Nishi regarding the manga series Iruma kun If Mafia said thatEDIT: Wait a goddamn sec. The Walter park stuff. The fact we're in Spain. The owner is Ronove isn't it. Oh my god.
I didagree on the person behind the mask. Any resemblance to the 13 crown would be coincidenceMost likely the one with the buffalo mask could be Amaymon and the one with the mouse/rat mask could be Behemolt and the one with the dragon mask I think could be Gyatz the guy with the rock music from the music festival or one of the Oroboros prison prisoners from the main manga series.
From what I remember in the main manga series Sabnock Sabro before considering Iruma a rival considers Azz-kun a rival. Hence the challenge that Sabnock Sabro gives to Azz-kun in this series. Here are the 2 brothers Niro and Ichiro Androalphus who are some presenters for this manga series.
Also those 3 masks are a reference to the beasts that attacked Walker Park in the main manga series. So most likely Ronove Lumiere could be the owner of this place, because from what I remember Nishi said about Lumiere as if he were an aristocrat in this series.
