Spoiler: Off-topic = Teresa
showTeresa actually makes a fool out of Irene, as immediately after Irene said that their individual skills were better than Teresa's, Teresa proceeds to pwn each of them at their own skills, while taking on all 4 of them at once, without even ever getting touched, LOL! Teresa at No YR was stronger than Priscilla, Irene, and Muscular Sophia. Teresa at No YR was faster than Whirlwind Noel, Priscilla, and Irene. Teresa at No YR and with normal sword swings attacked quicker than even Irene using the Quick Sword - easily parrying Irene and her Quick Sword, Noel, and Priscilla. Teresa was more agile than even Whirlwind Noel, avoiding all 4 of their attacks at the same time, never getting touched once! Teresa even dodges Priscilla's attack from behind as Irene was attacking from the front, trying to hold Teresa's sword parried-stuck in place. Teresa easily dodges Noel's and Sophia's coordinated attack on the rooftop doing a graceful backwards flip onto the ground (and is able to parry Irene's attack, which leads into Priscilla attacking from behind, as I just mentioned about earlier hehe).
So... Irene was DEAD WRONG that their individual skills were superior to Teresa's. This wasn't entirely Irene's fault, as Teresa did hide her power level, including her actual skills' levels as well. Priscilla sensed the truth: ~"How is Teresa able to keep up with me? Am I getting slower? No, that's not it, Teresa's getting FASTER! And she's not releasing any yoki still... She was holding back on me earlier! Damn you Teresa!" Teresa had superior strength, speed, attack quickness, reaction time, agility, and etc to all four of them. Their skills were NOT superior to Teresa's same skills :D
This is my assessment, but feel free to disagree
