Spoilerwarning ..

At this moment (Episode 15) he is suspected to be responsible for a so-called "attack involving xyz-monsters" on a teacher from LDS (the place of the attack had marks similiar to those at the place were he first fought and was also a warehouse - whatever the teacher was doing there is out of the question apparently).

He could be sighted by any viewer to be either stalking Yuzu Hīragi (this seems likely because he also followed her and Sora to the place of the first attack) on her way to LDS Headquarters or observing those particular Headquarters (which had extra security in action - this also seems likely since he only dueled the first time when he got knowledge of Sawataris involvement with LDS). When he was challenged to a duel by the Gem-Knight-Fusion-Summon Kid (Masuki?) -to avenge her teacher or something- while Yuzu and Sora Shiun'in were talking to him, Yuzu tried to stop that duel from happening and suddenly her wristband glowed again like before and the black duelist was gone. Nobody seemed to care that Yuzu apparently had a magic wristband apart from herself though and then Yuya showed up (again!).

I think it highly likely that the black duelist might possess knowledge about LDS (either from the future or just some dirty behind-your-back actions) and has some kind of relation to Yuzu. He could be her real quest to become stronger, but that seems unlikely, because why would she want to do anything about LDS? One could argue LDS tried to overtake her school, but that only happened AFTER he attacked Sawatari..
