The disciples of the Void Sect

Ren was liking his newly summoned butler, Walter. After a few weeks of living with Walter, the butler's presence grew on Ren, it was like having a loyal and helpful dog. Walter was pretty much the perfect butler, he cooked for Ren, cleaned Ren's things, and would give advice when Ren needed it. There was even a time when Ren had fought Walter. The old butler was plenty powerful and had a lot of battle experience, it was fun fighting him. At this point, Walter could anticipate everything Ren wanted before he even thought of it. 

Ren was also continuing his training with his various incarnations. After summoning Walter, Ren no longer continued summoning other beings. At first, he was planning to try and summon all of his past incarnations' summoned beings, but after learning how large almost all of those summons were Ren changed his mind. So instead right now Ren was learning to use spatial spells.
