What font?

Arrus Black  Suggeriti da cassie2006 
Huni Bitstarrb  Suggeriti da Y1el 
Itsadzoke  Suggeriti da classyyrikka 

I think the font is customized/made by SM Ent, but here's something close.

i know it's late but just here to inform you the closest font and yeah it's true that the logo's just customized.

U and N in Run used lowercase and made thinner

This is a clone of Arrus Black, which has already been suggested.
