The rest of the Student Council members fall as they will lack the ability to fend off Guts (with and without Berserker Armor). Touga milking the power of the Sword of Dios will drag the battle out a bit as a single swing was capable of shattering one of the stone edges of the Rose Duel tower from a distance during his second fight with Utena. However, Guts is quite fast for a man of his size with or without Berserker Armor. It would be a matter of time before Guts closes in enough distance to hack up Touga. With the Dragonslayer's mystical properties thanks to slaughtering enough apostles, the sword won't be getting shattered by the power emanating from the Sword of Dios like Touga had pulled on Utena.
Even without closing in distance, Guts does have other ranged weapons on hand to help him out such as his cannon and the crossbow attachment for his prosthetic arm.
