When this words came by ("I might be the next one") I was like WHAT THE PACKING TAPE! I'm glad Tamaki went to stay at Shouta's house. I would very much like the both of them to end up together but Tamaki has a lot of extra baggage so he needs to fix it first or maybe fix it together with Shouta. I hope this manga will end well...
Okay so maybe she really is Asta's mother with that eleventh chapter with her saying "I won't let it go this time" plus with that panel of her and a basket in front of someone's home. Her saying that, would mean that she let go of Asta, afraid of sucking more of his life force, and Ribe kinda replaced Asta in her life so yeah, she won't let it go this time. ╮( ̄▽ ̄)╭
I was reading this chapter slowly, panel by panel, I was making theories inside my head but still, just whose kid is Asta?! We found out his devil was an inferior one with no mana like him and with a name we still don't know if it was his name from the start or a given name by his "mother". The devil's "mother" absorbs mana just like one of his grimoires' sword, but still where did Asta came from?! I'm frustrated! I need answers! (╯°Д °)╯╧╧
I really thought the guy was invisible but hey hey hey
