Lora trained on two of Dante's main outfit, think it's his DMC3 and DMC4 ones.
Weights 0.7 - 1

most of his clothes should be baked in.

seems ebony & Ivory and Rebellion can gen, using a weapon model like Fallen's Unlimited Blade Works may help, but as they weren't the main focus not sure how good they would look.

overall: black_pants, boots, belt

overall optional: sword, gun, handgun, dual_wielding

DMC3: navel, midriff (not sure if Tube_top or strapless would help)

DMC3 optional: underboob

DMC4: black_shirt
Unlimited Blade Works: Unlimited Blade Works | Weapon LoHA [BETA] [Unsheathing Sword, Link Master Sword, Lightsaber, Dual Wielding, Scythe, Shield, Staff, Trident, Knifes, Bow with Arrow] - v0.4 | Stable Diffusion LyCORIS | Civitai
(quick aside, saw some fem Dante while getting the dataset...didn't know i wanted that)
