Q: Between Kotomine, Bazett, Kuzuki, Melty Blood’s Miyako, and Kishima Kouma, who’d be the top 3 in a purely hand to hand fight with no weapons or magecraft?

A: I’m excluding Kouma since his existence itself has become a mystery.
And even if he didn’t have that nature, he’s like an athlete caught by drug testing.
Out of the four left, the winner in pure strength is Bazett.
If it’s limited to one match and a surprise attack, then it’s Kuzuki.
And if it’s the Kotomine from ten years ago, he’s stronger than Bazett overall.
