Fusion Dimension

The Fusion Dimension (融合次元, Yūgō Jigen) is a dimension in the Yu-Gi-Oh! ARC-V, where Fusion Summoning originated. An organization in this dimension, the Academia, assaulted the Xyz Dimension, using an army of students to defeat the dimension's inhabits and turn them into cards, considering the assault a "hunting game". The Xyz survivors organized themselves into a resistance, counterattacking using the same method.
