Taking both of the talented learners to battle fair against a genius, he really is the perfect obstacle for both of them in this current arc, was rooting for PXG to win but ig that won't be it, great arc tho!
Rin so close yet so far, Isagi realising his true ego was so cold, as the start he believed "In order to change, i have to become something I'm not" now he's implying to becoming and embracing what he truly is, Such a development!
If so the ending was so very rushed gahdamn I'm disappointed:(((((
