POW POW POW!
Fake Rui launched a barrage of swift jabs at Rui. The latter merely blocked them with a guard. With his current unnecessarily high defensive prowess, he needed much less effort in order to defend against other attacks effectively. This made defense more convenient, however, Rui still hated every moment of it.
He hated his lack of flexibility, both physically and tactically. He had no leeway to evade, he needed to defend every strike even though they weren't always the optimal move had he still had his all-rounder body.
He began relying increasingly more on his passive defense and natural defense rather than active defense. In his actual body, his raw durability wasn't high enough to rely more on it than more active defensive techniques like Inner Divergence. But in this body, its innate toughness meant that he had to worry less about getting hurt.
