Lost in another world....again?!?!

This story is a all-out battle between my original character known as Subashi, protecter and hero of many Earths that spread arosss the multiverse. During his training he was sucked up by another Reality Rift and popped into the Hunter x hunter verse?!? Later senseing an extreme deadly power from above, he leaves only to find out someone is trying to destroy the earth and the very existence of its reality. A man named....Derias Hakaishin of Universe 7!??!
