Dante & Nero vs. Raziel & Kain

Nero & Dante have to try and slay Raziel & Kain, while Raziel & Kain are thinking that silver haired demons would make fine (sex) slaves.

Nero gets his trusty sword, his trusty revolver, & DB but no DT.
Dante has E&I, Rebellion, Lucifer, Gilgamesh, & Yamato along with DMC4 DT. Basically DMC4 Dante without the other guns.

Raziel has all his Reaver enhancements, including the Spirit Reaver. He also has collected all the souls of his brethren. Basically Raziel at the end of Defiance. Raziel cannot switch to the Spectral Realm, and his health does not drop due to being in the Material Realm.
*NB: if Raziel somehow touches Kain, Raziel will not get sucked into the Reaver. Reason is below.
Kain has the Soul Reaver, which for this fight, can suck souls, & can also suck blood. He has his spells from BO1, and all his Reaver enhancements from Defiance as well. His health does not drop either.

Round 1:
Raziel vs. Nero.

Round 2:
Kain vs. Dante.

Round 3:
Raziel vs. Dante.

Round 4:
Kain vs. Nero.

Round 5:
Raziel & Kain vs. Dante & Nero.

Characters, if killed, are resurrected after the round is over. They are also given time to rest and get back to full strength.
No prep whatsoever.

First to 3 victories, wins.
All 5 matches must take place though.

Even with the restrictions I see the devils taking most if not all of the points.

The Blue Rose and Red Queen's explosive flame attributes fit in well against vampires. The DB, being able to deflect Savior hits, hold the whole thing back and crush its face with enough force to make a shockwave felt hundreds of meters away, with this he can probably crush the pair. His normal left arm is stronger then either of the vampires just for measure.

Raziel shouldn't pose too much of a threat, only Kain. With all mentioned ^ Nero may pull it off, defiantly if DT was accessible.

Edit: Oh yeah, Dante. He brings in the gold if Nero doesn't.

Hard one to call, Round 1 probably Nero

Round 2- Kain by a hair

Round 3- Dante

Round 4- Kain

Round 5- Kain, Raziel and Dante.
