Primary Weapons: The Nata is the best combination of the weapons in this category it has the weight behind it and a strong blade. Plus, its length is great enough to reach a reasonable distance and can hack off a limb or two. The Baseball Bat comes in second for its great power, but it takes a decent amount of energy to be put into each swing.
 * 1st: Rena Ryuguu
 * 2nd: Satsuki Miya
 * 3rd: Mai Mashiro
 * 4th: Rio Miyaichi

Secondary Weapons: Mai's nightstick is the weapon that is most meant for traditional combat, but the lead pipe ain't no slouch here either due to the power behind it. Rena has been in more physical confrontations which will assist in overpowering Mai here, but the nightstick is collapsible giving a sort of stealth advantage. Still, I would've given the edge to the baton had it not been for the fact that the metal pipe is nearly three times its length. TBF
