Ok next chapter is going to be a flashback to just after she moves in and they came to visit. This will explain how Sirius Black as well as Remus Lupin moves in, at least in this chapter. The following chapters will introduce her Guardians that she finds before Reborn comes into her and Tsuna's life. At the same time it will also show Tsuna's Guardians coming into his life. The amount for each chapter will as always, vary in amount of words. I will do my best with explaining what is happening. But first who should i start with?

Sirius
Ramus
The twins lightning

Cedric rain

Meet blaze in Japan by accident storm

Or the Varia?
