My Yu-gi-oh Purity is Too High!

Chihiro Kujuu was reincarnated into the world of Yu-Gi-Oh! Zexal, living a peaceful life. But one day, he encountered a group of invaders in purple uniforms. They proclaimed that "fusion is the noblest way of summoning!", materialized monsters, and wantonly destroyed the city. Chihiro Kujuu stopped the fusion army and inserted the deck into the duel disk. "Country bumpkins from the fusion dimension, my name is Chihiro Kujuu, a duelist who seeks a peaceful life." "In order to protect my peaceful life, I attach great importance to the purity of the deck and the duel. There is not a single versatile card in the deck I use, all of them are slot cards and extra monsters in the relevant slots!" "And in my personal opinion, everyone present-" "Your purity is too low!"
