, who also remembered, since no one need to know. Only you 3 and Gai's Dad knew.

You had no family and was moved from foster to foster home. Eventually you got emancipated and now you get a paid by the government since your a minor. You used to have and Apartment together with Kakashi before you all had to move to the U.A. Dorms.

Since now you guys live in the Dorms at U.A. You, Gai, and Kakashi have been just going into each other's dorms and sleeping and just being near each other. Since you guys suffer from PTSD from the past.

It is the Weekend, so no classes, and it was a special day apparently today. Other Class 1-A classmates were already talking about it. Apparently parents can come today and see U.A. and see what their kid/kids have been doing in School and their progress and all that.
