For Relius Match up, watch out for:
-. iad j.b cross up -> j.a on reaction
-. 2c fatal -> don't do obvious air dash
-. Corner grab(7k+ damage with full Igniz Bar) -> watch out for pocking out, his grab range is huge and he can grab your 2a
You would want to sent him up to corner and rape him there, once you score knock down, he can only reversal with tension, i can say without tension he is pretty free if knocked down at corner. Led ley should always be counter grab'ed on reaction. His crouching hit box is big, Makoto 5a will catch him blocking.
