seriously, no one? Anyway, Im leaning towards integra
Integra was stomping Vampires with hypersonic reactions in 1-on-1. She likely could take on even a small group of them.
In comparison the best feat of Olivia was to pierce Sloth's skin. She was helpless against the immortal army alone. The same beings that were like fodder to May Chang of all people.
Amrstrong wins.... even with an arm or a leg cut off she is not likely to quit... also gotta look at battle experience in my opinion Oliver has been in more fights in her life than integra. there is gotta be a reason why she is ranked up as Major General. also she was able to pierce Sloth and Sloth has more durability than a vampire in Hellsing.... and because she is more scarier woman.
There is seemingly no 'perfect' way to truly say goodbye. So I gathered a bunch of them!
