The Key to the Dimension of Hunter Fandom

The girl was taken to a strange space that connected the portals of various dimensions with a magical key called the "Key of Dimension". For her beloved Killua, the girl chose "Hunter". He mindlessly chose Chrollo's appearance, Killua's age, and the time period half a month before the Kuruta tribe was wiped out, and the girl who inspired to save the Kuruta tribe traveled through time in a gorgeous way. Possessing the useless ability of "Dimension Summoning", he was abducted and sold to a slave trade meeting as soon as he entered the city. Could the story end here? ! No! I want to save myself! Leader, I am your biological sister, come and save me! Brother Yi Mi, you don't need to charge accommodation fees, right? Hisoka is such a pervert, please stay away from me! The road ahead is bumpy, and if you want to be with your beloved Killua, you still have a long way to go!
