Some entirely new characters show up, and I have no idea why because I could not watch this episode live.
Apparently, their names would be Lagow (probably the Diablo Nemesis owner we know of already), Herschel, Keyser (?), and Cycnus (?).

Lagow owns Diablo Nemesis most likely, and the rest, based on their skintone, is : the character with the gas mask owns Duo Uranus; the two others would probably be that the character with the lighter design has Kreis Cygnus, and the last one has the Bakushin Beyblade.
(Beyblades themselves are to be discussed in the obvious Beyblade General section, hence why I erased some comments.)
EDIT : Apparently William Herschel discovered Uranus, so that would obviously mean that Herschel is the owner of Duo Uranus.
EDIT 2 : OK, somehow ã‚ュクナス gets transformed into Cycnus, which is pronounced with a hard 'c' like 'k' in both instances of the letter 'c'. Therefore, "kick-nus".
This page explains a really cool part of the mythology and perhaps offers an explanation for Kreis Cygnus' almost scary Face mark, if you concentrate on the part about Cycnus wanting to build a temple out of bones.
