Yuichiro had a really good run, but it’s the end of the road for him. He can’t hope to get past the unlimited power of Bass. Yui’s sword would shatter upon impact with Bass and that’s assuming that the villain even allowed the hit to go through his barrier. Yuichiro wouldn’t even get that far since Bass is much faster than Yui can even dream of moving. It’s just a huge difference in ability here. Bass wins.
