Us four have had this bond for thousands of years.
We've been many beings.

Honorable mentions
That one time we were dragons
We where stay cats once
That time we where quads
That time we where all very gay
That world war one and two thing that happened

Basically us four have always met up and done something in each life. Meaning that my brother and cat will come back as something else while I'm still alive in this life.

My parents won't let me get any more pets but I know that once Gigen dies I will probably get depressed because bro that's 1/4 of our collective soul I just lost!
